Any sociological question is likely going to have a complex answer with many variables that are not easy to tease apart. We should therefore resist the temptation to make simplistic statements about X being the cause of Y. We can still, however, identify correlations that will at least inform our thinking. Sometimes correlations can be triangulated to fairly reliable conclusions.
When the data is complex and difficult to interpret, however, evidence tends to be overwhelmed by narrative. The recent Sandy Hook tragedy is an excellent example. No one knows exactly why the shooter did what he did, so it is easy to insert your own preferred narrative as the explanation.
Another example is the phenomenon of so-called complementary and alternative medicine (CAM). Why has it been increasing in popularity (and is it, really?). Is it slick marketing, relaxed regulations, scientific illiteracy, a gullible media, or the failures of mainstream medicine? You can probably guess I think it’s all of these things to some degree. The most common narrative I hear by far, however, is the latter – if people are turning to CAM it must be because mainstream medicine has failed them. This version of reality is often promoted by CAM marketing.
The evidence that we have, however, simply does not support this narrative. Studies show that satisfaction with mainstream medicine is not an important factor in deciding to use CAM, that CAM users are generally satisfied with their mainstream care, and they use CAM because it aligns with their philosophy, and they simply want to expand their options.
None of this is to imply that mainstream medicine has no problems or failings – it does. We should, however, be working toward keeping and improving what works and fixing what doesn’t, not discarding science and reason to embrace fantasy as an alternative. This is often the false choice presented by CAM proponents, and is analogous to creationists pointing out alleged weaknesses in the theory of evolution as an argument for creationism as an alternative.
