thread on Dunbar's "anatomy of friendship" paper, expanding on the famous "Dunbar number". h/t @__drewface for the rec 150 is the number of people with whom you can have a "mutual, reciprocal relationship of trust and obligation, combined with a willingness to act prosocially".

my beef with mental health culture is that it adopts the medical frame, so saying you have a mental health issue is equivalent to saying "I have a problem and I'm outsourcing the solution to the professional class of therapists and psychiatrists". (1/N) I guess I just don't accept the legitimacy of that professional class in helping solve people's life problems! Unlike surgeons and antibiotic-prescribers (doctors) they just don't seem to have great quality control, so you have to rely on your judgment when choosing one. (2/N)
