New research on self-control explains the link between religion and health
Ever since 2000, when psychologist Michael E. McCullough, now at the University of Miami, and his colleagues published a metaanalysis of more than three dozen studies showing a strong correlation between religiosity and lower mortality, skeptics have been challenged by believers to explain why—as if to say, “See, there is a God, and this is the payoff for believing.”
In science, however, “God did it” is not a testable hypothesis. Inquiring minds would want to know how God did it and what forces or mechanisms were employed (and “God works in mysterious ways” will not pass peer review). Even such explanations as “belief in God” or “religiosity” must be broken down into their component parts to find possible causal mechanisms for the links between belief and behavior that lead to health, well-being and longevity. This McCullough and his then Miami colleague Brian Willoughby did in a 2009 paper that reported the results of a metaanalysis of hundreds of studies revealing that religious people are more likely to engage in healthy behaviors, such as visiting dentists and wearing seat belts, and are less likely to smoke, drink, take recreational drugs and engage in risky sex. Why? Religion provides a tight social network that reinforces positive behaviors and punishes negative habits and leads to greater self-regulation for goal achievement and self-control over negative temptations.

It’s not what you think
IN THE 1990S I had the opportunity to dine with the late musician Isaac Hayes, whose career fortunes had just made a stunning turnabout upward, which he attributed to Scientology. It was a glowing testimonial by a sincere follower of the Church, but is it evidence that Scientology works? Two recently published books argue that there is no science in Scientology, only quasireligious doctrines wrapped in New Age flapdoodle masquerading as science. The Church of Scientology, by Hugh B. Urban, professor of religious studies at Ohio State University, is the most scholarly treatment of the organization to date, and investigative journalist Janet Reitman’s Inside Scientology is an electrifying read that includes eye-popping and well-documented tales of billion-year con tracts, aggressive recruitment programs, and verbal and physical abuse of staffers.
The problem with testimonials is that they do not constitute evidence in science. As social psychologist Carol Tavris told me, “Every therapy produces enthusiastic testimonials because of the justification-of-effort effect. Anyone who invests time and money and effort in a therapy will say it helped. Scientology might have helped Isaac Hayes, just as psychoanalysis and bungee jumping might have helped others, but that doesn’t mean the intervention was the reason. To know if there is anything special about Scientology, you need to do controlled studies—randomly assigning people to Scientology or a control group (or a different therapy) for the same problem.” To my knowledge, no such study has been conducted. The real science behind Scientology seems to be an understanding of the very human need, as social animals, to be part of a supportive group—and the willingness of people to pay handsomely for it.

Be skeptical of claims that we live in an ever more dangerous world
ON JULY 22, 2011, a 32-year old Norwegian named Anders Behring Breivik opened fire on participants in a Labour Party youth camp on the island of Utoya after exploding a bomb in Oslo, resulting in 77 dead, the worst tragedy in Norway since World War II.
English philosopher Thomas Hobbes famously argued in his 1651 book, Leviathan, that such acts of violence would be commonplace without a strong state to enforce the rule of law. But aren’t they? What about 9/11 and 7/7, Auschwitz and Rwanda, Columbine and Fort Hood? What about all the murders, rapes and child molestation cases we hear about so often? Can anyone seriously argue that violence is in decline? They can, and they do—and they have data, compellingly compiled in a massive 832-page tome by Harvard University social scientist Steven Pinker entitled The Better Angels of Our Nature: Why Violence Has Declined (Viking, 2011). The problem with anecdotes about single events is that they obscure long-term trends. Breivik and his ilk make front-page news for the very reason that they are now unusual. It was not always so.

Distinguishing between science and pseudoscience
is problematic
CLIMATE DENIERS ARE ACCUSED OF PRACTICING PSEUDOSCIENCE, as are intelligent design creationists, astrologers, UFOlogists, parapsychologists, practitioners of alternative medicine, and often anyone who strays far from the scientific mainstream. The boundary problem between science and pseudoscience, in fact, is notoriously fraught with definitional disagreements because the categories are too broad and fuzzy on the edges, and the term “pseudoscience” is subject to adjectival abuse against any claim one happens to dislike for any reason. In his 2010 book Nonsense on Stilts (University of Chicago Press), philosopher of science Massimo Pigliucci concedes that there is “no litmus test,” because “the boundaries separating science, nonscience, and pseudoscience are much fuzzier and more permeable than Popper (or, for that matter, most scientists) would have us believe.”
It was Karl Popper who first identified what he called “the demarcation problem” of finding a criterion to distinguish between empirical science, such as the successful 1919 test of Einstein’s general theory of relativity, and pseudoscience, such as Freud’s theories, whose adherents sought only confirming evidence while ignoring disconfirming cases. Einstein’s theory might have been falsified had solar-eclipse data not shown the requisite deflection of starlight bent by the sun’s gravitational field. Freud’s theories, however, could never be disproved, because there was no testable hypothesis open to refutability. Thus, Popper famously declared “falsifiability” as the ultimate criterion of demarcation. (continue reading…)

Why the world is not flat…yet
FAST-FORWARD TO THE YEAR 2100. Computers, writes physicist and futurist Michio Kaku in Physics of the Future (Doubleday, 2011), will have humanlike intelligence, the Internet will be accessible via contact lenses, nanobots will eliminate cancers, space tourism will be cheap and popular, and we’ll be colonizing Mars. We will be a planetary civilization capable of consuming the 1017 watts of solar energy falling on Earth to meet our energy needs, with the Internet as a worldwide telephone system; English and Chinese as the contenders for a planetary language; a unified culture of common foods, fashions and films; and a truly global economy with many more international trading blocs such as we see today in the European Union and NAFTA.
Kaku’s vision of how the exchange of science, technology and ideas among all peoples will create a global civilization with greatly weakened nation-states and almost no war is epic in its scope and heroic in its inspiration. Many have felt similar hope for a united, peaceful future through globalization. Indeed, I evoked a similar image in my book The Mind of the Market (Holt, 2009), and I was inspired in part by Thomas Friedman’s wildly popular The World Is Flat (Farrar, Straus and Giroux, 2005), in which he argues for “a global, Web-enabled playing field that allows for multiple forms of collaboration on research and work in real time, without regard to geography, distance or, in the near future, even language.” (continue reading…)
