The Discovery of Global Warming
Hyperlinked History of Climate Change Science
"To a patient scientist, the unfolding greenhouse mystery is far more exciting than the plot of the best mystery novel. But it is slow reading, with new clues sometimes not appearing for several years. Impatience increases when one realizes that it is not the fate of some fictional character, but of our planet and species, which hangs in the balance as the great carbon mystery unfolds at a seemingly glacial pace." -- D. Schindler
The Evolution of Diet
Could eating like our ancestors make us healthier? Some experts say modern humans should eat from a Stone Age menu. What's on it may surprise you.
The notion that we stopped evolving in the Paleolithic period simply isn't true. Our teeth, jaws, and faces have gotten smaller, and our DNA has changed since the invention of agriculture. "Are humans still evolving? Yes!" says geneticist Sarah Tishkoff of the University of Pennsylvania. . . . More accurately, you are what your ancestors ate. There is tremendous variation in what foods humans can thrive on, depending on genetic inheritance. Traditional diets today include the vegetarian regimen of India's Jains, the meat-intensive fare of Inuit, and the fish-heavy diet of Malaysia's Bajau people. The Nochmani of the Nicobar Islands off the coast of India get by on protein from insects. "What makes us human is our ability to find a meal in virtually any environment," says the Tsimane study co-leader Leonard. . . . In other words, there is no one ideal human diet. Aiello and Leonard say the real hallmark of being human isn't our taste for meat but our ability to adapt to many habitats - and to be able to combine many different foods to create many healthy diets. Unfortunately the modern Western diet does not appear to be one of them.

The Case against Patents
Journal of Economic Perspectives: Vol. 27 No. 1 (Winter 2013)
The case against patents can be summarized briefly: there is no empirical evidence that they serve to increase innovation and productivity, unless productivity is identified with the number of patents awarded -- which, as evidence shows, has no correlation with measured productivity. Both theory and evidence suggest that while patents can have a partial equilibrium effect of improving incentives to invent, the general equilibrium effect on innovation can be negative.
Extracting audio from visual information
Algorithm recovers speech from the vibrations of a potato-chip bag filmed through soundproof glass.
Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.Who would have thunk it?
Why Psychologists' Food Fight Matters
"Important findings" haven't been replicated, and science may have to change its ways.
The recent special issue of Social Psychology was an unprecedented collective effort by social psychologists to do just that - by altering researchers' and journal editors' incentives in order to check the robustness of some of the most talked-about findings in their own field. Any researcher who wanted to conduct a replication was invited to preregister: Before collecting any data from subjects, they would submit a proposal detailing precisely how they would repeat the original study and how they would analyze the data. Proposals would be reviewed by other researchers, including the authors of the original studies, and once approved, the study's results would be published no matter what. Preregistration of the study and analysis procedures should deter p-hacking, guaranteed publication should counteract the file drawer effect, and a requirement of large sample sizes should make it easier to detect small but statistically meaningful effects. The results were sobering. At least 10 of the 27 "important findings" in social psychology were not replicated at all. In the social priming area, only one of seven replications succeeded. . . . Caution about single studies should go both ways, though. Too often, a single original study is treated - by the media and even by many in the scientific community - as if it definitively establishes an effect. Publications like Harvard Business Review and idea conferences like TED, both major sources of "thought leadership" for managers and policymakers all over the world, emit a steady stream of these "stats and curiosities." Presumably, the HBR editors and TED organizers believe this information to be true and actionable. But most novel results should be initially regarded with some skepticism, because they too may have resulted from unreported or unnoticed methodological quirks or errors. Everyone involved should focus their attention on developing a shared evidence base that consists of robust empirical regularities - findings that replicate not just once but routinely - rather than of clever one-off curiosities.
Calm Hearts, Bad Behavior
David Kohn in The New Yorker tech elements blog.
There are several theories, but Raine tends to favor the fearlessness hypothesis, which says that some of those with L.R.H.R. remain undaunted by the threats that would keep most of us in check. When you get scared, your heart rate goes up, because your body activates to deal with the imminent hazard. By definition, people with less fear tend not to get activated in situations that others find threatening. . . . Raine's skeptics argue that L.R.H.R. and other biological factors play a relatively minor role in determining who becomes a criminal. "The evidence is pretty consistent that biological traits don't have a large effect," Robert Sampson, a social scientist at Harvard University who has studied the topic for more than two decades, told me. "Social and environmental characteristics have much more weight."
When It's Bad to Have Good Choices
Maria Konnikova in The New Yorker science blog.
Unsurprisingly, when people were asked to decide between something like an iPod and a bag of pretzels, they didn't feel particularly anxious: the choice was clear and life was good. When both choices were low in value, the emotions were similarly clear - cut. No one was particularly happy, but neither were they anxious. But when multiple highly positive options were available - a digital camera and a camcorder, say - anxiety skyrocketed, just as Lipowski had predicted. The choices between those objects that they valued most highly were both the most positive and the most anxiety - filled. The more choices they had - the study was repeated with up to six items per choice - the more anxious they felt. "When you have more good choices, you don't feel better," Shenhav says. "You just feel more anxious."

Oligarchy: a government in which a small group exercises control, especially for corrupt and selfish purposes.
Is America an Oligarchy?
After examining differences in public opinion across income groups on a wide variety of issues, the political scientists Martin Gilens, of Princeton, and Benjamin Page, of Northwestern, found that the preferences of rich people had a much bigger impact on subsequent policy decisions than the views of middle-income and poor Americans. Indeed, the opinions of lower-income groups, and the interest groups that represent them, appear to have little or no independent impact on policy.
US Is an Oligarchy Not a Democracy, says Scientific Study
The clear finding is that the U.S. is an oligarchy, no democratic country, at all. American democracy is a sham, no matter how much it's pumped by the oligarchs who run the country (and who control the nation's "news" media). The U.S., in other words, is basically similar to Russia or most other dubious "electoral" "democratic" countries. We weren't formerly, but we clearly are now. Today, after this exhaustive analysis of the data, "the preferences of the average American appear to have only a minuscule, near-zero, statistically non-significant impact upon public policy."
How to Become an Oligarch

If the new graduate in your life has the connections to join a very large brand-name private-equity fund, the path to immense wealth, political influence, or even power becomes much clearer. Without such initial connections, however, it is very unlikely that he or she will become an oligarch. But you knew that already.
End the Export-Import Bank and Other Forms of 'Crapitalism'
It's crapitalism when politicians give your tax money and other special privileges to businesses that are run by their cronies.
Voters assume government handouts go to people who need help. But they usually don't. Most government handouts go to the middle class and the rich. Government has no business handing out loan guarantees to companies. Corporations can pay their own way. The Agriculture Department's Market Access Program gives millions of dollars to affluent groups like the Pet Food Institute, the Wine Institute, Sunkist, and Welch Foods. In return, politicians get campaign contributions. It's disgusting crapitalism.

To change attitudes, don't argue -- agree, extremely
Contradicting people's beliefs often doesn't change them, but agreeing with them just might.
Researchers found that showing people extreme versions of ideas that confirmed -- not contradicted -- their opinions on a deeply divisive issue actually caused them to reconsider their stance and become more receptive to other points of view. The scientists attribute this to the fact that the new information caused people to see their views as irrational or absurd, according to a study published Monday in the Proceedings of the National Academy of Sciences.
"For example, the fact that they are the most moral society in the world is one of the most basic beliefs of Israeli society," Halperin said. So when the researchers showed participants a video that claimed Israel should continue the conflict so that its citizens could continue to feel moral, people reacted angrily.

Sometimes, Early Birds Are Too Early
Procrastination Can Be A Positive Thing - Matt Richtel, NYT
They could pick up a bucket near the start of the alley and carry it to the end, or they could pick up a different bucket that was closer to the end of the alley, walk a few steps and put it down.
In particular, Dr. Rosenbaum said, people are seeking ways to limit the burden to their "working memory," a critical but highly limited mental resource that people use to perform immediate tasks. By picking up the bucket earlier, the subjects were eliminating the need to remember to do it later. In essence, they were freeing their brains to focus on other potential tasks.
The Trouble With Brain Science
An example is the discovery of DNA, which allowed us to understand how genetic information could be represented and replicated in a physical structure. In one stroke, this bridge transformed biology from a mystery - in which the physical basis of life was almost entirely unknown - into a tractable if challenging set of problems, such as sequencing genes, working out the proteins that they encode and discerning the circumstances that govern their distribution in the body.
Neuroscience awaits a similar breakthrough. We know that there must be some lawful relation between assemblies of neurons and the elements of thought, but we are currently at a loss to describe those laws. We don't know, for example, whether our memories for individual words inhere in individual neurons or in sets of neurons, or in what way sets of neurons might underwrite our memories for words, if in fact they do.
How Much Do Our Genes Influence Our Political Beliefs?
Why do so many poor, working-class and lower-middle-class whites - many of them dependent for survival on government programs - vote for Republicans?
Identical twins are more likely than fraternal twins to share traditional values with their twin siblings, suggesting a biological link on cultural outlook.
The significance of the different correlations for identical and fraternal twins, Ludeke added, is that "when we see identical twins who are this similar, while fraternal twins are much less similar, we have a good indication that genes account for some of the difference between people for the trait in question."

The Curse of Smart People
Smart people have a problem, especially (although not only) when you put them in large groups. That problem is an ability to convincingly rationalize nearly anything. Here's the problem. Logic is a pretty powerful tool, but it only works if you give it good input. As the famous computer science maxim says, "garbage in, garbage out." If you know all the constraints and weights - with perfect precision - then you can use logic to find the perfect answer. But when you don't, which is always, there's a pretty good chance your logic will lead you very, very far astray.

How often do economists commit misconduct?
This study reports the results of a survey of professional, mostly academic economists about their research norms and scientific misbehavior. Behavior such as data fabrication or plagiarism are (almost) unanimously rejected and admitted by less than 4% of participants. Research practices that are often considered "questionable," e.g., strategic behavior while analyzing results or in the publication process, are rejected by at least 60%. Despite their low justifiability, these behaviors are widespread. Ninety-four percent report having engaged in at least one unaccepted research practice. Surveyed economists perceive strong pressure to publish. The level of justifiability assigned to different misdemeanors does not increase with the perception of pressure. However, perceived pressure is found to be positively related to the admission of being involved in several unaccepted research practices. Although the results cannot prove causality, they are consistent with the notion that the "publish or perish" culture motivates researchers to violate research norms.

Antioxidant vitamins don't stress us like plants do - and don't have their beneficial effect.
Warding off the diseases of aging is certainly a worthwhile pursuit. But evidence has mounted to suggest that antioxidant vitamin supplements, long assumed to improve health, are ineffectual. Fruits and vegetables are indeed healthful but not necessarily because they shield you from oxidative stress. In fact, they may improve health for quite the opposite reason: They stress you. That stress comes courtesy of trace amounts of naturally occurring pesticides and anti-grazing compounds. You already know these substances as the hot flavors in spices, the mouth-puckering tannins in wines, or the stink of Brussels sprouts. They are the antibacterials, antifungals, and grazing deterrents of the plant world. In the right amount, these slightly noxious substances, which help plants survive, may leave you stronger. Parallel studies, meanwhile, have undercut decades-old assumptions about the dangers of free radicals. Rather than killing us, these volatile molecules, in the right amount, may improve our health. Our quest to neutralize them with antioxidant supplements may be doing more harm than good.[Added 07/19/2014]

Thomas Piketty's book Capital in the 21st Century
is being discussed everywhere

- Thomas Piketty - Taking on Adam Smith (and Karl Marx) (New York Times)
- Piketty findings undercut by errors -- But see next link Chris Giles in the Financial Times
- Piketty Rejects "Ridiculous" Allegations of Data Flaws Thomas Piketty rejected allegations that data behind his best-selling book on inequality are flawed as fellow economists spoke up in his defense.
- Are There Problems with Piketty's Data? Of Course A fairly balanced discussion of the criticism, from National Review!
- A Plea for Calm in the Debate Over 'Capital' A nice summary of the arguments for both sides.
Be Skeptical of Both Piketty And His Skeptics
Statistics maven Nate Silver gives some broad perspective
about data collection, publication and analysis.
- The Economist Was a Rock Star (The New Republic) Thomas Piketty isn't just a brilliant economist; he's a fantastic storyteller
- The Conservative Case Against Piketty Is Shockingly Weak (The New Republic)
- Living with Inequality (Reason.com) Has Thomas Piketty really found "the central contradiction of capitalism"?
- Thomas Piketty's Path to Poverty For the Masses (Real Clear Markets)
- Inequality and the Fate of Capitalism (National Review)
- Tyler Cowen's book review in Foreign Affairs Why a Global Tax on Wealth Won't End Inequality
The closest thing to a solution is to remain appropriately skeptical, perhaps especially when the research finding is agreeable to you.
We need a new conversation about inequality
Democrats are scared of class. But issues like inequality are why liberals exist, and talk can't be left to elites.
When President Obama declared in December that gross inequality is the "defining challenge of our time," he was right, and resoundingly so. As is his habit, however, he quickly backed away from the idea at the urging of pollsters and various Democratic grandees.

Income Growth and Income Inequality: The Facts May Surprise You
Gary Burtless at The Brookings Institution offers a slightly contrarian point of view.
CBO's newest estimates confirm the long-term trend toward greater inequality, driven mainly by turbo-charged gains in market income at the very top of the distribution. The market incomes of the top 1% are extraordinarily cyclical, however. They soar in economic expansions and plunge in recessions. Income changes since 2007 fit this pattern. What many observers miss, however, is the success of the nation's tax and transfer systems in protecting low- and middle-income Americans against the full effects of a depressed economy. As a result of these programs, the spendable incomes of poor and middle class families have been better insulated against recession-driven losses than the incomes of Americans in the top 1%. As the CBO statistics demonstrate, incomes in the middle and at the bottom of the distribution have fared better since 2000 than incomes at the very top.
Income Inequality in America - Fact and Fiction
The extent of inequality differs with the measure used.
This pre-tax, pre-transfer measure of inequality is, however, misleading because it fails to properly measure well-being. Upper-income individuals cannot spend the money that is taken away in taxes, so it gives them no benefit (other than, perhaps, higher social status). On the other hand, lower-income individuals clearly benefit from more spending power with, among others, the Supplemental Nutrition Assistance Program, Medicaid, housing vouchers, and unemployment insurance. As such, it would be inaccurate not to include the latter in measures of their well-being.[Added 07/14/2014]

Social Mobility Hasn't Fallen: What It Means and Doesn't Mean
Our estimates are still too imprecise to rule out modest trends in either direction. For the most part, though, our results for the cohorts born between 1952 and 1975 suggest that intergenerational income mobility in the United States has not changed dramatically over the past two decades.and
We find that all of these rank-based measures of intergenerational mobility have not changed significantly over time. For example, the probability that a child reaches the top fifth of the income distribution given parents in the bottom fifth of the income distribution is 8.4 per cent for children born in 1971, compared with nine per cent for those born in 1986.

Human Brain Limits
There is one thing that seems obvious to me but most scientists disagree. Namely that the human brain cannot understand everything about the world we live in. Not just because we haven't figured it out yet, but because our brains are a product of evolution. Since most agree that other mammals, even those with large brains, cannot understand the world as humans do, isn't it presumptuous to think some species won't come after us that makes us look similarly dumb?
So I was happy to see on Edge.org, in a response to it's question of the year for 2014: What Scientific Idea Is Ready For Retirement? by Martin Rees one of the world's leading astronomers and cosmologists:
We'll Never Hit Barriers To Scientific Understanding (NOT)
There's a widely-held presumption that our insight will deepen indefinitely -- that all scientific problems will eventually yield to attack. But I think we may need to abandon this optimism. The human intellect may hit the buffers -- even though in most fields of science, there's surely a long way to go before this happens.
And ends with,
We humans haven't changed much since our remote ancestors roamed the African savannah. Our brains evolved to cope with the human-scale environment. So it is surely remarkable that we can make sense of phenomena that confound everyday intuition: in particular, the minuscule atoms we're made of, and the vast cosmos that surrounds us.
Nonetheless -- and here I'm sticking my neck out -- maybe some aspects of reality are intrinsically beyond us, in that their comprehension would require some post-human intellect -- just as Euclidean geometry is beyond non-human primates. . . .
It would be unduly anthropocentric to believe that all of science -- and a proper concept of all aspects of reality -- is within human mental powers to grasp. Whether the really long-range future lies with organic post-humans or with intelligent machines is a matter for debate -- but either way, there will be insights into reality left for them to discover.That is just the way I see it.

METRICS, as the new laboratory is to be known for short, will connect enthusiasts of the nascent field in such corners of academia as medicine, statistics and epidemiology, with the aim of solidifying the young discipline.
The Only Way to Stop Illegal Immigration
Workplace enforcement is minimal. Fines are small. Amid all the political bellowing about the border, no one in Washington pays much attention to employers' practices.
The only way to make meaningful progress is to end the lure of employment.
Global warming: Who pressed the pause button?
The slowdown in rising temperatures over the past 15 years goes from
being unexplained to overexplained.
Gavin Schmidt and two colleagues at NASA's Goddard Institute quantify the effects of these trends in Nature Geoscience. They argue that climate models underplay the delayed and subdued solar cycle. They think the models do not fully account for the effects of pollution (specifically, nitrate pollution and indirect effects like interactions between aerosols and clouds). And they claim that the impact of volcanic activity since 2000 has been greater than previously thought. Adjusting for all this, they find that the difference between actual temperature readings and computer-generated ones largely disappears. The implication is that the solar cycle and aerosols explain much of the pause.
Big Company CEOs Just Aren't Worth What We Pay Them
A recent paper by J. Scott Armstrong of the Wharton School and Philippe Jacquart of France's EMLYON, seem to have finally established that paying top dollar simply doesn't get a better job done. And, in fact, it might actually get a worse one done.
There is no gender gap in tech salaries
New research shows that there is no statistically significant difference in earnings between male and female engineers who have the same credentials and make the same choices regarding their career.
Why Is the Merger Called Mayonnaise Loved -- & Hated -- so Deeply?
As mayonnaise has conquered the world, it has also divided its eaters. Paul Rozin, professor of food psychology at the University of Pennsylvania, says mayonnaise "splits people into likers and dislikers, with few in the middle."
The magic of mayonnaise is in the egg yolk, which contains substances that stabilize the oil and water in a mixture called an emulsion.
The experts on food aversion I spoke with generally agreed that the slimy texture of mayo is responsible for much, if not most, of the disgust people feel towards it.
The simple, sensible -- and impossible -- fix for the Internet in the USA
Look around at your home now. You don't have four different water mains coming in with only one hooked up. You don't have five different power lines waiting on the pole. You don't have three different telephone networks run down your street. You have one of each. In some places you may have a selection of power companies, but no matter which you choose, power is delivered via the same lines. You may even pick among telephone companies, but again, the service is delivered through the same physical telephone lines.
There is no reason for requiring that competing broadband Internet access providers in a market deploy their own last-mile networks. Heck, as taxpayers, we've already subsidized the Internet build-out of the United States to a massive degree. We've already paid for these networks.
Perhaps that should be the deal struck with Comcast and Time Warner Cable. Sure, go ahead and create the largest cable company in the world -- but only if you become a common carrier and allow competition throughout your network. You can play, but you must allow competitors access to your last-mile infrastructure for fixed prices, and they can compete with you fair and square. If Comcast and Time Warner squawk and say other companies don't have to do the same, perhaps we do exactly that. Fair is fair, after all.
Publishers Withdraw More than 120 Gibberish Science and Engineering Papers
The publishers Springer and IEEE are removing more than 120 papers from their subscription services after a French researcher discovered that the works were computer-generated nonsense.
Is It Normal to Hoard?
Hoarding shows us at our best, and worst.
Modern science has clearly revealed why hoarding deserves the designation of "disorder": It is reflected in physical differences in how the brain is wired. At the same time, it is something that reflects to us some of the qualities and decisions with which we all struggle: Consumerism, attachment, decision-making, time management-and, at some level, survival. I'm left wondering if it is any coincidence that it was in 2013, when society demands so much from us in each of these capacities, that hoarding has taken on full-fledged disorder status in the DSM-V handbook.
Investing's Biggest Irony: Everyone Thinks They're a Contrarian
"You never know what the American public is going to do,
but you know they will do it all at once."
- Bill Seidman
Even when everyone around you is giving an obviously wrong answer, your tendency to second-guess yourself, not want to embarrass yourself, and your natural desire to fit in can trump every bit of rationality you think you have.
Revealing the secret corruption inside PBS's news division
In recent years, this campaign has seen public television stations ignore PBS's own rules about editorial control and pre-ordained conclusions. Indeed, stations across the country have started airing programming from wealthy ultraconservative foundations and corporate interests looking to promote their political messages through the PBS brand.
Why Walking through a Doorway Makes You Forget
Why would we have a memory system set up to forget things as soon as we finish one thing and move on to another? Because we can't keep everything ready-to-hand, and most of the time the system functions beautifully. It's the failures of the system-and data from the lab-that give us a completely new idea of how the system works.
What Do You Believe In?
We readily recognize that facts are not the same things as truth. Facts are true by definition (or they wouldn't be facts), but they require analysis, understanding and interpretation to become useful and actionable, to become truth. Logically, we should decide what the facts are as objectively as we can and then interpret the facts to come to a consistent set of beliefs about them. But that's not how it usually works. We try to jam the facts into our pre-conceived notions and commitments or simply miscomprehend reality such that we accept a view, no matter how implausible, that sees a different set of alleged facts, "facts" that are used (again) to support what we already believe. Since we quite readily see poor thinking in others but fail to see it in ourselves (on account of bias blindness) and live in a highly polarized society wherein commonly accepted facts are increasingly rare, beliefs (at least the beliefs of people who disagree with us) are not generally held in high regard. ...
We are ideological creatures through-and-through. We prefer stories to data consistently, no matter how fanciful the story or how rigorous the data. It can be maddeningly difficult for us to separate fact from belief. Thus it is very dangerous business indeed to lose sight of what works in order to massage our egos, feel comforted or score ideological points. ...
I'd love to be able to act upon facts alone, of course, assuming I can come to a fair approximation of them. But facts without interpretation are still useless.
