It's an analysis of cognitive decline from "active coping and grit". The study is being done exclusively on a black cohort, it appears from their Background, because these studies have already been done on white cohorts and they have the data available already to do the comparisons. I'm not a scientist, feel free to correct me, someone, if I'm misreading this.
Is the use of the data appropriate/applicable to what the linked article is suggesting? Probably not.
- gwern 1y agoI did skim it, but it didn't help me much, because I didn't see any comparison to the supposed other cohorts, and even if they had done those, an online convenience sample is almost certainly going to differ a lot in many ways from whatever other white cohort you used from a different study, whereas you could've simply recruited white participants from the same service and gotten an obviously much more valid comparison group.
