Describe Cialdini's (1994) six basic principles for gaining compliance.

These six principles are:
   1) Friendship/liking - we tend to more willingly comply with those we like or are friends with
   2) Commitment/consistency - we tend to be more willing to comply in ways that are consistent with a commitment we've already made
   3) Scarcity - we tend to value scarce outcomes and objects. As a result, we are more likely to comply with requests that focus on scarcity.
   4) Reciprocity - we return favors via compliance.
   5) Social validation - we are more compliant when compliance is consistent with what we believe similar others are doing or thinking. This is may be considered as a form of being correct.
   6) Authority - we tend to comply more readily with requests that come from someone who we believe to hold legitimate authority over us.
