Even if it is the minority (from my anecdotal understanding it isn't) it would become like toxic waste in a professional community.
Also how would you even survey that? "Do you have zero disregard for objective truth and only interpret things to gain political capital by in-group signaling?"
Why not a survey given to undergrads of if they think this is the case? If you can detect this is going on surely others in your position could too.
You could also find a way to analyze the results of research produced now vs before in a particular field. Not sure how that would work necessarily
If the only way to measure this is someone's individual's general opinion, then the premise may be flawed from the start.
I am not saying it IS the reason. Just surmising that it might be. If you feel the need for a survey and review to think things then that is admirable but time is not in your favor.
In any case, this is not a statistical argument, and your comment adds nothing but noise to the discussion.
