When I see someBool == true, I can't help but feel like the programmer hasn't internalized the idea of evaluation, which is a pretty fundamental deficiency.

However, my perspective is skewed because I spent several summers in college teaching programming to kids, who frequently wrote expressions like this because they genuinely hadn't mastered the mental exercise of evaluating an expression. Once they grokked the concept, the redundancy became obvious.

For an otherwise competent professional programmer, this is probably not the case. It's probably just a bad habit they developed in their early days of programming and never quite shook. But it would still scare me a bit if it was the first thing I saw someone do in an interview.
