Regarding adding IQ tests to biobank data: I doubt this will happen soon. Steve Hsu recently indicated in a podcast with Alex Murshak that he thinks it will still take many years before biobanks will have a sufficient mass of IQ tests to go along with their data. Of course, this isn’t due to a technical hurdle. (The Wonderlic, for instance, is an easy test you could administer to biobank participants at low cost.) Rather, it’s due to the fact that this research is in general verboten in the West; in China, the failure to gather IQ test data along with other data is due more to inadvertence than anything else.
That said, I do think there are some clever ways you could probably get information that is nearly as good as IQ tests. For example, working memory test batteries (consisting of complex span tasks) and processing speed test batteries seem to approximate fluid intelligence really well. Gathering this data could probably be more easily justified because it’d probably help with other kinds of neurological research (e.g., dementia research maybe?).
