I was like that for a while until I lived with 4 other people who would often accuse me of caring too much about semantics (although semantics often had nothing to do with it... had to let that slide too).  I started doing the following:<p>1) Hear something incorrect.<p>2) Can I immediately tell that this incorrect fact will change the conclusion.  If so, correct the fact.<p>3) Else, let the conversation continue but remember the incorrect fact.  Keep looking out to see if it changes any conclusions.<p>I started doing this consciously and eventually its become fairly automatic.
