In my experience, with enough data you do find lots of correlations between psychiatric symptoms and "cogneuro" measures, but always r ~ 0.15-.20. maybe .3 for very general measures like RT. This leads me to believe the vast majority of small-n symptom correlations are dubious.
Why do think it’s uncommon to trust subjects self-reported symptoms? Wouldn’t wouldn’t self reported symptoms be some of the best data for understanding perception and mh overall?
