Also, largely, there is no scientific evidence for the vast majority of problems.

The only evidential basis for causal analysis are experiments where (1) you intervene to bring about the cause deterministically; and (2) where you control all confounding causes.

Those conditions are impossible to meet for the vast majority of interactions in complex systems, such as people & medicine.

If you run associative statistics on counfounded data collected in observational studies, you may as well correlate star signs with outcomes -- no doubt people being treated under winter signs will do worse than those under gemini. Astrology QED.

Brings to mind an interesting tidbit I ran into--long ago your sign probably did correlate with meaningful things in life. Not that the stars mattered, but the seasons did. Early life nutrition would vary. Even today you'll find a correlation between signs and ADHD diagnoses--because of the school year. There is almost a year of difference between the oldest students entering school and the youngest--and those youngest are appreciably more likely to get an ADHD diagnosis.
