Related to this idea is the idea of partial outs. For example, in situations with a very wet board, a card that that helps your hand could help your opponent as well. In that case, when you are counting all your outs you can discount the outs that you aren't sure about.
Example: You have cards that could make you a straight on the river, but it's possible that some of those cards could give your opponent a higher straight or a flush. You could count cards that would improve your hand but might also help your opponent as 0.5 outs each.
Half an out may not sound like it's worth worrying about, but if your bet closes the action, even half an out might mean the difference in whether or not you're getting the odds to draw to your straight.
