Am I the only one that questions the validity of self reported survey data? No, the concerns are extremely well documented, including documentation about psychological and situational factors that impact the results.
- mikem170 2y agoSo it's possible that the numbers have changed even more than this study shows?
- hx8 2y agoSure, I'm not arguing in which direction the numbers reflect Truth. I'm simply saying I trust teenage self reported cannabis usage about as much as I trust self reported exercise habits. I'm very skeptical, and I don't think we can assume constant variance in self reporting across different time and institutions.
- mikem170 2y agoDoes that mean all self reported studies are worthless, in your opinion?
