OKCupid dataset (not public right now, contact me if you want the password). Draft paper: https:\/\/osf.io\/p9ixw\/<\/p>\n

I looked at whether there was evidence for cognitive dysgenics in the OKCupid dataset. The unrepresentativeness of the dataset is not much of a problem here: indeed we are very much interested in younger people looking to date since these are the parents of the next generation and some are already parents of course.<\/p>\n

The cognitive test is made of an ad hoc collection of 14 items. It seems to work fairly well. The items were scored using item response theory.<\/p>\n

There are a couple of questions related to fertility, either desired or actual. The relationships to cognitive ability looks like this:<\/p>\n

\"q105\"<\/a> \"q979\"<\/a> \"q80041\"<\/a><\/p>\n

These are the raw relationships. One may wonder if they are confounded with, e.g. race or age. So one could try a multiple regression. Unfortunately, since the outcomes are ordinal data, standard multiple regression results in a large downward bias<\/a>. Still, results look like this:<\/p>\n

The dependent variable was the question above about the number of desired children. Still, we see a small negative coefficient as expected. The size is similar to other studies. Since the cognitive measure was not optimal, it is probably somewhat larger.<\/p>\n
