"It’s been just over twenty-five years since Prozac came to market, and more than twenty per cent of Americans now regularly take mind-altering drugs prescribed by their doctors. Almost as familiar as brands like Zoloft and Lexapro is the worry about what it means that the daily routine in many households, for parents and children alike, includes a dose of medications that are poorly understood and whose long-term effects on the body are unknown. Despite our ambivalence, sales of psychiatric drugs amounted to more than seventy billion dollars in 2010. They have become yet another commodity that consumers have learned to live with or even enjoy, like S.U.V.s or Cheetos.
Yet the psychiatric-drug industry is in trouble. “We are facing a crisis,” the Cornell psychiatrist and New York Times contributor Richard Friedman warned last week. In the past few years, one pharmaceutical giant after another—GlaxoSmithKline, AstraZeneca, Novartis, Pfizer, Merck, Sanofi—has shrunk or shuttered its neuroscience research facilities. Clinical trials have been halted, lines of research abandoned, and the new drug pipeline has been allowed to run dry.
Why would an industry beat a hasty retreat from a market that continues to boom? (Recent surveys indicate that mental illness is the leading cause of impairment and disability worldwide.) The answer lies in the history of psychopharmacology, which is more deeply indebted to serendipity than most branches of medicine—in particular, to a remarkable series of accidental discoveries made in the fifteen or so years following the end of the Second World War.

"Whether or not truthiness, as one might call it, is good medicine remains to be seen. No one knows how important placebo effects are to successful treatment, or how exactly to implement them, a topic Michael Specter wrote about in the magazine in 2011. But the dry pipeline of new drugs bemoaned by Friedman is an indication that the drug industry has begun to lose faith in the myth it did so much to create. As Steven Hyman, the former head of the National Institute of Mental Health, wrote last year, the notion that “disease mechanisms could … be inferred from drug action” has succeeded mostly in “capturing the imagination of researchers” and has become “something of a scientific curse.” Bedazzled by the prospect of unraveling the mysteries of psychic suffering, researchers have spent recent decades on a fool’s errand—chasing down chemical imbalances that don’t exist. And the result, as Friedman put it, is that “it is hard to think of a single truly novel psychotropic drug that has emerged in the last thirty years.”
Despite the BRAIN initiative recently announced by the Obama Administration, and the N.I.M.H.’s renewed efforts to stimulate research on the neurocircuitry of mental disorder, there is nothing on the horizon with which to replace the old story. Without a new explanatory framework, drug-company scientists don’t even know where to begin, so it makes no sense for the industry to stay in the psychiatric-drug business. And if loyalists like Hyman and Friedman continue to say out loud what they have been saying to each other for many years—that, as Friedman told Times readers, “just because an S.S.R.I. antidepressant increases serotonin in the brain and improves mood, that does not mean that serotonin deficiency is the cause of the disease”—then consumers might also lose faith in the myth of the chemical imbalance.
