The AIDS example here is using a known AIDS/HIV denialist (who is also not a medical doctor, but a psychoanalyst), and does not represent the consensus view at the time. That same year, the NIH and Department of Health and Human Services had announced that there was a probable link between a virus (HTLV, later HIV) and AIDS [1]. There are always some denialists or crackpots out there, but I don't think your examples necessarily show that doctors are lazy and default to psychogenic means.
