In academic research, “sudden wealth syndrome” describes the feeling right after you’ve received a big grant, and you suddenly realize you have a lot of work to do. As a blogger, I can also relate to #7 above.
. . . and statisticians
It’s easy to make fun of psychiatrists for this sort of thing–but if statisticians had a similar official manual (not a ridiculous scenario, given that the S in DSM stands for Statistical), it would be equally ridiculous, I’m sure.
Sometimes this comes up when I hear about what is covered in graduate education in statistics and biostatistics–a view of data analysis in which each different data structure gets its own obscurely named “test” (Wilcoxon, McNemar, etc.). The implication, I fear, is that the practicing statistician is like a psychiatrist, listening to the client, diagnosing his or her problems, and then prescribing the appropriate pill (or, perhaps, endless Gibbs sampling^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H talk therapy). I don’t know if I have a better model for the training of thousands of statisticians, nor maybe do I have a full understanding of what statistical practice is like for people on the inferential assembly line, as it were. But I strongly feel that the testing approach–and, more generally, the approach of picking your method based on the data structure–is bad statistics. So I’m pretty sure I’d find much to mock in any DSM-of-statistics that might be created.
Another uncomfortable analogy between the two professions is that statistical tests, like psychiatric diagnoses, are trendy, despite their supposed firm foundation in mathematics and demonstrated practical success (just as psychiatry boasts a firm foundation medicine along with millions of satisfied customers over the decades). Compounding the discomfort is that some of the oldest and most established statistical tests are often useless or even counterproductive. (Consider the chi-squared test, which when used well can be helpful–see chapter 2 of ARM for an example–but is also notorious as being nothing more than “a test of sample size” and has let many researchers to disastrously oversimplify their data structures in order to fit the crudest version of this analysis.)
Instead of a DSM, the statistical profession has various standard textbooks, from Snedecor and Cochran to . . . whatever. But our informal DSM, as defined by practice, word-of-mouth, and our graduate curricula, is nothing to be proud of.
