The The Big Bang Theory cast, sorted

The Big Bang Theory is a sitcom about brilliant people who are bad at being people, and about the one neighbor who is better at it than all of them. That premise is also the source of its most durable argument. Does the show laugh with its scientists or at them? Fans split on it, and the split tells you which character you root for.

Sheldon is the engine. He is rigid, literal and convinced he is the smartest person in any room, and the show spends twelve seasons letting that certainty collide with other people's needs. Leonard is the person who absorbs the collision. He accommodates Sheldon, apologizes for him and rarely says no. Watching them, viewers divide on a plain question: is Leonard a good friend or an enabler? The show suggests he is both.

Penny is the audience's way in, and her story is quieter than it looks. She arrives as the neighbor with the cheerful, practical sense and no safety net, and she spends years looking for what she is good at. Fans often argue about whether she is the show's heart or its punchline. The better reading is that she is the one character who keeps paying the real cost of other people's eccentricities.

The supporting four widen the map. Howard and Raj are friends who treat each other as the only people who will tell the truth, which is why they often do not. Bernadette begins as a sweet colleague and turns out to be the most formidable person in the room. Amy is Sheldon's equal in intellect and, to the show's credit, in obstinacy. Stuart, who runs the comic book store, is a reminder that talent and luck are different things.

Over twelve seasons the show also changes shape. The early years are about the gap between the apartment and the hallway, between people who understand physics and people who understand people. The later years are about what happens when that gap closes through marriages, careers and children. Fans who prefer the early seasons tend to prefer Sheldon unchanged. Fans of the later ones tend to prefer him changed. Your result may tell you which kind of fan you are.

This quiz works from everyday choices rather than catchphrases. You will be asked what you would do when a friend has a bad date, when a gift needs choosing, when a rule threatens the evening. Each answer points toward the character who would most likely make the same call, and the highest total wins.
