Gryffindor's cardinal traits are bravery, pride, stubbornness and impulsiveness. Most people in the house of Gryffindor will be extroverted. (Remember, introversion is different than being shy: you can be a shy extrovert.) Gryffindors gain energy and life by being around people, grain strength from friends and enjoy working with those close to them. However, they are also emotionally volatile and can experience a wide range of feelings in a short amount of time, from unbridled happiness to deep depression to unrestrained rage. They are less emotionally stable than some of the other houses (such as Ravenclaw and Hufflepuff); Gryffindors are also impulsive. They're also generally good-hearted and trusting, and for the most part like people at first sight unless they are given a reason not to. Gryffindors are Prideful, bad at taking criticism and easilyget into conflicts with others—this is the main trait that would bring their overall level of agreeableness from high to average.

A Gryffindor's prideful nature coupled with their sense of justice and stubborn behavior causes them to be extremely set in their ways. They have a difficult time backing down from a fight or admitting that they are wrong. It's also very hard for them to get over a bad first impression or change their opinion on someone.
