I think a bigger problem is that when a certain type appropriates the discourse of post modernism and finds themselves with a Ph.D, they then
claim expertise in entirely unrelated topics - like
childbirth, Postmodernism might have some quite interesting things to say
about the way the dominant discourse comes to be framed — don't think it would be terribly reliable on the way people react to risk — foregrounding the risks of things that are disapproved of, and minimising others.
