I agree with Delvo, too. One more physical example is Baltar pulling on his own tie as Harvey-Six was doing that.

Baltar is an intelligent man. I'll accept the idea that Harvey-Six is his subconscious, and is telling him things that he has subconsciously picked up on. Her assurances are just what Gaius needs to hear to do what he should. I also think that sometimes he's just lucky, like with Doral in the miniseries. Or even with Lee saving his butt in the latest episode.
