You can even perform the experiment yourself.
For people with certain conditions, like ADHD, the obvious best thing for 'brain fog' is not lifting weights. I'm sure it helps, but that's not top of the list.
Also, lifting weights is just one type of exercise. A lot of studies are actually focused on exercise as a whole, and some only aerobic exercise. I'm sure lifting weights is great, but is it better than, say, running? I'm not convinced.
You made the claim. Supporting it is your burden. And a few searches found no comparisons of weight training to other high intensity exercise. Or meditation. Or puzzles. Or nootropics.

Is this a funding offer? Or ignorance of experiment design?
It will make your dick harder (or clitoris, whatever), your muscles bigger, your mind clearer, your sense of purpose more apparent. It will increase your bone density, and improve your sense of well being. Things that aren’t doing you any favours will tend to fall by the wayside.
Failing that, asking people who’ve tried the resistance training / puzzles / nootropics / meditation experiment themselves is a low effort way of revealing a pattern.
Imagine it’s 2025, there’s an obesity epidemic, and people still think they can sit around and do fuck all to get well.
