I'm writing my CV now and was wondering whether I should indeed be "as confident as possible" (which basically means, according to some people, that I'm limited to sentences that don't even contain words like "but", "mostly", "although" etc.). Overconfidence is a killer of rationality, and displaying it might signal that you're irrational. I would personally trust much more someone who actively doubts in many things he says, rather than someone who is always confident. However, some people say the opposite.

I was wondering how should I approach my CV? Would it attract more rational employers if it's more self-skeptical? I'm not going to take it to a degree where it's as self-skeptical as I usually get when I give my honest advice on something (pointing out as many assumptions and dependencies on sources of information as possible, and sounding like nobody else I know, based on a very quick search). But still wondering whether this would get me a more irrational employer, and would some of you actually trust more someone who sounds confident.
