INFJs control ideas sometimes.

That's how I see it as well.

...

Then again, INFJs can also be good at spotting when other people are trying to control ideas because INFJs often question even the most basic suppositions. I think I notice rather well when people lean to believe in some ideas over others just because it's fashionable in some niche. Even in scientific communities, some theory can become fashionable perhaps not because the theory is so good overall but because the theory was successfully implemented in some intriguing study. Suddenly everyone sees things through that one theory with little regard to if it fits to anything outside that one study. Also it makes you feel like you've been hoaxed when everyone are trying to sell you that one theory and then you dig a little deeper and see that oh, it's not that awesome after all. I should be able to trust scientific communities please step up your game!!1

I think it's also common to interpret texts in highly subjective ways while the reader doesn't realize they're doing that. I've been in seminars where it seems like people read into other people's papers whatever they want to read. It's not even productive because there are so many misconceptions that it would take forever to correct them so instead of constructive conversations you just end up nodding and being like "ok hehe thank you for your work I'll consider it".

Makes me think it's hard for pretty much everyone to be "objective". That'll probably take a lot of training your brains and years of experience. Plus people's memory is sometimes truly short. If you don't actively train critical thinking you might fall to the same old traps soon again.
