One is over-estimating what you know and are capable of. The other is, under-estimating. The former is a problem because it often comes from a lack of self-awareness (and peers willing to speak up when you faulter). The latter can be a problem because it prevents you from fully offering what you have to offer. Of course there's a sweet spot, but if you had to favor one or the other, lean towards Imposter. When you're in DK-mode you're far more likely to make "bad yeses" and those can be painful.
