Hmm, Si is a repository of detailed impressions. In some sense Si is the most patient perceiving function simply because they aren't as quick to make intuitive leaps like Ne/Ni and focus on more than what's immediately in front of them like Se. I don't think Si types rely on others' internal perception because theirs is so rich and detailed anyways. If anything, Si types might think that others' internal perception could be lacking to a degree.
ESTJs are likely to succeed at management because they respect structure and contribute to it. Most businesses thrive with an efficient and effective internal structure which ESTJs excel in. ESTJs can adopt the company values and incorporate them into their own. In some sense they become well groomed representatives of said company which is why companies entrust them with power.
How does reading from a teleprompter mean one sucks with Fe? Barack Obama has Fe and was able to wield it to increase his popularity from being a relative unknown in 2008 to becoming an icon for change and he still speaks with a teleprompter. In some ways Trump is following Obama's formula from 2008 but articulating himself much differently. Obama wanted to convey appealing ideological platitudes to the masses. He wanted his (staged)idealism to speak for him whereas Trump isn't so much about idealism but creating an indomitable presence and wants
that to speak for him. In a microcosm this could illustrate slight ENTP/ESTP differences in persona. ENTPs want to communicate with charm and ideas/platitudes while ESTPs want to communicate with shock value and their own powerful presence.
Trump might misfire and fall on his face but the difference with him and Hillary is that
he gains momentum from that and it confuses and frustrates the shit out of his detractors. When Hillary does it there is no rebound no silver lining, just utter failure and she changes her tune because there is not improv or contingency for the negative feedback. Trump doesn't let the political winds reshape his approach. Maybe some of his words are changed (such is the nature of politics) but his overall approach and presence remains in tact. Trump sort of has a 'mutually assured destruction' pact as well as a mutually beneficial pact with the media when you really think about it. When the media covers Trump it's guaranteed entertainment which means more eyeballs paying attention to their coverage. His presence brings eyeballs over. In exchange Trump gets more free media coverage than even the Clinton machine even if it's negative. Look at this thread even, lol. This started off as Hillary's personality type and it naturally gravitated towards Trump as well. Everyone looking this thread was also thinking 'Yeah, but what about Trump?"
Oh forgot to add, the destruction aspects shows when the media attacks Trump they also expose themselves because in order to attack him properly they need to forgo their phony mask of objectivity and show they are just as manipulative as the man they are attacking.
