If you are familiar with the cast Friends, you know that they all have very distinct personalities. You can clearly see who is high/low within all of the big five personality traits They are all very outgoing, don't mind talking to strangers, and enjoy being in groups of people. Joey is especially high because he will talk to any woman he finds attractive and likes the celebrity lifestyle with all the parties that comes along with his role in Days of our Lives. The next characteristic is agreeableness. Rachel is very high in agreeableness. She is always there for everyone when they need advice; she is an affectionate person and gets along very well with others. Monica is a good example of someone who is high in conscientiousness. She is very organized and pays close attention to detail. This is very prevalent in the fact that she is obsessive with cleanliness and everything has a certain place where it belongs. Ross is especially high in neuroticism. He is depressed a lot and having a not-so-ideal life. He is made fun of because of the fact he has had multiple failed marriages and got fired from his job because he over reacted to someone eating his sandwich. Phoebe is the one that comes to my mind when I think of openness to experience. She tries a lot of new and different things that most people wouldn't. She is very unconventional in the way she lives her life and is intellectually curious.
The link provided is an example of why I believe Ross is high in neuroticism.
