Function Order: Ne-Fi-Te-Si
Barney has a lot of hair-brained schemes and notions, and often makes up the biggest, most incredible scenarios as justifications for his behavior. When Andy tries to swindle him into not going to a dance with a pretty girl (so Andy can take her), he talks about the need to hire a temporary deputy for the day to watch out for pickpockets. Barney doesn’t like the sound of that, and in ten seconds flat, the possibility of a pickpocket has become a ‘gang of outlaws’ that he refuses to let anyone else take the credit for capturing, because HE is the deputy here and won’t be cheated out of a big collar like that! Barney is easily swindled and duped, because he is so trusting and gullible. He often rushes into situations without fact-checking them first, winding up pulling his gun on innocent bystanders and his boss. Barney often over-estimates his own ability to remember things, such as when he boasts that he has memorized the entire rule book and asks Andy to test him on it. Andy asks what the first sentence is, and Barney pulls a total blank. He then asks for the first word. After five agonizing minutes of having no clue what he just read ten minutes ago, Barney still boasts that he knows his stuff. Other evidence of his inferior Si is his general incompetence in the sensory world (trying to get out of a police car half-blocked by being parked too close to a mailbox, or locking himself and/or his boss in the jail cells with the keys just out of reach, or walking into traffic whenever he’s upset). Though eager for approval and somewhat arrogant, Barney also has a lower Te tendency to insist on living by ‘the rules.’ He’s much harder than his boss in arresting people for minor infractions, because the rule book says it’s a must. This means he sometimes locks up everyone in town while spouting off penal codes. They often argue about this, and about his use of ‘excessive force.’ Barney will just point to the rule book, and insist it’s what they should do, because it’s written right there.
Enneagram: 6w7 so/sp 
Barney tends to think in worst-case scenarios and doom things before they have even happened; when he finds out Andy’s girlfriend is rich, he immediately lays out a bunch of reasons why Andy should break up with her, because it’s not going to work out (he’s wrong about all of it), all out of ‘concern’ for his friend ‘being hurt’ by a rich girl. He acts confident and over-assertive when given important jobs to do, but just as fast, becomes reactive, aggressive, and angst-ridden whenever his authority is challenged. He will immediately bend the knee to superior authorities, such as the mayor, or the governor’s office, and anxiously get on Andy for breaking the rules, or not following a procedure, or ignoring the advice from ‘higher-ups.’ He also shows a strong line to 3, in that whenever he is under stress, he becomes defensive of his ego, insistent upon being acknowledged for what a good job he does, arrogant in an attempt to impress people, and defensive about criticism (all the while, over-reacting to any perceived slight or insult). His 7 wing avoids too much commitment; he dates several girls even if he’s serious about Thelma Lou, out of a fear of commitment and a desire to “keep them guessing” (about whether or not he’s going to be available). Barney is wildly reactive, outgoing, and sometimes over-confident to compensate for his insecurities, but ultimately wants to do a good job for Andy. He feels terribly guilty if he isn’t loyal to him, and stands up for him on several occasions when others are criticizing Andy, even if he doesn’t always agree with his methods.
