Brain Thing Correlates With Other Brain Thing is the expected result of any two Brain Things, because all the Brain Things correlate. The failure here is a variant of the Streetlight Effect; we looked for this one correlation, we found it, so it must be important. It's not, unless it's really strong, because in this space, everything correlates to everything. To be important, there needs to be something more than "a correlation"; that's so expected as to be a near zero-bit contribution to science. For there not to be any correlation would actually be the surprising thing!
- syzarian 4y agoFrom my brief reading on dyadic regression your first sentence is why dyadic regressions are used in the circumstances of the paper. I don’t know the validity of the paper but I do strongly suspect Sabine doesn’t either and that her Tweet says more about her ignorance of the topic than it does about the validity of the paper.

See also the attempt to filter out "confounding" variables in more normal statistical analyses; I personally believe that the effectiveness of such tools are extremely overstated and overestimated. There is a certain intrinsic circularity to any such tool.
