This sounds like simple confirmation bias to me.
The number of times something interesting happens is probably much lower than the number of times something un-interesting happens. But the former are the only ones you notice, because they are interesting.
I would be very disappointed and surprised if he were setting up strawmen.
Harald Eia (the presenter) recieved his Candidate’s Degree (hovedoppgave) (= Bachelor’s/Master’s Degree?) in sociology according to Wikipedia. In one of Norway’s talk-shows (I don’t remember which) Bård Tufte Johansen, Harald’s close colleague, said something along the lines of “We [Harald and Me] can not make a comedy-sketch where humans are interacting with dinosaurs, because Harald would protest that dinosaurs died out long before humans existed. [Quoted from memory!]”. The point being that Harald Eia is very particular about scientific details.
He is also host of a TV-show called “Brille” (which I haven’t seen myself) which according to the Norwegian Wikipedia-page is similar in concept to QI.
