I agree with everything you said. Especially with medicine, it is very difficult to communicate new findings with the public. I did have some conversations with people how to communicate science with a society that includes graduated bachelor students who cannot tell a mol from a mole.
I think that the mind still is a purely biological thing (I am not spiritual). On a more abstract level you could compare the mind with our gut. Food (input) triggers local effect which can become systemic. I am glad that psychology and sociology are being incorporated into medicine because it really is a factor. I see one big problem with that though: who will take care of it? I know that in the US there is a medical school admissions test (MCAT) which now features a big psychology section asking useless details (what stage is this kid in if it does that?). I think it would be wrong to ask doctors to be psychologists (which seems to become a thing in the US). Rather, psychologists should be employed in hospitals and team work should be encouraged. Another thing is that people now tend to be less social. My grandparents and even parents were very involved in clubs and societies, things that are not as popular anymore (unless you are a student). Anyways, sorry for the VERY long reply. Thanks for stopping by and the quality comment! Cheers!
