Leonard MBTI Personality Type
Personality
What personality type is Leonard? Leonard is an INFJ personality type in MBTI, 1w9 - so/sp - in Enneagram, in Big 5, SEI in Socionics.
His tactics worked so well on Eric because his Ti placement is just higher, so it made it easy for him to manipulate Eric's personal judgment. I suspect Eric would have been at a better placement if he tried to pry at Leonards's reasons for putting the family in harm's way by prodding at his past. But he never leveraged his Fe or Si against them for his compromised mental state, which I suspect was from the concussion. Manipulation of judgment and critical thinking didn't work on Andrew as Andrew has a higher Ti placement but, his lower Ni placement did get Andrew in the end, at which point he was very ready to shoot the love of his life. Clutch placements really.
