What happens if each of those experts feels entitled, even obligated, to lie just a little, to shade his conclusions to strengthen the support they provide for what he believes is the right conclusion? Each of them then interprets the work of all the others as providing more support for that conclusion than it really does. The result might be that they end up biasing their results in support of the wrong conclusion—which each of them believes is right on the basis of the lies of all the others.
That is one of the reasons I am not greatly impressed by the supposed scientific consensus in favor of Catastrophic Anthropogenic Global Warming.

As I am fond of saying, it works like a stock market bubble. There is no need to posit a conspiracy. David Friedman’s view that this is a matter of a build up of many little lies rather than a few big ones is a more realistic as well as a more charitable picture of the mechanism at work.
I am yet more charitable than Professor Friedman. Though I completely agree with him that there are almost certainly many scientists shading their conclusions, it might well be the case that they are not doing so consciously at all. All it would take is for a lot of people with jobs to keep and mortgages to pay each to see which side their bread is buttered when the time comes round to apply for grants. As the American socialist author Upton Sinclair put it, “It is difficult to get a man to understand something, when his salary depends on his not understanding it.” On the unbuttered side of the bread, when a scientist observes that colleagues who raise doubts suffer for it, she would be acting much like the rest of humanity if she, while never aware of feeling fear, somehow finds herself more comfortable out of the intellectual proximity of these pariahs.
In a way the Rosetta scientists had it easy. All they had to do was hit a moving target half a billion kilometres away. Succeed or fail, there is no kidding yourself and no kidding others. Twenty-eight minutes later you and the world will know.
ADDED LATER: Fraser Orr comments:
“The answer to the CAGW people is simple: make a prediction that is falsifiable and can be measured in a reasonable length of time. Give me an example of a significant result where you predicted the future and it came true. Explain why your last fifteen years of prediction have been completely wrong, and if you have a wild ass explanation of something you didn’t factor in, give us a reason to believe that you didn’t forget something else.”

Normally it’s rather difficult to get the news media to lose their shit like a bunch of screeching schoolkids over a story like, “Defense Manufacturer Offers New Product That Makes Incremental Advances on Existing, Widely-Used Technology.” But fortunately for Israeli defense manufacturer Rafael, the maker of the Iron Dome short-range air defense system, reporters don’t always understand what it is they’re reporting on.

VICE has a very interesting report, looking at at how the US military is adjusting to the astonishingly rapid proliferation and deployment of cheap drone technology. Faced with using multi million dollar weapons platforms firing munitions costing hundreds of thousands of dollars against these things, they are seeking more feasible ways to counter air threats costing thousands or even mere hundreds of dollars. And the threat is not hypothetical: even the daesh Islamic State claims fairly plausibly to be using cheap reconnaissance drones right now, and Hezbollah appears to have fairly sophisticated armed drones (fast forward to 1:25 or thereabouts to see the boom and hear the invocations to Admiral Ackbar or whatever). We really are entering a new era not just commercially but also militarily.
Great confidence is being expressed about how robot cars are about to change the world. Robot cars, says a typical headline that Google (one of the prime movers in this new technology) has just today alerted me to, may be coming sooner than you think. But doubts are also being expressed:
A good technology demonstration so wows you with what the product can do that you might forget to ask about what it can’t.
Case in point: Google’s self-driving car. There is a surprisingly long list of the things the car can’t do, like avoid potholes or operate in heavy rain or snow.
Yet a consensus has emerged among many technologists, policymakers, and journalists that Google has essentially solved – or is on the verge of solving – all of the major issues involved with robotic driving.
“Essentially”. That’s a word that often means “not”. And “on the verge of” often signals a problem that turns out to be hideously intractable, as year after year passes with nobody any nearer to a definitive answer. I seem to recall an entire British high speed train project being abandoned because they just could not make the tilting of the carriages work perfectly. It worked okay, but okay wasn’t good enough. It had to be perfect, and perfection proved elusive. Here is what wikipedia says about that, for whatever wikipedia may be worth when reporting a story that remains controversial.
Even that constantly repeated refrain about how robot cars are coming “sooner than you think” is, if you think some more, an acknowledgement from robot car boosters that there are actually widespread doubts out there in the regular, non-techy world about how well these devices really will work, and how completely, above all how quickly, all the problems that they will face have really been and will really be solved. Yes, the techies will eventually get their robot cars working, probably. But for a few more years yet, there will surely be a nasty little clutch both of known unknowns and of unknown unknowns to deal with, all of which will have to be thoroughly dealt with. Crucially, such problems will all have to be solved. If robot cars get the go-ahead and work flawlessly for two months, followed by a lurid catastrophe like something out of a disaster movie, when a bunch of robot cars all follow each other into a swamp or over a cliff, or just run amuck and kill dozens or even hundreds in one catastrophe like in a plane crash, then their introduction will be judged a failure rather than given nine out of ten for technical accomplishment and an A plus for effort.
This strikes me as a lot more immediately promising:

Imagine audio and video bugs get better and better. Maybe in the form of tiny physical cameras, maybe as viruses that will eventually succeed in penetrating any computer, phone or similar device, maybe as some kind of broadcast or field. There is parallel progress in the science of searching through audio-visual records. Eventually every house, every room, every human body is bugged – saturated with bugs. Of course most of the time no one is interested in you. But if ever you become interesting, they can watch you, not just now, but at any time going back years. What you were doing on any given day. Every time you sang along to your ipod, had sex, mentioned the word “government”. But “they” is not just the government; it is anyone.
Bishop Hill has linked to what he calls a “magnificent” polemical book review by a man from the other camp, Martin W. Lewis, who speaks from the conviction that “anthropogenic climate change is a huge problem that demands determined action.”
Magnificent it is. Magnificently funny, as in the bit about the pussycat apocalypse; and magnificently right about what is wrong with The Collapse of Western Civilization: A View from the Future by Naomi Oreskes and Erik M. Conway.
Oreskes and Conway’s authoritarian inclinations are seemingly linked to their contempt for the West, which they identify with a dangerous devotion to personal freedom. The most telling passage to this effect is found in the authors’ interview, where Erik Conway states:
To me, [The Collapse of Western Civilization] is hopeful. There will be a future for humanity, even if one no longer dominated by “Western Culture.”
No matter that Oreskes and Conway see every last person in Africa perishing, they still apparently find such a scenario promising as long as Western Culture perishes in the process.
As noted at the beginning of this essay, tens of millions of people have reached the conclusion that anthropogenic climate change is a giant hoax perpetuated by corrupt scientific and journalistic establishments. In their previous book, Merchants of Doubt, Oreskes and Conway attribute such benighted views to the money and machinations of oil companies and other organizations with financial interests in the status quo. While I would not deny that such factors play a role, they do not provide a full account. Of particular significance are the writings of green extremists such as Oreskes and Conway themselves. By putting forth grotesque exaggerations, by engaging in misleading reportage, and by embracing authoritarian if not totalitarian politics, they discredit their own cause. The Collapse of Western Civilization, in short, reads as if it were part of a great conspiracy, one that that seemingly rests on an insincere approach to evidence and argumentation.
Martin Lewis also highlights an area of particular interest to me. Apparently Oreskes and Conway disapprove of those “overwhelmingly male” * physical scientists who concentrate on narrow “physical constituents and processes”, “to the neglect of biological and social realms.” Lewis quotes Oreskes and Conway as going so far as to regard statistical significance as an outmoded concept. Lewis writes further,
Although many of the key scientific questions of the day do indeed demand, as Oreskes and Conway write, an “understanding of the crucial interactions between physical, biological, and social realms,” it is equally imperative to recognize that most do not. Most of the issues addressed by chemists, physicists, and geologists have nothing to do with the social realm, and must be examined through a “reductionistic” lens if they are to be approached scientifically. To insist instead that they must be framed in a socio-biological context is to reject the methods of science at a fundamental level. Such a tactic risks reviving the intellectual atmosphere that led the Soviet Union to the disaster of ideologically contaminated research known as Lysenkoism. In the final analysis, the denial of science encountered in The Collapse of Western Civilization thus runs much deeper than that found among even the most determined climate-change skeptics, as it pivots on much more basic epistemological and methodological issues.
This passage describes one type of catastrophist error about science very well. I would like to point out, however, that it is not the only type. There are also catastrophists who propagate, some knowingly, some not, the opposite error. I refer to those who, rather than dismissing the Gradgrind-like definiteness of physics and chemistry, seek to borrow their reputation for precision and certainty in order to cloak the naked fact that no such certainty is even close to being achieved in the study and modelling of of climate systems.
*And boy, or rather girl, does that irrelevant slighting reference to the scientists’ presumed gender tell you nearly everything you need to know about Oreskes and Conway’s attitude to science.
Optimistic science fiction does not create a belief in technological progress. It reflects it. Stephenson and Thiel are making a big mistake when they propose a vision of the good future that dismisses the everyday pleasures of ordinary people – that, in short, leaves out consumers. This perspective is particularly odd coming from a fiction writer and a businessman whose professional work demonstrates a keen sense of what people will buy. People are justifiably wary of grandiose plans that impose major costs on those who won’t directly reap their benefits. They’re even more wary if they believe that the changes of the past have brought only hardship and destruction. If Stephenson wants to make people more optimistic about the future and more likely to undertake difficult technological challenges, he shouldn’t waste his time writing short stories about two-kilometer-high towers.

I rececntly ordered a water circulating heater for sous vide cooking. I do not like cooking all that much, but the controllability and repeatability of sous vide, along with the opportunity to play with a new gadget, appeal to my not-so-inner geek. To make the most of it, I ordered a copy of Modernist Cuisine at Home. It is a home version of the original Modernist Cuisine book that comprises six volumes and 2,400 pages and deconstructs the science of cooking. It is part of the molecular gastronomy movement in cooking, an attempt to make cooking more science-y. This appeals to me also because normal cookbooks are oppressive: “Do this!” they say, without ever explaining why. From their random examples I am unable to build a mental model of what is going on, so I can only follow the instructions blindly and wonder why I failed. And the jargon in cookbooks is incomprehensible; I am much more likely to be able to understand a science book.
Nathan Myhrvold is a principal author of Modernist Cuisine. He was the CTO of Microsoft and later went on to found Intellectual Ventures, which buys patents and licenses then to companies who are being patent trolled, though others have accused them of patent trolling themselves. An offshoot of this is Intellectual Ventures Lab, which does research and applies for patents and contains the kitchen where the cookbook was developed.
Myhrvold is a global warming believer, though he annoyed all the right people when he appeared in a chapter in Superfreakonomics suggesting that we might reverse the effects of man-made global warming with other man-made technology, instead of by reducing carbon dioxide emissions. And he is a proponent of nuclear power as a solution. Intellectual Ventures Labs began work on a travelling wave reactor, a type of nuclear reactor that runs on U-238, which reduces the need for enriching. TerraPower is now one of many subsidiaries, and is developing the reactor.
Between this, thorium, and a host of other reactor designs, I am hopeful about the technology of nuclear power, we just need the politics to catch up. A micro nuclear reactor was proposed in Alaska but, “the project never began the mandatory, lengthy and extremely costly process of gaining approval by the Nuclear Regulatory Commission…which takes tens of millions of dollars and several years”.
Talk about ingenuity! That thing does not looks very RPG-resistant, so it very wisely has a top mounted camera so it can fire from behind cover!
But guys, it is an improvised armoured ambulance, not a ‘tank’.
