      Also, not controlling for a covariate on which groups of interest differ makes a statistical analyses stronger? 🤔

      It does because the direction of the confounder is opposite of claimed effect. And yes, IQ ~~ brain size for ~every area.

      Update: IQ table was labeled the wrong way (in which case authors should have still controlled for this as covariate that may drive group d)pic.twitter.com/RZSWxQ1HFQ

      Well, since ADHDers do have lower IQ (about 9 points), this seems fine. http://psycnet.apa.org/journals/neu/18/3/543/ …

      If you control for these things, you change the question from: brain size differences bwtn ADHDers and normies to

      brain size diffs between ADHDers and normies GIVEN equal IQs. I.e. you subsample to the smarter ADHDers.

      Kinda sorta. Depends what your precise question is. Depends on your causal model whether you want to control or not! If you think lower IQ

      is a confounder, i.e. both have same cause, then you prob want to control; but if you think lower IQ is effect of ADHD, then controlling is

      controlling for some of the indirect effects of ADHD. So, depends on your causal thinking. Both questions are relevant IMO.
