What function causes me to interpret things as what they logically should or could be and not what they are?

Typed as INTP.

I have a chronic, automatic habit of being overly charitable when interpreting an idea, theory, or statement.

I got through a whole degree in philosophy while acing any explanation of someone’s theory or argument, because in my mind the best / strongest interpretation of the argument simply was the argument.

I can seem stupid because someone might say something that others would think is logically contradictory, including emotionally, but instead I automatically interpret what they say to maintain logical consistency - rather than a contradiction in which the person is irrational.

For instance, if I often spent the entire day with my child and then they said, “You never spend time with me,” I would assume they mean they want to spend time with me during activities they usually don’t, like household chores or more mundane activities. Yet, most people would likely be upset at the child for being ungrateful and irrational.

What could explain this automatic process that happens for me? I forget which function is responsible for seeing the world in terms of possibilities, but perhaps it’s that combined with the logical consistency piece of INTP. But I’d like to hear about it in terms of the functions.
