The voyage runs in three steps.

Each scenario gives you two choices. Each choice updates your profile. At the end, the distribution opens.

One of 21 scenes.

The Arctic, frozen. 1923. Your turn.

S-AR-10 · Stakes

The eleventh week. Three days ago a recon team set out across the ice; they did not return by yesterday noon. The radio has been silent for six hours. The weather is hardening.

The decision is recorded.

A Send a search party. A backup sled team and four crew members will leave overnight.
B Wait until morning. Watch the weather report, listen to the radio. Decide at dawn.

What the reveal contains.

Frequently asked

Is this a personality test?

No. A test asks you; you describe yourself. ChoiceCodex does not ask — it watches what you choose across 21 scenarios. Behaviour says more than words.

How consistent are the results?

The same decisions yield the same distribution. The posterior is data, not a verdict; ChoiceCodex does not say 'you are X', it says 'in this voyage, the X pattern was dominant'.

Where does my data go?

In the anonymous flow, nowhere — only your browser. If you want to save your result, you create an account by email; your data is stored in Europe on Supabase. Not sold to third parties.
