The distinguished philosopher Thomas Nagel has spent much of his career defending an antireductionist view of mind. His new book, “Mind and Cosmos,” extends this skepticism to much of contemporary scientific inquiry, including evolutionary biology, and calls for a new scientific revolution based on teleological principles. It’s a proposal that has, unsurprisingly, been quite controversial

, they think Nagel’s insistence “that explanation and prediction are symmetrical” is an outdated one, and that his description of what a new, teleologically-oriented science would look like is insufficiently clear.

As for teleology, Sober has no problem understanding certain phenomena this way, as long as there are “causal underpinnings” for a given teleological statement. But Nagel’s position, as Sober understands it, entails “teleological explanations that are both true and causally inexplicable,” a class for which neither Sober, nor Nagel, apparently, can offer any examples. (In a strangely concessive coda, Sober does admit that his “reactions may be mired in presuppositions,” and that history may prove Nagel to be “a prophet whom naysayers such as me were unable to recognize.”)

A team of researchers walked every street in 228 census tracts around Los Angeles and New Orleans and recorded every outdoor ad they saw. Another group surveyed 2,881 residents of the same census tracts by telephone, paying them to report their height, weight and other information. After analyzing this hard-won data, the authors conclude: “For every 10 percent increase in food advertisements, the odds of being obese increased by 5 percent.” That is, areas with more outdoor food ads have a higher proportion of obese people than ones with fewer ads.

The problem is that their policy recommendations rest on a crucial but unjustified assumption: that any link between obesity and advertising occurs because more advertising causes higher rates of obesity. But the study at hand showed only an association: people living in areas with more food ads were more likely to be obese than people living in areas with fewer food ads. To be fair, the researchers correctly note that additional steps would be needed to prove that food ads cause obesity. But until those steps are taken, talk of restricting ads is premature. In fact, it is easy to imagine how the causation could run the opposite way (something the article did not mention): If food vendors believe obese people are more likely than non-obese people to buy their products, they will place more ads in areas where obese people already live. Suppose we counted ads for fitness-oriented products like bicycles and bottled water, and found more of those ads in places with less obesity. Would it then be wise anti-obesity policy to subsidize such ads? Or would the smarter conclusion be that the fitness companies suspect that the obese are less likely than the fit to buy their products?

When we seek to base policy on evidence, we must remember that not all “evidence” is created equal. Taken at face value, the study on ads and obesity provides some indication that the two are linked, but no evidence that food ads cause obesity. The fact that the causal conclusion may coincide with a moral belief — that it is wrong to tempt people who overeat by showing them ads for food — does not make it valid.

Over and over, Daniel Yuan, a medical doctor and statistician, couldn’t understand the results coming out of the lab, a prestigious facility at Johns Hopkins Medical School funded by millions from the National Institutes of Health.He raised questions with the lab’s director. He reran the calculations on his own. He looked askance at the articles arising from the research, which were published in distinguished journals. He told his colleagues: This doesn’t make sense.“At first, it was like, ‘Okay — but I don’t really see it,’ ” Yuan recalled. “Then it started to smell bad.”

The passions of scientific debate are probably not much different from those that drive achievement in other fields, so a tragic, even deadly dispute might not be surprising.But science, creeping ahead experiment by experiment, paper by paper, depends also on institutions investigating errors and correcting them if need be, especially if they are made in its most respected journals.If the apparent suicide and Yuan’s detailed complaints provoked second thoughts about the Nature paper, though, there were scant signs of it.The journal initially showed interest in publishing Yuan’s criticism and told him that a correction was “probably” going to be written, according to e-mail rec­ords. That was almost six months ago. The paper has not been corrected.The university had already fired Yuan in December 2011, after 10 years at the lab. He had been raising questions about the research for years. He was escorted from his desk by two security guards.

Fang said retractions may be rising because it is simply easier to cheat in an era of digital images, which can be easily manipulated. But he said the increase is caused at least in part by the growing competition for publication and for NIH grant money.He noted that in the 1960s, about two out of three NIH grant requests were funded; today, the success rate for applicants for research funding is about one in five. At the same time, getting work published in the most esteemed journals, such as Nature, has become a “fetish” for some scientists, Fang said.

academic researchers and scientists at companies like Microsoft, I.B.M. and Hewlett-Packard have been working to develop quantum computers.

Lockheed Martin — which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago — is confident enough in the technology to upgrade it to commercial scale, becoming the first company to use quantum computing as part of its business.

if it performs as Lockheed and D-Wave expect, the design could be used to supercharge even the most powerful systems, solving some science and business problems millions of times faster

On what seems like a monthly basis, scientific teams announce the results of new experiments, adding to a preponderance of evidence that we’ve been underestimating animal minds, even those of us who have rated them fairly highly

an international group of prominent neuroscientists meeting at the University of Cambridge issued “The Cambridge Declaration on Consciousness in Non-Human Animals,” a document stating that “humans are not unique in possessing the neurological substrates that generate consciousness.” It goes further to conclude that numerous documented animal behaviors must be considered “consistent with experienced feeling states.”

Only with the Greeks does there enter the notion of a formal divide between our species, our animal, and every other on earth.

The law, approved last March by Israel's legislating Knesset, requires models to prove they have maintained a Body Mass Index (BMI) of at least 18.5 for three months prior to a fashion shoot or show.

"This law is another step in the war against eating disorders,"

But critics of the law in this country say it and others like it—the Madrid Fashion Show's ban on women whose BMI is below 18, for example, and Milan's Fashion Week's ban on models with a BMI below 18.5—are misguided, focusing on weight instead of health.

Ethnocentrism – our culture’s tendency to twist our judgment in favor of homegrown beliefs and practices and against foreign alternatives – is not, I take it, a phenomenon in need of further empirical confirmation

in his recent book, “The Righteous Mind: Why Good People Are Divided by Politics and Religion,” Jonathan Haidt argues that, far from being a way of holding our moral beliefs up to critical scrutiny, moral reasoning is generally something we use merely to convince others of long-held beliefs that we are unwilling to abandon.

often, no amount of persuasive reasoning, clear argument or exposed contradiction can shake us from what we already believe.

the age of Skinnerian Marketing. Future applications making use of big data, location, maps, tracking of a browser's interests, and data streams coming from mobile and wearable devices, promise to usher in the era of unprecedented power in the hands of marketers, who are no longer merely appealing to our innate desires, but programming our behaviors.

In the 1930's, B. F. Skinner developed the concept of operant conditioning. He put pigeons and rats in Skinner boxes to study how he could modify their behavior using rewards and punishments.

Skinner's techniques of operant conditioning and his notorious theory of behavior modification were denounced by his critics 70 years ago as fascist, manipulative vehicles that could be used for government control.

A panoply of devices and ideas are named after Archimedes. Besides the Archimedes screw, there is the Archimedes principle, the law of buoyancy that states the upward force on a submerged object equals the weight of the liquid displaced. There is the Archimedes claw, a weapon that most likely did exist, grabbing onto Roman ships and tipping them over. And there is the Archimedes sphere, a forerunner of the planetarium — a hand-held globe that showed the constellations as well as the locations of the sun and the planets in the sky.

Dr. Rorres said the singular genius of Archimedes was that he not only was able to solve abstract mathematics problems, but also used mathematics to solve physics problems, and he then engineered devices to take advantage of the physics. “He came up with fundamental laws of nature, proved them mathematically and then was able to apply them,” Dr. Rorres said.

Haidt’s view here is not at all alien to Plato, who saw truth arising only from the right sort of discussion among inquirers accountable to one another. Nor would Plato object to Haidt’s claim that ethics is based on intuition — direct moral judgments — rather than on reasoning. Haidt’s “reasoning” corresponds to what Plato calls dianoia, the process of logically deriving conclusions from given premises.

Such logic yields merely hypothetical knowledge (if p, then q), since logic cannot prove the truth of its premises.  Reasoning, therefore, will reliably yield truth only when it is completed by acts of intuition (noesis) that justify the premises from which we reason.

Plato’s intuitions are not like the snap judgments of everyday life, driven by genes and social conditioning. But nor are they the insights of individuals meditating in isolation.

A myth is a narrative that people tell to express their most basic views about what the world is like and how they should live in it. The myth serves that purpose whether it’s totally false, totally true, or (as is usually the case) some mixture of the two.

Fact-checking the myth is irrelevant to its role in the lives of the people who tell it.  They do not judge it by whether it can be proven factually true. Rather, it shapes their view of truth; it tells them what they can accept as factually true and what they must consider false. So they act out their myth in a ritual to reinforce their commitment to truth as the myth teaches them to see it -- or so the old theory goes.

What happens when fact-checking itself becomes a ritual? I don’t have quantitative data, but it seems to me that we have much more fact-checking in this presidential election than in any election before

Despite the high regard in which Americans have held the military for generations, there is a lot about the military that those who haven’t served don’t quite understand.

That gap of understanding between the protected and their protectors is typically bridged by mutual respect, but can also be a gutter in which liars and character assassins slither.

As any veteran will tell you, a DD-214 is THE definitive record of a person’s time in the military, used to prove the authenticity, duration and character of said service.  The official name for the form is Certificate of Release or Discharge from Active Duty and veterans learn early on to keep a copy handy.

A well-known theory holds that most people, at least in the US and perhaps in the world, are six degrees of separation away from each other. Pick a random stranger anywhere in the country, the theory goes, and chances are you can build a chain of acquaintances between the two of you in no more than six hops.

The idea of "six degrees of separation" rests on a scientific foundation that's dubious at best. But Facebook, because its users give it access to possibly the richest data set ever on how 1.6 billion people know and interact with each other, set out to prove it with a statistical algorithm.

The average Facebook user is three and a half degrees of separation away from every other user, and the social network's post tells you your own distance from everyone else on the site.

According to the Innocence Project, one in four people who have been exonerated for crimes they didn't commit confessed to that crime.

Psychologists have documented several reasons this might occur. The big one is that interrogating police officers can impose their suggestions on suspects: "We have evidence proving you were there!" "Your fingerprints were found!"

Only about 18 percent of the well-rested participants signed the form (such is the baseline power of an authority figure demanding guilt). But the results were more dramatic in the sleep-deprived condition. "That 18 percent now has risen to 50 percent," Loftus says.

“I will buy one only if it has the potential to be the best. I’m not interested in having a nine.”

A friend asked me later whether Trump wasn’t “in on the joke” of his public persona, and I said that, as far as I could tell, the Trump we were used to seeing on television was the honest-to-god authentic Trump: a ten-year-old boy who, for unknown reasons, had been given a real airplane and a billion dollars. In other words, a fun guy to hang around with.

He was upset that I hadn’t written that he’d shot 71—a very good golf score, one stroke under par.

The Mistrust of Science

The scientific orientation has proved immensely powerful. It has allowed us to nearly double our lifespan during the past century, to increase our global abundance, and to deepen our understanding of the nature of the universe. Yet scientific knowledge is not necessarily trusted. Partly, that’s because it is incomplete. But even where the knowledge provided by science is overwhelming, people often resist it—sometimes outright deny it. Many people continue to believe, for instance, despite massive evidence to the contrary, that childhood vaccines cause autism (they do not); that people are safer owning a gun (they are not); that genetically modified crops are harmful (on balance, they have been beneficial); that climate change is not happening (it is).

People are prone to resist scientific claims when they clash with intuitive beliefs. They don’t see measles or mumps around anymore. They do see children with autism. And they see a mom who says, “My child was perfectly fine until he got a vaccine and became autistic.”

The wealthy, says Smith, spend their days establishing an “economy of greatness,” one founded on “luxury and caprice” and fueled by “the gratification of their own vain and insatiable desires.” Any broader benefit that accrues from their striving is not the consequence of foresight or benevolence, but “in spite of their natural selfishness and rapacity.” They don’t do good, they are led to it.

In other words, the invisible hand did not solve the problem of politics by making politics altogether unnecessary. “We don’t think government can solve all our problems,” President Obama said in his convention address, “But we don’t think that government is the source of all our problems.” Smith would have appreciated this formulation. For him, whether government should get out of the way in any given matter, economic or otherwise, was a question for considered judgment abetted by scientific inquiry.

What it did not do, however, was void any proposal outright, much less prove that all government activity was counterproductive. Smith held that the sovereign had a role supporting education, building infrastructure and public institutions, and providing security from foreign and domestic threats — initiatives that should be paid for, in part, by a progressive tax code and duties on luxury goods. He even believed the government had a “duty” to protect citizens from “oppression,” the inevitable tendency of the strong to take advantage of the ignorance and necessity of the weak.

For the first time, biologists have succeeded in growing human stem cells in pig embryos, shifting from science fiction to the realm of the possible the idea of developing human organs in animals for later transplant.

Since the organ would be made of a patient’s own cells, there would be little risk of immune rejection.

They would be generated by implanting human stem cells into an early pig embryo, resulting in an animal composed of mixed pig and human cells.

TV is drowning in cheap, sloppily executed deaths

The spring of 2016 has been marked by death after death after death on TV. Some have proved controversial. Some have passed without commentary. A couple have been largely applauded.

But the fact remains: TV is killing major characters at an astonishing rate.
