About this

A small quiz that places you in one of six archetypes — for survival, or for travel, depending on which one you took — then tells you whether you and the people you'd take it with are actually compatible.

It's a model. Models are useful. They're not the same as truth.

The archetypes are loosely descended from two real bodies of research.

Belbin's team-role research. Meredith Belbin spent decades studying which combinations of personality types make teams succeed or fail. His original nine team roles (Plant, Resource Investigator, Coordinator, and so on) are the intellectual ancestor of every “what role do you play in a group” framework, including this one. Belbin's specific roles have been critiqued — psychometrically, they reduce to Big Five personality factors when tested rigorously — but the idea that group success depends on role coverage, not just individual ability, is well-supported.

Palinkas and the ICE literature. Lawrence Palinkas at UCSD has spent decades studying small groups in Isolated, Confined, Extreme environments — Antarctic research stations, submarine crews, space-analog missions. The research is unglamorous and consistent: in survival contexts, the failure modes are predictable. Mental health problems, sleep disorders, factionalisation. Group structure (mesh vs. hub-and-spoke vs. cliques) matters more than individual capability past a certain threshold.

The compatibility math draws on small-world network analysis — the idea that you can describe a group's stability by looking at its weakest pairwise connection, its role coverage, and whether the people are arranged in a robust web or a fragile chain. None of this is novel. It's well-trodden methodology, applied to a slightly absurd premise.

• →Making you think specifically about the people you'd take into a hard situation
• →Naming dynamics in groups that often go unspoken
• →Producing results that are at least interesting to compare, and often surprisingly accurate to lived experience

It isn't a prediction. Real research on compatibility — particularly in close relationships — suggests that how people adapt to a situation matters more than how they measure beforehand. Compatibility quizzes correlate weakly with relationship outcomes in the literature. This one is unlikely to be the exception.

It also isn't a diagnostic. Your archetype isn't who you are. It's how you'd probably show up in this specific scenario, based on the answers you gave today. Take it next year and you might land somewhere else.

There are a lot of personality quizzes on the internet. Almost all of them tell you about you. This one tells you about your group — because what matters isn't whether you're a Captain or a Worrier, but who you're standing next to when things get hard.

That's the whole bet.
