Ehhhh I feel like the researchers took 5000 variables and threw them at the wall to see what sticks.

Living near busy roads is usually cheaper... And I doubt people with dementia are locking down C level positions

The study specifically adjusts for poverty/lifestyle.

[reddytowns]

But what proof is there that their adjustments covered every possible cause? I would suggest this is by definition impossible, since if we knew every possible cause for dementia, we would not need to do the study.

[dpark]

They obviously didn't cover every possible cause nor should they be expected to. With that logic no one could ever do an empirical study.

[reddytowns]

True, but there should be some rationale as to why they assume that normalization wrt the cofactors they've chosen are sufficient to provide for their conclusions.

Simply seemingly randomly choosing cofactors and then shrugging it off as good enough to draw conclusions from is sloppy. Typical, yes, but mean you shouldn't be skeptical of their conclusions, no.

[dpark]

Your specific concern was about socioeconomic status and because they answered that you now call it a random cofactor. Come on. You're not giving meaningful criticism. You're just being negative.
