Taking the Ti vs Te split.
If Ti is not problem solving then why are ENTPs and INTPs good problem solvers??
If Te is not based upon complete understanding then why is it that when you try and persuade an INTJ/ENTJs point of view or enlighten them to something you think they haven't seen do you always find that they've considered everything (usually to a limit of understanding gauged more on their individual intelligence and level of care taken)?
It always seems that the splits in the functions aren't well defined enough to really be of use. Maybe I've not found the pattern yet, I'm open to that.
