				<p><strong>Well said</strong></p><p>Someone once posted something that made the difference between science and fields such as economics crystal clear.</p><p>
He or she pointed out that, in a real science or in a field like engineering, you can pretty much use books from 1900 and 1910 and 1920 and 1930 and so forth, and while there will be new information added with each that revises the previous books, you won't have complete revolutions, and you especially won't see these revolutions tied into the personality of the proponents, the dead giveaway tip-off to a field that is dominated by the personalities of the folks running the show at that moment rather than by any sense of finding out how things actually work.</p><p>
You pick up a chemistry or mechanics book from before World War II and you realize how smart those people were who figured out an amazing amount of stuff without benefit of computers. &nbsp;In contrast, economists are always writing about how the dark ages of economic thinking -- which always ended just before the writer got the PhD -- were periods of incomprehensible mistakes that needed the new Truth to be revealed to the waiting world (with the exception of the historical figures the writer wishes to claim kinship to).

				<p><strong>Good point, JMG<p>Most of the engineering used to size the 777 wing structure was developed long, long ago. The only thing new in structural engineering is the use of computers to run finite element modeling programs (and it is always wise to check those results against classic beam bending and shear equations).<p>
And of course, economists &nbsp;have done and will continue to do a lot of good stuff.

				<p><strong>The world is complex<p>First, BioD, thank you for a very well-argued and thought-provoking article. And thank you for <a href="http://gristmill.grist.org/story/2007/12/12/115814/50/#comment125" rel="nofollow">your civil note to Jerry Taylor on the <a href="http://gristmill.grist.org/story/2007/12/12/115814/50" rel="nofollow">On Science vs. economics string. <p>
It was beginning to dismay me that, having invited a guest to argue his case, readers immediately began attacking him in the most disrespectful manner -- as much for what they thought he represents as for the perceived holes in his arguments. The appalling lack of civility displayed on that string does not bode well for the future acceptance of such invitations by people whose views can be expected to differ sharply from those of the majority of Grist readers.<p>
By contrast, your approach, including this post, is a model for the way that debate should be conducted.<p>
----------------<p>
I think that JMG is not entirely wrong when he describes economics as "a field that is dominated by the personalities of the folks running the show". Of course, other fields have had moments when personalities weighed heavy, and when there was disagreement over basic principles -- for example, plate tectonics in the middle decades of the 20th century, and some of the outlying theories of quantum physics even now. The problem for economics is that it remains constantly in such a state of flux. Of course, in that sense economics is not alone: think of the wide variations in advice from the medical profession concerning diet.<p>
We should not confuse micro-economics -- which is the branch of economics that has the most to say on the design of policies targetted at individuals or narrow economic sectors -- with macro-economics (and especially the practice of economics that has to rely on large predictive models), much less the world of corporate finance, which I think is what many Grist contributors have in mind when they conjur up an image of their "economist" boogieman.<p>
I would also agree (partially) with the point that JMG makes about an insufficient interest among economists -- that is to say, academic economists -- in "finding out how things actually work". Many do, of course, but at a rarefied level that frequently proceeds down obscure paths that require ever more complex equations that few people other than the authors themselves understand.<p>
However, many practicing economists ARE very much interested in "finding out how things actually work". But they face, like anybody working in a social science discipline, numerous constraints on being able to conduct controlled experiments. Moreover, they are typically having to work with data that are imprecisely measured (unlike, for example, the measurements with which engineers work).<p>
The question is, where does that leave us? Clearly (in my opinion, at least), we cannot dispense with the insights provided by economists. To do so would make policy even more prey to power politics and special interests. But I agree, BioD, that economists need to be clear that any predictions of the macro-economy that they make are subject to wide margins of error, and that the main value of their models is to organize the information in a logical way so that others may look at what happens when the data or assumptions are changed.<p>
Just a final note: it is not only economists who have sharp differences about the carrying capacity of the Earth. Witness, for example, the ongoing debate among scientists trying to estimate the long-run potential for biofuels. At one end, we have the IEA Bioenergy Task Force 40 group, <a href="http://gristmill.grist.org/story/2007/12/13/11532/535#3" rel="nofollow">who predicts that by 2050 the world will be able to produce -- without deforestation and without an unnecessary food versus fuel debate -- 1300 exajoules (EJ) worth of bioenergy in a sustainable manner. That is around 6 times the total amount of oil currently consumed by the world.<p>
At the other we have scientists like Sten Nilsson, Deputy Director of the The International Institute for Applied Systems Analysis (IIASA), who, using a slightly different approach (as reported in "<a href="http://environment.newscientist.com/channel/earth/energy-fuels/mg19626343.800-is-the-biofuel-dream-over.html" rel="nofollow">Death of the Biofuel Dream?", New Scientist, 15 December 2007, pp. 7-8 -- subscription required), estimates that, after taking into account the land needed to produce food and forest products for a growing world population, there will be very little if any "spare" land that could be devoted to energy crops by 2030.<p>
Keep probing the assumptions, is all I can say.</p></a></p></a></p></p></p></p></p></p></p></p></p></a></a></p></strong></p>

				<p><strong>Guten Dag</strong></p><p>I'm an Austrian (in the economic sense). &nbsp;I really liked your post</p><p>
It's almost an inhuman standard to avoid relying on unreliable predictions. &nbsp;As an example, the (excellent) Casten post you link to goes thorugh a lot of funny stories about the inability of economists to predict accurately, then in point 4 reviews his theory that he understands exactly how to achieve several mutally-conflicting goals if only his preferred technological solution were put in place.</p><p>
You end your (also excellent, in my view) post with:</p><p>
"It is a possibility that overzealous attempts by liberal types to fix the problem could make matters worse, which I suspect is Taylor's main concern, which I share. We need to make sure that does not happen but we also need to take immediate steps to reduce greenhouse-gas emissions."</p><p>
I assume that you have made an implicit prediction about the net economic (in the broad sense of the term) impacts of this. &nbsp;Can you make it explicit?</p>

				<p><strong>Prediction</strong></p><p>I think there is a tension in modern neurobiology and psychology in that (1) our brains are wired for thinking about the future, and (2) we are bad at "predictions."</p><p>

It's hard not to stretch for some questions though, because not to stretch is to accept whatever you get.</p><p>
We want to know if we can burn this coal. &nbsp;We want to know if Social Security is sound. &nbsp;What else can &nbsp;you do? &nbsp;You predict.</p><p>
BioD also predicts that we will act on our predictions ;-). &nbsp;I'm sure we will, but some mornings I'm not sure that our actions will be sufficient. &nbsp;Look at "managed fisheries" as a model of prediction and action. &nbsp;Managed fisheries should not collapse ... except they do. &nbsp;All the time.</p><p>
Sometimes the end-run is a policy that acknowledges our poor predictive abilities ... like "no take" marine preserves ... or maybe a big walloping carbon tax.</p>

				<p><strong>It would be so easy...<p>I believe many of us who complain about economists do so out of our distaste for the assumption that MORE should automatically be a goal. Sadly the biggest source of funding for academic economists and income for other economists is big business. Their goal is an expanding market, growing revenue and increasing profits. That means we are bombarded with way too much growth-centric rhetoric from economists in the media.<p>
I think this growth fever has even infected many of the "liberals" discussed in this thread. I wonder why so much energy is invested in trying to find the next heroic technology fix for problems that could be so easily remedied if we could optimize the size of our population on the planet and cease clamoring for ever-increasing economic throughput. Hah, everyone will think! What is so easy about that? Too true. Human nature being what it is, these easy fixes are probably just beyond our grasp. Too bad, because &nbsp;they don't include all the risks of catastrophic unintended consequences that come with techno-fixes.

				<p><strong>Specifics, Growthbuster?</strong></p><p>Growthbuster,</p><p>

Some people point to empowerment of women, and how that leads to fewer children per couple, or the effects of increasing urbanization on family size, and suggest that population will take care of itself (eventually) if these trends continue. I presume you're not in that camp?</p><p>
Are you making an appeal for voluntary restraint in family size? If so, how effective do you think such appeals will be?

				<p><strong>Good questions, Ron Steenblik</strong></p><p>I'm afraid I haven't got any answers but it's something I've been thinking about. Over population is the elephant in the room. </p><p>
At some point I think mandatory limits on family size may become necessary. Imagine how many more millions of poor people there would be in China if they had not instituted their one-child policy. Education and empowerment of women are the are better ways of reducing population growth but we've left it too late.</p><p>
Limiting population will be yet another facet of the great moral crisis we have brought upon ourselves. Which is worse? To restrict personal freedoms or to bring billions into a life of starvation and hardship? There are no easy answers except to say that doing nothing is the worst inhumanity.</p>

				<p><strong>Prediction and Creation<p><br>
Prediction isn't just about stating what you think will happen and sitting back and watching.<p>
It's a creative process where you actively "make" it happen.<p>
The question that rarely gets asked is "what do we want?"<p>
How many people do we want?<br>
How much technology should we have?<br>
How many mp3 players per person?<p>
All this arguing over "footprints" -- well, maybe someone has a reason to have a big footprint...maybe not.<p>
As far as Cato, I think optimistic predictions have a good benefit in the sense that they make people relax and not work so hard. &nbsp; Not working hard makes less CO2...that's what you want right?

				<p><strong>Prediction vs. anticipation<p>Odo and jabailo,<p>
Humans don't actually predict, they anticipate. The difference is that prediction involves a formal statistical inference approach, which as Odo points out, humans are not wired for. We need models and computers to come up with predictions and since our models (especially those used in economics) are generally flawed the predictions are too. A prediction is saying what WILL happen in the future, all other things being equal. It is a passive statement, as jabailo alluded.<p>
Anticipation is a fundamental property of all <a href="http://faculty.washington.edu/gmobus/ForagingSearch/Foraging.html" rel="nofollow">animals that move in their environments. Anticipation is the use of an encoded causal model, using a leading indicator cue to change the future! An anticipator is attempting to produce a good outcome from a potentially bad situation (e.g. getting eaten) through threat avoidance, or a better outcome through resource capture.<p>
Odo is right about humans not being very good predictors, at least as far as their mental capacity is concerned. But formal models are sometimes good. Especially when they incorporate new information (like Bayesian learning) from empirical studies, as has happened with the climate models over the last decade.<p>
In fact these models, if believed by our leadership, could become part of an anticipatory political system. The IPCC has pointed the way to what can happen given the cues we are now measuring (i.e. CO2 emissions). The UN, with the support of the US could act as an anticipatory system that seeks to mitigate a bad outcome. Its the support part that is in doubt.<p>
Economic models and their subsequent predictions might seek to be anticipatory systems coupled with policy implementations. But let's face it; bad models (or incomplete ones that are not updated with experiential information) will fail. I think the record of economic models in producing real effective policy responses has been abysmal. And unless they start basing them on the real underlying phenomena that give rise to economic activities and processes they will continue to produce misguided policies.<p>

				<p><strong>lol<p>Mark, are you saying they "can" predict the future in the sense that we can't stop them? ;-)<p>
I hope not in the sense that they "can" be consistently accurate. &nbsp;If "the book that could not be named" was not enough, there is always "Expert Political Judgement." &nbsp;From <a href="http://www.newyorker.com/archive/2005/12/05/051205crbo_books1" rel="nofollow">the New Yorker review of that:<p>
Tetlock also found that specialists are not significantly more reliable than non-specialists in guessing what is going to happen in the region they study. Knowing a little might make someone a more reliable forecaster, but Tetlock found that knowing a lot can actually make a person less reliable. "We reach the point of diminishing marginal predictive returns for knowledge disconcertingly quickly," he reports. "In this age of academic hyperspecialization, there is no reason for supposing that contributors to top journals--distinguished political scientists, area study specialists, economists, and so on--are any better than journalists or attentive readers of the New York Times in `reading' emerging situations." And the more famous the forecaster the more overblown the forecasts. "Experts in demand," Tetlock says, "were more overconfident than their colleagues who eked out existences far from the limelight."</p></a></p></p></strong></p>

Tetlock also found that specialists are not significantly more reliable than non-specialists in guessing what is going to happen in the region they study. Knowing a little might make someone a more reliable forecaster, but Tetlock found that knowing a lot can actually make a person less reliable. "We reach the point of diminishing marginal predictive returns for knowledge disconcertingly quickly," he reports. "In this age of academic hyperspecialization, there is no reason for supposing that contributors to top journals--distinguished political scientists, area study specialists, economists, and so on--are any better than journalists or attentive readers of the New York Times in `reading' emerging situations." And the more famous the forecaster the more overblown the forecasts. "Experts in demand," Tetlock says, "were more overconfident than their colleagues who eked out existences far from the limelight."</p></a></p></p></strong></p>

So <strong>of course</strong> economists can predict the future. &nbsp;That's what true science is all about. &nbsp;Now, Arnold Kling may be wrong in his prediction, but he's made a prediction, based on scientific principles. &nbsp;(Specifically, his prediction is based on the growth of computing power in the 21st century.)</p><p>
Where has any anyone from the "environmental economics" community made any falsifiable predictions about future world economic growth?</p><p>
"I hope not in the sense that they 'can' be consistently accurate."</p><p>
Concerning future economic growth, the record of economists is much better than that of environmentalists over the past 50 years. &nbsp;The world economy has never collapsed. &nbsp;In fact, per Angus Maddison ("The World Economy: A Millenial Perspective") there have never even been even two straight years of negative per-capita world economic growth since 1950. &nbsp;In fact, only 3 of those 57 years have had negative per-capita growth at all...and all have been less than 0.5 percent. &nbsp;That actual experience can be contrasted with the pathetic record of warnings of economic doom from environmentalists in the past half-century.

				<p><strong>Predicting happiness</strong></p><p>Odo: 'My recollection is that Gilbert makes a case for human nature (and happiness) strongly centered in the word "prediction."'</p><p>
My recollection is that he makes a case for how badly people 'predict' their own happiness under various scenarios of gain or loss. In other words, humans are lousy predictors of future situations involving how they will feel. Rather, they base their estimates of their happiness on a causal model of how something ought to make them feel. And they consistently get it wrong.</p><p>
Robin Hogarth makes a good case for the fact that what people do is not prediction (in the technical sense) because that implies statistical inference based on probability theory. People routinely show that their estimates of likelihood for two or more mutually exclusive events often sum to more than one. Check out "Judgment and Choice" by Hogarth. Its a good read.

				<p><strong>Yep Ron</strong></p><p>I bet the oil trader has his own hedge fund now, right? &nbsp;Hehey.</p><p>
This is what I learned too, about expert traders that base their trading theories on the "science" of economics. &nbsp; Remember the Long term capital management hedge fund crash in the late 90's. &nbsp;I bought at the bottom of that crash and made my first 5k in the following run up due to the Fed lowering/bail out. </p><p>
The LTCM doods were expert economists, professors with supercomputers and airtight, ground breaking trading theories that couldn't lose. &nbsp;they borrowed 5 billion, then leveraged that to 100 billion. &nbsp;But they lost.</p><p>
And the fed bailed the banks out that backed them &nbsp;by lowering rates on an emergency basis. &nbsp;That started the infamous "bubble".</p><p>
Anyway, what the new right corporatarians are trying to sell us is that the 'free' markets, the same ones that crashed from LTCM manipulation, and are about to crash from the mortgage crisis turned global credit crisis. &nbsp;These same markets manipulated by these same type of insider trading hedge funds, are the best possible cure for GHG climate disaster.</p><p>
They will "hedge" the risk for us all, taking a mere pittance in profits for assuming all that risk. They will trade weather futures and carbon and insurance company junk bonds and save the planet! &nbsp;all with no new taxes!! &nbsp;and no inept government interference in market efficiency!!! Sound great! </p><p>
I spent a few months arguing with Jerry and his minions over on the Cato site. &nbsp;It's difficult to stomach, but illuminating. &nbsp;All the latest, greatest corporate friendly taking points are repeated over and over in very complex theory laden terms.

				<p><strong>Statistics</strong></p><p>"Robin Hogarth makes a good case for the fact that what people do is not prediction (in the technical sense) because that implies statistical inference based on probability theory."</p><p>
Is that an important distinction? &nbsp;When an economist says on TV that growth will be X and inflation will be Y, do we know that he did anything other than poll his gut?</p><p>

				<p><strong>Congratulations, BioD</strong></p><p>This is brilliant, some of your best work, and all the more impressive that you make it look as though you dashed it off in a half an hour.</p><p>
Also admirable is your attempt at translating that fragment of Amazingdrxese. &nbsp;Frankly, though, I have no way of judging how accurate it was. &nbsp;To me, not knowing anything about such matters, it looks rather like trying to translate Beowulf, and coming up with a Grendel's Mother who looks like Angelina Jolie, power-boobs and all.</p><p>
Here is a snippet from Sean Casten's post, which you say you like:</p><p>
&lt;&lt;<br>
I recently joked to an economist friend that economics is the only discipline where you can get fired if you admit you are unable to predict the future. The comment has too much truth in it to be particularly funny, though.<br>
&gt;&gt;</p><p>
Funny, I always thought of economics as basically a handmaid of history, past-oriented, a method of explaining certain events in the stories of human beings. &nbsp;So, for example, historians of the ancient Mediterranean might wish to relate the so-called (ha!) Fall of the Roman Empire, and the establishment of new, more restricted cultural centers in Late Antiquity, to the disruption of the normal supplies and distributions of food of the Pax Romana.</p><p>
Also, there are the examples which you like, as also does Jared Diamond: the Easter Islanders, and the Classic Lowland Maya, drasticly diminished by an apparently anthropogenic deficiency of resources; and the Anasazi (whom we are now asked to call Early or Ancestral Puebloans, in deference to our brethren the Pueblo peoples of today, who dislike that non-Pueblo Navajo term, meaning something like "enemies of our ancestors" or "ancestors of our enemies"), drasticly diminished by a natural aridification event that was beyond their power to cope with.</p><p>
By contrast, predictive, future-oriented economics, the sort that you gotta know about if you want to grow up to be, say, Secretary of the Treasury or Chairman of the Fed, is to true economics, rather as technology is to science.</p><p>
Sean Casten also wrote:</p><p>
&lt;&lt;<br>
In Consilience, E.O. Wilson differentiated between the sciences and the pseudosciences by noting that only the former are verifiably predictive. By this definition, economics is a pseudoscience. Arguably, so is much of medicine, and this is fine so long as the discipline is honest enough to acknowledge its limitations. My beef with economics is that it keeps on dogmatically asserting the accuracy of its crystal ball in spite of all available evidence to the contrary.<br>
&gt;&gt;</p><p>
OK, the beef is truly there, if in fact economists behave that way. &nbsp;Medical doctors diagnose, prognose (does that verb exist?), prescribe and treat, on the basis (ideally) of probabilities carefully constructed from the records of all earlier medical cases. &nbsp;If your case turns out differently than what your doctor expected, then your doctor (ideally) makes a note of what happened counter to expectation, the note goes straight to the medical data banks, and all doctors in the future will take it into account.</p><p>
But, you mean to say, economists don't work like that?!</p><p>
In the third quote-box in your post, you quote Jerry Taylor:</p><p>
&lt;&lt;<br>
Strictly speaking, no economist would contend that "infinite growth of some meaningful quantity is possible in a finite space." &nbsp;If nothing else, infinity means forever. ... [And then he says something about deciding] what our definition of "finite space" might be.<br>
&gt;&gt;</p><p>
Well, I have no idea how economists like to use these terms, but it is not true that "infinity means forever." &nbsp;The infinity of time was already a controversial concept in ancient philosophy; and modern cosmology has fundamentally restructured the problem for us. &nbsp;So, the infinity of a being existing in time is not impossible to conceive of, but that depends on its being true that time itself is infinite. &nbsp;</p><p>
Also, there are other kinds of infinity than infinity in time and infinity in space. &nbsp;A line segment is by definition (ha!) finite, and yet it contains an infinite number of points. &nbsp;Paradox-loving theologians, dwelling on the ancient, common-sensical truth, "finitum incapax infiniti," "what is finite cannot contain what is infinite," presumably like to ask if that is refuted by the line segment and its infinite number of points, as they consider that Christmastime Mystery, the Incarnation of the uncreated, eternal, perfect-in-every-way Word of God, in the finite baby born of the young girl Mary.

<p>Chickens are our cousins!  So are fish!  So are other sentient animals!  Let us learn to be kind.</p></br></br></br></br></br></br></p>

				<p><strong>Answer to Odo</strong></p><p>Yes it is an important distinction. This is pretty standard stuff re: human mental models (c.f. Johnson-Laird, Philip, (2006). How We Reason, Oxford University Press, Oxford.) vs. formal statistical inference. If an economist is going with his gut then we are all in very deep trouble.</p><p>
This isn't to say that statistical modeling is always that much better. The statistics may be flawless, but the underlying assumptions and what you choose to measure may be horribly askew. Isn't that what we are claiming about much of economic prediction?</p><p>
The reference to 'Tetlock' is obscure to me.</p><p>
As for 'true' scientific prediction, you claim that only deterministic systems count. This is terribly dismissive of the whole arena of stochastic systems that are, by definition only knowable by statistical inference. I think most biologists and many chemists would be surprised to hear that they are not doing true science.</p><p>
In fact, even deterministic systems (involving gravity as in your example) cannot be modeled without some statistical work. Measurements are always imprecise and noisy. It takes many observations and averaging to collect the 'data'.</p><p>
In the example you mention, the solar system and predicting the position and momentum of bodies, it turns out that the equations are not closed form and the solutions have to be computed by mathematical modeling. Even then there is inherent error in the prediction!</p><p>
I would have said that true scientific prediction is ALWAYS approximate, and therefore of a statistical nature. But that's just me nitpicking.</p><p>

				<p><strong>Prediction and scientific method</strong></p><p>As a civilization we have found scientific methodology to be extremely useful and we apply it to some degree in almost all areas of human study and endeavor. We observe, we analyze, we seek out and then test predictive rules to measure our understanding of the physical universe and all it contains. Economics is no exception. But then, neither is astrology or portrait painting. Astrologers depend upon scientific observation of the heavenly bodies for the framing of their analysis. Painters have for centuries applied scientific methodology to the discovery of durable pigments and binders and effective techniques. But few would describe these areas of activity as sciences. The use to which the science is put inevitably goes far beyond the scientific method &nbsp;itself. This condition would also appear to apply to economics: the study of economics includes science, but that is not to say it is science.</p><p>
The most glaringly self-evident limits of scientific method in economics are threefold. One is the extreme difficulty (impossibility?) of isolating particular effects for the purposes of study - no economic system can be effectively separated out from the cultural matrix in which it resides. In economics there is no mixing of two defined substances in an inert vessel to see what happens.</p><p>
The second limitation is the undoubted effects of the observational study itself, both directly and through its interpretation, upon the outcome of the observed phenomena. The prediction enables the result - "if I say it three times it (becomes) true". </p><p>
The third obvious limitation is the extremely long timescale of the experimental and observational platform itself and the major changes in the baseline assumptions that can take place within that timeframe. It took six decades for command and control communist economic theory to be tested in the Soviet Union - and who can say for certain for what reason that experiment failed? The variables of input, from the devastations of WW11 to the Russian fondness for vodka, are endless.</p><p>
There is a fourth problem which springs from the uncertainties inherent in the first three, which is the extreme vulnerability of the resulting analysis to interpretation according to political and ideological principles rather than scientific ones. The huge and constantly growing volume of available economic data allows a comforting illusion of scientific objectivity. This illusion founders on the equally huge volume of uncontrolled cultural and other variables. This is not to say that economic inputs (and predictions) are useless in our deliberations on the climate change crisis. But it does suggest they can hardly be considered to have the full weight and authority of definitive scientific process behind them.

				<p><strong>Yes, science is all about predicting the future</strong></p><p>Many sciences don't predict future</p><p>
I know that, you know that, but...</p><p>

				<p><strong>Cold fusion certainly is falsifiable<p>Just today I got into a discussion with a usually very smart guy who wanted me to buy into his belief in cold fusion (expressed as "there's something there" and "the effect has been replicated numerous times" and similar statements and appeals to authority, such as the claim that the Navy is investing in cold fusion research). &nbsp; &nbsp;<br>
Problem is, there's no falsifiable theory on offer, just wild claims about governments suppressing positive results, etc. etc. etc. <p>
Your friend may not have a falsifiable theory. &nbsp;But there certainly IS one: &nbsp;The heat and reaction products (e.g. helium) observed in experiments can ONLY be explained by nuclear fusion (e.g. not be chemical reactions or contamination or instrument error).<p>
See here for an interesting report abstract:<p>
Excess power was measured in 28 out of 94 electrochemical experiments conducted using palladium or palladium-alloy cathodes in heavy water. Reproducibility continues to be the major problem in this controversial research area. Based on our experiments, this lack of reproducibility stems from unknown variables in the palladium metal. The best reproducibility for excess power was obtained using palladium-boron materials supplied by the Naval Research Laboratory. Our basic isoperibolic calorimeters were capable of measuring excess power with a sensitivity of &#177;1% of the input power or &#177;20 mW, whichever was larger. Calorimeters that are capable of detecting excess power levels of 1 watt per cubic centimeter of palladium are essential for research in this field. Results from our laboratory indicate that helium-4 is the missing nuclear product accompanying the excess heat. Thirty out of 33 experiments showed a correlation between either excess power and helium production or no excess power and no excess helium. The collection of the electrolysis gases in both glass and metal flasks place the helium productionrate at 10^11 to 10^12 atoms per second per watt of excess power. This is the correct magnitude for typical deuteron fusion reactions that yield helium-4 as a product. Anomalous radiation was defected in some experiments by the use of X-ray films, Geiger-Mueller counters, and by the use of sodium iodide detectors. There was never any significant production of tritium in any of our experiments.<p>

P.S. &nbsp;I don't "believe" in cold fusion...because I don't "believe" in anything. &nbsp;If cold fusion exists, it's certainly at the very top of human discoveries in all of history. &nbsp;However, I'm skeptical; but I'm open-minded. &nbsp;I await more evidence.

As for the two discoveries related to Earth history in Mark Bahner's list, the Chicxulub crater at the Cretaceous/Tertiary boundary, and the fossil remains of the Late Jurassic "missing link" between reptiles and birds, Archaeopteryx lithographica, it should be remembered that those discoveries were not strictly predicted, as though the discoveries definitely would happen. &nbsp;They are indeed consistent with certain theories, and they offer evidence powerfully supporting those theories; but the theories themselves would not be put into doubt solely if those discoveries had not been made.</p><p>

				<p><strong>Authority is irrelevant<p>Sorry to be pugnacious. I looked at your Random Thoughts blog and can't discern your credentials or profession.<p>
I have a Bachelor's degree in Mechanical Engineering, a Master's degree in Environmental Engineering (Air Pollution Option), and over 20 years of experience in environmental and energy research (and the design and analysis of advanced coal-fired, nuclear, and waste-to-energy plants).<p>
From the web:<p>
engineer: &nbsp;a person who uses scientific knowledge to solve practical problems<p>
It's just that when someone makes claims like you have, I'd sort of like to know what authority backs those up.<p>
In science, what "authority" a person has is irrelevant. <p>
Here is my Long Bets prediction #194:<p>
<a href="http://www.longbets.org/194" rel="nofollow">Long Bet #194, economic growth in the 21st century<p>
In it, I note that Dr. Robert E. Lucas Jr. (who just happens to have a frickin' Nobel Prize in Economics...related to growth theory, to boot) predicts that world per capita GDP will decelerate from approximately 3.1 percent per year at the beginning of the century to 2.3 percent per year at the end of the century, ending with a per-capita GDP of $94,000 (year 2000$). &nbsp;I claim that he is not merely wrong, he is spectacularly wrong (low by a factor of 100). &nbsp;Further, I claim that economic growth will <strong>accelerate, not decelerate.<p>
Now, either Dr. Lucas is wrong, or I am. &nbsp;(Or perhaps, as some of you seem to be thinking/dreaming, environmental problems will cause a complete collapse of the world economy.) &nbsp;But if he is wrong (and I don't think it will take more than 10-20 years to see that he is), then his Nobel Prize will not have helped him. &nbsp;Science is about who is right and who is wrong. &nbsp;Authority is a matter for religion, not science. <p>
P.S. &nbsp;The reason Dr. Lucas will be wrong is that, at least as of the year 2000, he had apparently never read Ray Kurzweil. &nbsp;Or else he hadn't thought about the implications of Ray Kurzweil's predictions (for the progress of computers relative to the human brain) on economic growth. &nbsp;So it's a similar situation to that New Yorker review mentioned earlier, in that an expert in one field does not necessarily keep up with developments in other fields that may be critically important to his own field.<p>
P.P.S. &nbsp;Of course, even if Dr. Lucas is wrong on this one issue (and I think he will be), he's still got the Nobel Prize. &nbsp;;-)

				<p><strong>Authority is irrelevant<p>Sorry to be pugnacious. I looked at your Random Thoughts blog and can't discern your credentials or profession.<p>
I have a Bachelor's degree in Mechanical Engineering, a Master's degree in Environmental Engineering (Air Pollution Option), and over 20 years of experience in environmental and energy research (and the design and analysis of advanced coal-fired, nuclear, and waste-to-energy plants).<p>
From the web:<p>
engineer: &nbsp;a person who uses scientific knowledge to solve practical problems<p>
It's just that when someone makes claims like you have, I'd sort of like to know what authority backs those up.<p>
In science, what "authority" a person has is irrelevant. <p>
Here is my Long Bets prediction #194:<p>
<a href="http://www.longbets.org/194" rel="nofollow">Long Bet #194, economic growth in the 21st century<p>
In it, I note that Dr. Robert E. Lucas Jr. (who just happens to have a frickin' Nobel Prize in Economics...related to growth theory, to boot) predicts that world per capita GDP will decelerate from approximately 3.1 percent per year at the beginning of the century to 2.3 percent per year at the end of the century, ending with a per-capita GDP of $94,000 (year 2000$). &nbsp;I claim that he is not merely wrong, he is spectacularly wrong (low by a factor of 100). &nbsp;Further, I claim that economic growth will <strong>accelerate, not decelerate.<p>

				<p><strong>Bait and switch or red herring?</strong></p><p>Mark, I think you've just demonstrated that the definitions of freedom (or (free)dom) you have at your disposal are multiple and relative, not singular and absolute as your post suggests, and those which are relevant to your argument are, yes, largely ideologically based. For example, I think you'd find it hard to find consensus that "an absolute right of property ownership" (primary methodology of your first link) is an objective measure of human freedom. Your second link with its emphasis on political and civil liberties is more mainstream but appears to display no plausible connection with your original contentious hypothesis. </p><p>
Not that this matters very much as that hypothesis is in itself entirely circular and self-referential. As a reminder:</p><p>
"Economic growth is caused by (free) human minds. &nbsp;Therefore, the more (free) human minds--or their computer equivalents--that exist, the greater will be the rate of economic growth."</p><p>
In other words, "economic growth is generated by those individuals and machines which generate economic growth. The more of them there are, the more of it there will be." Falsifiable? Maybe. Worth the trouble? Not for the purposes of an intelligent discussion of how much economic growth is good for us (as opposed to how much of it can possibly be made to happen). Sorry - looks like just one more example of an ideologically-inspired economistical non-contribution to addressing the most critical environmental issue in human history.

<p>The true meaning of life is to plant trees, under whose shade you do not expect to sit.</p></p>

				<p><strong>&quot;authority&quot;</strong></p><p>Mark Bahner makes this false and unhelpful distinction:</p><p>

Mark apparently fails to understand the many, complex ways in which we use the term "authority."</p><p>
Questions of authority arise in most, if not all, human relationships, at one point or another. &nbsp;Something so simple and every-day as the kind of friendly, cooperative conversations that we engage in could not take place, without our implicitly agreeing that sometimes it is right to assert authoritatively, sometimes to acquiesce.</p><p>
"Religion" is a royal red herring, thrown out to draw off people who suffer from ignorant prejudices. &nbsp;The world is full of all kinds of religions, religious practices and religious behaviors, reflecting all kinds of general human behaviors and attitudes, for better or worse. &nbsp;By no means do all religions exhibit the hierarchical, obscurantist assertion of private revelation that is found in certain historical forms of Judaism, Christianity and Islam. &nbsp;Nor is it fair to charge all Jews, Christians and Muslims with obscurantism, or craven acquiescence to hierarchs, or uncritical and exclusivist devotion to revealed texts.</p><p>

				<p><strong>Mark, engineers...</strong></p><p>...don't usually design machines with the idea that a part of that machine will somehow become 100 times more efficient in X amount of time. &nbsp;In other words, you don't go into a design meeting with a box at a crucial stage of the machinery, and say, "I don't know what this is now, but I'm sure that it will work wonderfully in a couple of years". &nbsp;You would be laughed out of the room. &nbsp;</p><p>
The same applies to the extremely complex machinery known as the biosphere and global economy. &nbsp;We have to work with what we have now, not what may be. &nbsp;My father was engaged in fusion research for 30 years, and while maybe a solution to that problem is "right around the corner", it could easily be another 30 years before anything comes of it. You don't know. &nbsp;We've been using the internal combustion engine for over 100 years, even though the only reason it survived into the 20th century, much less the 21st, is because of the miraculous properties of oil. </p><p>
So I'm sure you're a fine engineer, just try to let the two parts of your brain talk to each other.</p>

				<p><strong>Ah yes, &quot;economic freedom&quot;</strong></p><p>For the wealthiest, it means the ability to exploit others as mere receptacles of labor-power.</p><p>
For the relatively well-off, it's the consolation prize of a consumer lifestyle as compensation for a life working meaninglessly in the circulation sphere. &nbsp;Go, sports teams!</p><p>
For the bottom 40%, it means the "right" to leverage nothing into nothing, since said 40% has only labor power at too low a market value to count for much beyond mere survival.

				<p><strong>Mark B. (and anyone who has the time to read!)<p>Since caniscandida covered the issue of authority eloquently, I will only say ditto!<p>
But it seems you put a lot of weight into the authority of Ray Kurzweil. On the issue of whether machines will one day be as intelligent as humans (or more so in Ray's estimation) I can only say that after 20 years of <a href="http://faculty.washington.edu/gmobus/AdaptiveAgents/" rel="nofollow">researching this area with hands-on demonstrations of what I call a <a href="http://faculty.washington.edu/gmobus/AdaptiveAgents/mavric.html" rel="nofollow">'moronic snail brain' my own opinion is that Ray and Hans Morovec ("Mind Children") are overly optimistic about what computers can and will be able to do relative to the processing capabilities of brains. <p>
As to the issue of wealth creation and energy, my own contention is that wealth comes from the capture and use of free energy. It is true that it is the intelligence of the human mind that organizes material into tools that help redirect energy flows into human-valued useful work. But I also think we make too much of the notion that engineering is strictly intentional. The development of technology actually seems to fall into the category of evolutionary processes. What humans are gifted at is 'affordance' the ability to recognize a usefulness of an object and a co-opting of that object to achieve a desired objective. Later observations of how an object might be refined to achieve greater effectiveness or efficiency and intentional modification follow.<p>
In other words, we are really just muddling through it all. Where we excel is doing a lot of muddling in parallel (and that is the only argument I allow regarding the number of people - the so-called critical mass). Then natural-like selection (the market) takes over to determine which muddling results will take hold.<p>
Our problem is that we have no real far-sightedness regarding the long-term impacts of our short-term selections. Once upon a time cars seemed like a really good idea. And they were, to a point. But no one had the foresight to see what could go wrong when so many people bought and drove cars for so many miles. We humans have very little long-term judgment capability -- in other words, wisdom. Hence the muddling may progress us technologically, but unless, as Jon points out, it is coupled with the environment (and I see you have some experience in this area) and the trade-offs are noted and optimized for the long haul, it will be our undoing. I think of yeast growing in a sugar-rich environment, going wild, reproducing like crazy, and all the while churning out that most savory of fluids - ethanol. Its a waste product for yeast. But in a closed bottle with no escape it just keeps building up until it kills the yeast cells. &nbsp;It may be good (in a sense) for us but the yeast are dead.<p>
Our technologies are also the source of our non-biological wastes. These are building up at an exponential pace. What else should we expect from this scenario? Some magic technology - like super-human computers - that will thwart those nasty laws of nature and let us go on forever growing in mass, growing in junk, and depleting the natural world in order to achieve that growth?<p>

				<p><strong>bounded rationality</strong></p><p>Humans, as individuals, are imperfect. &nbsp;Human institutions, as a natural result, are imperfect. &nbsp;Science is nice because its central framework is designed to compensate for a variety of our flaws. &nbsp;It is supposed to compensate for argument from authority as well as bad logic, bad data, etc., etc.</p><p>
Critics of science like to focus on the errors, the cheats, the times science has lost its way ... but you know, at least science is trying.</p><p>
To return to the theme of this, I think hard science tries harder, and that there is less self-deception there than in the more "social" sciences ... but as I link above, there are whole (good) books on that.</p>

				<p><strong>I'm not sure it's self-deception</strong></p><p>I think hard science tries harder, and that there is less self-deception there than in the more "social" sciences</p><p>
Deception in the social science serves a purpose, and that purpose isn't self-deception. &nbsp;Social scientists can operationalize anything, make up relationships in any arbitrary way (using chi-squared if necessary to force the statistics into place), or start with any fallacious notions they care to name, in order to justify whatever social order they think will be good for the rest of us. &nbsp;It's propaganda, then.</p><p>
On this thread the big mathematical manipulation is "GDP," which is in fact a sum of prices, which are in themselves the measurement of no real material entities but rather a set of relationships between buyers and sellers as regards their fetishism of commodities.</p><p>
The purveyors of "GDP" would have you believe that a high-intensity, high-consumption lifestyle would be better than a low-intensity, low-consumption lifestyle because the former generates more "GDP." &nbsp;Myself, I'd choose the latter, as being healthier. &nbsp;</p><p>
The most arbitrary concept I've seen in this thread is that of "economic freedom," defined as the freedom of the rich to dominate the rest of us. &nbsp;Everyone's "economic freedom" is of course the freedom to leverage what they've got, but "economic slavery" (the fate of those of us with nothing that would attract the attention of the all-sacred market) isn't something measured by the purveyors of "economic freedom," who simply look at the rights of the possessors of capital to penetrate markets, without heed to social context.</p><p>
Imagine a similar concept: "military freedom," defined as the right of militaries to conduct war wherever they so choose. &nbsp;Would that be a fun use of brainpower? &nbsp;</p><p>
Thus my argument that one can have all of the brainpower in the world to devote to a problem, yet be completely stymied by adherence to the wrong initial premises.

				<p><strong>Re:  Ray Kurzweil and pollution trends</strong></p><p>But it seems you put a lot of weight into the authority of Ray Kurzweil.</p><p>
I put no weight on the authority of Ray Kurzweil. &nbsp;I've read large parts of a couple of his books (The Age of Spiritual Machines and The Singularity is Near) and many of his Internet articles or debates. &nbsp;It's his detailed research that impresses me, not who he is. &nbsp;I'm persuaded by his evidence, not his authority. &nbsp;</p><p>
As to the issue of wealth creation and energy, my own contention is that wealth comes from the capture and use of free energy.</p><p>
Again, look at North Korea vs South Korea. &nbsp;The former East Germany vs the former West Germany. &nbsp;Taiwan vs Mainland China (or Mainland China vs Hong Kong). &nbsp;One say that South Korea, West Germany, Taiwan, and Hong Kong had better "capture and use of free energy" (although I'm not even sure what that means). &nbsp;But could you PREDICT that they would have that better use? &nbsp;What is <strong>predictive</strong> is that South Korea, West Germany, Taiwan, and Hong Kong all had more economic freedom than their counterparts. &nbsp;</p><p>
It's obvious that this simple fact hurts everyone here, but it's still a simple fact. &nbsp;Free human minds (especially economically free human minds) are what create wealth.</p><p>
Our technologies are also the source of our non-biological wastes. These are building up at an exponential pace.</p><p>
This is simply not true. &nbsp;Both air and water pollution in the U.S. have significantly <strong>declined</strong> in the last 3 decades. &nbsp;They have not increased...let alone increased "exponentially."</p><p>
What else should we expect from this scenario?</p><p>
Your "scenario" is just that...it has nothing to do with present trends. &nbsp;Again, air pollution and water pollution in the U.S. have declined (significantly) in the last 3 decades.

I guess I should be charitable right before Christmas, but it's always kinda funny to me how religious people go ballistic, and say completely loony things, when their religious beliefs are confronted with conflicting scientific evidence.

Jesus was a freemarketeerian? &nbsp;Sure, why not. &nbsp;That's fairly close to the Bushco religion.</p><p>
Gaaawd gave the earth to corporations to add to their bottomline and thus expand his own gaaawd given freedom to heathen nations (only with valuable minerals or oil under them though).</p><p>
Gaaawd speaks through your fearless leader. &nbsp;He said that at an amish community meeting during the last appointment (don't call it an election)cycle.

				<p><strong>common sense predictions</strong></p><p>&nbsp; Everything is connected. &nbsp;economists make their predictions by disconnecting human activity from the eco-sphere. &nbsp;That's why they come up with these overly rosy predictions of continued economic growth. &nbsp;</p><p>
&nbsp; &nbsp;Let's inject a little common sense into this picture. &nbsp;At the present rate of fishing, there will be nothing left within fifty years. &nbsp;That means a lot of people are going to go hungry. &nbsp;</p><p>
&nbsp; &nbsp; But what about fish farms? The problem is that those fish have to be fed too. &nbsp;Either you get the feed from wild fish or from agriculture. &nbsp;If we run out of fish then the first option is out. &nbsp;If we grow the feed then we are competing for land use with food for humans.</p><p>
&nbsp; &nbsp; But global warming will lead to bigger more extended droughts which means more land, especially in the tropics is going to turn from productive farmland into desert. &nbsp;Canada and Russia may be able to increase food production because they are far enough north. &nbsp;But what happens to all the people in the tropics? &nbsp;The refugee problem will cause wars and political instability. &nbsp;Think Sudan and Rwanda on a global scale. &nbsp;</p><p>
&nbsp; &nbsp; There was one economist who did see the connections - &nbsp;Malthus. &nbsp;He didn't take into account technological change so he has been proven wrong for the last two hundred years. &nbsp; &nbsp;Technology has prolonged human life and created untold efficiencies, &nbsp;leading to economic growth and higher standards of living. </p><p>
&nbsp; &nbsp;The question is, can technology keep producing this miracle of increasing productivity? &nbsp;The common sense answer is no. We cannot keep extracting resources unsustainably and damaging the environment without some kind of payback down the road. &nbsp;</p><p>
&nbsp; &nbsp; We don't know when that day will come. &nbsp;Global warming appears to be showing us that it may be sooner than we think. Common sense tells us when we don't have any fish in the sea or enough crops to eat that all the computing power in the world isn't going to make any difference to the outcome. &nbsp;</p>

				<p><strong>Economic predictions and &quot;common sense&quot;</strong></p><p>Economists make their predictions by disconnecting human activity from the eco-sphere. &nbsp;That's why they come up with these overly rosy predictions of continued economic growth.</p><p>
Actually, 99% of economists <strong>underestimate</strong> the likely growth in the 21st century. &nbsp;Averaged over the century, the world economy will likely grow by over 7 percent per year (adjusted for inflation). &nbsp;Most of the growth over 7 percent per year will probably come after 2030, however. &nbsp;This is because most economists don't appreciate the likely economic impacts of computers equaling and then vastly exceeding the capabilities of the human mind.</p><p>
Let's inject a little common sense into this picture. &nbsp;At the present rate of fishing, there will be nothing left within fifty years. &nbsp;That means a lot of people are going to go hungry.</p><p>
No, that's wrong on several accounts. &nbsp;Most importantly, food from the sea is not presently a signficant source of calories for homosapiens. &nbsp;Worldwide, approximately 5 percent of protein consumed by humans comes from fish.</p><p>
But global warming will lead to bigger more extended droughts which means more land, especially in the tropics is going to turn from productive farmland into desert.</p><p>
What productive farmland in the tropics do you think will turn into desert?</p><p>
There was one economist who did see the connections - &nbsp;Malthus. &nbsp;He didn't take into account technological change so he has been proven wrong for the last two hundred years.</p><p>
Yes, he's been proven wrong. &nbsp;So why mention him?</p><p>
The question is, can technology keep producing this miracle of increasing productivity? &nbsp;The common sense answer is no.</p><p>
No, the commonsense answer is "yes." &nbsp;You've just noted that Malthus has been wrong for more than 200 years. &nbsp;The commonsense conclusion is that he'll be wrong for the next 200 years also. &nbsp;Especially considering the current trends in food production, medicine, and computers. &nbsp;(Not to mention energy technologies such as photovoltaics.)

Real global growth averaged 4.9 percent a year during the Golden Age of national Keynesianism (1950-1973). It was 3.4 percent between 1974 and 1979; 3.3 percent in the 1980s; and only 2.3 percent in the 1990s, the decade with the slowest growth since World War II.<p>
And now we are to expect over 7% per year?
