Baumeister and his colleagues didn’t come down particularly hard on the psychologists and others who had contributed to the self-esteem craze. “Was it reasonable to start boosting self-esteem before all the data were in?” they wrote in one of the papers. “Perhaps. We recognize that many practitioners and applied psychologists must deal with problems before all the relevant research can be conducted.” This is, in fact, a common occurrence in social science: You have a handful of papers pointing to a correlation that could have important real-world ramifications, assuming certain things are true. But it takes a while to determine whether those certain other things are true, and in the meantime other people — people who might not be as committed to scientific rigor as the best social scientists are, or who are trying to solve urgent real-world problems and don’t have the luxury of waiting for more peer-reviewed evidence to come in — might decide to run with the idea before the evidence is in.

That seems to be what happened here. Despite the absence of causal evidence linking self-esteem to positive outcomes, it was such an irresistible story that, from the point of view of excitable politicians like Vasconcellos, there was enough evidence to go ahead and run with it. And thus a simple, highly viral message — raising self-esteem can greatly improve people’s lives and productivity — was able to catch on because it offered a straightforward solution to a constellation of problems that are not, in fact, straightforward to solve. It felt like an easy fix because none of the nuance that should go into rigorous social science filtered down to policy makers themselves — many of those policy makers developed misconceptions about what, exactly, bona fide experts had and hadn’t discovered. “Social researchers have long told us that a lack of self-esteem underlies society’s most pressing problems,” wrote a Maryland House delegate in a 1989 letter to the editor which ran in the Washington Post, “the ones government shells out big dollars to alleviate.” She was wrong, of course, but it’s not hard to understand where she might have gotten the idea. The fact that self-esteem was such a bipartisan hit, with liberals and conservatives both supporting it in fairly high numbers (albeit couched in slightly different reasoning), also made it tougher for any unified opposition to the concept to develop — though there were certainly some (again, mostly ignored) skeptics along the way, among them conservative social commentators like Charles Krauthammer and “Dr. Laura” Schlessinger who saw the self-esteem movement as yet another manifestation of the saccharine mushy self-help drivel that was, in their view, undermining America.

This right here seems to be the core problem. And the problem seems to be getting worse, leaking beyond the realms of the social sciences.

The public seems to be relying more and more on science for guidance as our media and politicians keep failing us. But most people don't really understand what science is! You can defend anything with "science" if all you're looking for is some study that claims to show evidence for whatever it is you're defending.

I'm not sure what the answer is. A massive education campaign to inform the public about how to interpret studies and draw conclusions that are actually supported by science? Higher standards for scientific publications regarding content and reproducibility? Regulations which would force media to disclose more information about the "studies" they cite?
