You don't have to lack skills on one side of dichotomy to prefer the other.
The whole idea of an Fe approach to a math problem is kinda absurd.
Yeah. I think it all comes down to what motivates someone to do well. I have known Fe-doms to do something that they hated or was difficult for them because they were able to re-frame it. They may have wanted good grades, wanted to please someone important to them (or above them), etc, and that was sufficient to do well even if they lacked interest or aptitude.
I didn't oversimplify anything. I described people I knew. Some of you are misinterpreting that as a description of types.
I was responding to:
It's difficult for me to imagine what an Fe often goes through when broaching a math problem. But from what I understand, the Fe tries to humanize everything. Imagine if you would a rising sun emanating happy little rays of light and with a smiley face drawn on it, and myriad other examples.
An EFJ approaching a math problem would just use Thinking (and iNtuition). They're not somehow limited by their preference for Fe in the average situation. It's not like an Fe dom can't realize that Fe isn't going to solve the problem for them...
If you really like hammers and someone asks you to tighten a screw, you're not gonna freak out because you can't use a hammer -- you'll just use a screwdriver.
