This birth order quiz asks how you handle group projects, road trips, birthdays and the last slice of pizza, then makes a playful guess at whether you're the oldest, a middle child, the youngest or an only child. It's a fun guess, not science, so don't be surprised if we miss. Send it to your siblings and see who we pegged right.

Why birth order makes such a fun guess

Ask a room full of people about their siblings and you'll hear strong opinions fast. The idea that birth order shapes personality goes back to the early 1900s, when Austrian psychiatrist Alfred Adler suggested that a child's place in the family could influence how they see the world. The theory stuck around in pop culture, and today almost everyone has a hunch about how their spot in the family shaped them, or how it explains their siblings.

The science is much less certain. A large 2015 study of more than 20,000 people in the US, Britain and Germany found that birth order had no meaningful effect on core personality traits such as how outgoing, agreeable or conscientious people are. That's exactly why this quiz is a playful guess rather than a test. Each of the seven questions has four answers, and each answer quietly leans toward one of four family roles. We tally your picks and make our best call.

There are no wrong answers, so go with your gut. If we get it wrong, that's part of the fun, and it might just prove you're one of a kind. Share it with your brothers and sisters and see whose guess lands.
