"Thinking about wine can make you less inhibited."
According to a study in the journal Current Directions in Psychological Science, the power of suggestion has more effect on outcomes than most people -- even in scientific fields -- tend to think. Researchers compared "response expectancies" to the placebo effect, demonstrating that the simple suggestion of something like a lucky rabbit's foot or a relaxing glass of wine can influence actual behavior -- the expectation of an outcome, in other words, makes you unconsciously behave in a way that makes that outcome more likely. The effect isn't even limited to deliberate suggestion; police lineups, for example, tend to yield more false IDs when organized by someone who knows who the suspect is (again, a case of anticipation unconsciously influencing actual behavior).
