I'd have to disagree with your Shaver, at least later in the game when skill points are in abundance and mind-reading can be trained to level 15 (no XP cost at all). At the very least it saves you some time loading and saving each time you want to mindread someone.
I'm already at level 46, and I haven't even found the fifth clue yet, I don't think I'd be as high if I was mindreading everyopne for full XP cost. But you make a good point - the game implies that mindread becomes more effective with increased skill, which isn't the case.
