There appears to be an ongoing debate at regarding Barack Obama’s personality type (look at the comments). They also have the profiles of past presidents and current candidates. What’s interesting is that they have him pegged as an INTJ, which is the mastermind personality type and not the idealist that everyone is making him out to be. This makes sense when looking at his excellent analytical performance in interviews as well as his emotional cool.Just look at the S.F. Chronicle interview with Obama and watch has he calmly answers questions in a coherent and point-by-point way that appeals to the intellect.
