Overscreening is recognized as a problem among epidemiologists.
Rationality does not specify values. I rather suspect that the cost-benefit analysis that epidemiologists look at is quite different from the cost-benefit analysis that individuals look at.
these screenings are either a problem in themselves, or that the information from the screenings can lead people to irrational behavior
LOL. Don't bother you pretty little head with too much information. No, you don't need to know that. No, you can't decide what you need to know and what you don't need to know. X-/
Jason Mitchell is [edit: has been] the John L. Loeb Associate Professor of the Social Sciences at Harvard. He has won the National Academy of Science's Troland Award as well as the Association for Psychological Science's Janet Taylor Spence Award for Transformative Early Career Contribution.
Here, he argues against the principle of replicability of experiments in science. Apparently, it's disrespectful, and presumptively wrong.
This is why we can't have social science. Not because the subject is not amenable to the scientific method -- it obviously is. People are conducting controlled experiments and other people are attempting to replicate the results. So far, so good. Rather, the problem is that at least one celebrated authority in the field hates that, and would prefer much, much more deference to authority.
