Uppdrag granskning och sveket mot våldtäktsoffren Yours truly såg idag ett intressant avsnitt av SvT:s Uppdrag granskning. Programmet handlade om att män födda i utlandet är kraftigt överrepresenterade bland de som dömts för att ha begått våldtäkt i Sverige — och, enkannerligen, om varför ledande svenska politiker och brottsforskare inte tyckt att det har varit viktigt eller speciellt intressant att statistiskt belägga våldtäktsmännens etnicitet.

Before running an experiment, investigators should consider what they believe the chances are that they are testing a true rather than a non-true relationship. Speculated high R values may sometimes then be ascertained … Large studies with minimal bias...

They are, of course, entitled to have whatever views they like — after all, it is, to say the least, difficult to empirically disconfirm the non-existence of Gods … But for the rest of us, let’s see how rational expectations really fare​ as an empirical assumption.

“I never learned maths, so I had to think” Professors may find themselves ill-prepared for the macro classroom. To become academics they had to answer erudite questions posed by more senior members of the discipline.
