Yes and very yes, respectively. And I have a very House-ian view of lying.
It also absolutely amazes me how bad people are at lying. Maybe being better at it makes you more perceptive, but people around me lie all the time and are incredibly bad at it.
Proptip: It really helps to think of lying less as coming up with a story and more as coming up with a layered contingency plan against investigation. You want to be playing Xanatos Speed Chess, not trying to be the Clock King. Truth be told, this does require a certain level of cool-headedness and quick thinking, but the alternative requires impossible foresight.
