What is the personality type of Sid? Which MBTI personality type best fits? Personality type for Sid from Ice Age Franchise and what is the personality traits.
Sid personality type is ENFP, the same as most of the characters in this world. The part of their personalities that makes them feel like they're not good enough is most likely the inferior function.
ENFPs are famous for their need to be with other people, and in particular, with other ENFPs. It's not uncommon for ENFPs to become so obsessed with the idea of being in an exclusive group that they'll do anything possible to get in. They still think they're not good enough and that everyone else in the group will see that and leave them out. They then become obsessed with trying to prove that they're just as good as everyone else in the group, and start doing crazy things to try and gain the approval of the group.
The ENFP in your story may be causing all of this because he's insecure about his place in the group, even if he's sure he's better than everyone else. He may have done something to try and prove his worth, but he doesn't realize that no one will ever truly accept him because he doesn't think he's good enough.
I hope this helps.
