How are confidence and optimism atypical for ENTPs?
ENTPs are optimists. They tend to regard problems as personal challenges, and have little patience with those they consider wrong or unintelligent. However, they are often extremely genial and quite charming, when not being harassed by life in general.
Good at analysis, especially functional analysis, ENTPs have a tolerance for, and enjoyment of the complex. Enthusiastic, ENTPs are apt to express interest in everything, and thus unwittingly inspire others who find themselves caught up in an ENTP idea. The ENTP is the most reluctant of all types to do things in a traditional manner.
