The last decade has witnessed unprecedented investment by researchers and funding agencies in the pursuit of G × E across many dimensions of human variation. Many of the models employed have been far simpler than some of those considered here and, once statistical significance has been achieved, publishable rationalization lurks close behind. Unfortunately, errors of the type described in this note are among the easiest to replicate and their uncritical dissemination risks distracting researchers from the more time-consuming task of “trying to get it right.”
