In terms of other people's perspective, oh, I see the value. When I was in college studying psychology, it's actually something we're taught to do to relate to patients. I've had to empathize professionally with people whose actions would make your stomach churn, I'm very familiar with the concept and the psychological mechanisms at play and the need for such open mindedness.
I'd absolutely want to see this question brought up by a professor in a class, but I think it's not very well fit for a 13-14 year old's university entrance exam. You can't possibly expect someone of that age to provide a nuance balanced answer so I don't think it's a good quality signal for an openness trait. In fact there's test for openness that have been devised by professionals, so if the university wanted to select for it, they could more objectively measure it. Based on this, I think we can agree the question is not very good for measuring openness.
To be clear, for older people this can be a good entrance question since it shows whether their inherent openness was developed or not. Given the context (13-14 year olds) one of 3 reasons you gave for using it is mostly gone.
Then you're left with it's value as an intelligence estimation. IQ tests are the gold standard for estimating intelligence. Since this type of question doesn't appear on IQ tests (for reasons that to some of us are really obvious), it also stands to reason it's not a very good question for that. So we've removed the 2nd reason you listed to ask it in an entrance exam.
Last in terms of communication, it would seem this type of question will result in very biased grading from the professors. To test the ability to communicate most academics use non-controversial topics. So again, not very useful for the purpose you state.
There was a specific decision to choose a pro-authority question to use for an entrance exam. Could this be random? Possibly.
But it seems in line with a current trend to select for obedience over competence. Since it's not particularly useful to it's stated purpose (as we've gone over) it makes sense it raises eye brows and it makes sense people question it. If there was no such trend, or if professionally developed test designed to objectively measure openness or IQ tests didn't exist, you'd have more of a point.
Notice how my language uses words like 'seem', 'appears', 'it would be reasonable', etc. I'm not saying I'm 100% right. I have a very nuanced and probabilistic point of view. But the parent comment I was answering to if you RTFA and RTFT and follow the conversation that you are jumping into, suggested that even thinking such a question to be controversy is mere 'ignorance'.
I believe I provided a reasonable argument against what I was answering to. And instead of continuing the thread with the kind of carefully crafted language and nuanced that I present, you ironically and sort of pedantically explained why it's important to consider other points of view without really getting my point. If someone doesn't agree with you, or if someone doesn't laugh at your joke, it isn't always because they didn't get it.
I highlighted the fact that you used the word 'causes' since it seems to highlight your lack of through thought toward answering my point, which to me qualifies as "reacting to the surface level of any ... topic". You seem more ready to answer than to understand. That's why I found it ironic and limited my original response to that part. Now since you insisted, you have my full perspective.
