Institutions like people have beliefs and positions irrespective of these positions relationship with reality. For example the FBI which would would reasonably expect to be experts in scientific analysis spent decades sending experts to testify as to the nature of matching hair that was left at crime scenes with real live suspects. Turns out that upon review 95% of the cases in which they gave testimony were flawed and they notably couldn't reliably tell dog hair from human hair let alone identify suspects. Just think of it people got 4 year degrees in a scientific field and built entire decades long career pretending to do something effectively not only to others but to themselves and their superiors. They testified in court dressed up in fancy suits with fancy titles when they were less effective at doing their job than a magic 8 ball. It would be like finding out your doctor wasn't exactly clear on the difference between a liver and a kidney and him and all his colleagues were just kind of faking it and hoping you wouldn't notice. The only saving grace that made them look sort of effective was the fact that they quite frequently but not always had ample evidence against the suspect meaning they were far more than average sending them hair samples of people who were in fact already known to be the real killer so they could in theory appear somewhat accurate by for example always saying yes if the hair was the same color which is you know fantastic for black people. Why would we expect a field of endeavor that is entirely isolated from any accountability to be good at anything?
