The Widening World of Hand-Picked Truths

NY Times

Nearly half a century ago, in what passed as outrage in pre-Internet times, people across the country became incensed by the latest edition of Time magazine. In place of the familiar portrait of a world leader — Indira Gandhi, Lyndon B. Johnson, Ho Chi Minh — the cover of the April 8, 1966, issue was emblazoned with three red words against a stark black background: “Is God Dead?”

Thousands of people sent letters of protest to Time and to their local newspapers. Ministers denounced the magazine in their sermons.

The subject of the fury — a sprawling, 6,000-word essay of the kind Time was known for — was not, as many assumed, a denunciation of religion. Drawing on a panoply of philosophers and theologians, Time’s religion editor calmly considered how society was adapting to the diminishing role of religion in an age of secularization, urbanism and, especially, stunning advances in science.

With astronauts walking in space, and polio and other infectious diseases seemingly on the way to oblivion, it was natural to assume that people would increasingly stop believing things just because they had always believed them. Faith would steadily give way to the scientific method as humanity converged on an ever better understanding of what was real.

Almost 50 years later, that dream seems to be coming apart. Some of the opposition is on familiar grounds: The creationist battle against evolution remains fierce, and more sophisticated than ever. But it’s not just organized religions that are insisting on their own alternate truths. On one front after another, the hard-won consensus of science is also expected to accommodate personal beliefs, religious or otherwise, about the safety of vaccines, G.M.O. crops, fluoridation or cellphone radio waves, along with the validity of global climate change.

Like creationists with their “intelligent design,” the followers of these causes come armed with their own personal science, assembled through Internet searches that inevitably turn up the contortions of special interest groups. In an attempt to dilute the wisdom of the crowd, Google recently tweaked its algorithm so that searching for “vaccination” or “fluoridation,” for example, brings vetted medical information to the top of the results.

But presenting people with the best available science doesn’t seem to change many minds. In a kind of psychological immune response, they reject ideas they consider harmful. A study published this month in the Proceedings of the National Academy of Sciences suggested that it is more effective to appeal to anti-vaxxers through their emotions, with stories and pictures of children sick with measles, the mumps or rubella — a reminder that subjective feelings are still trusted over scientific expertise.[...]
