The Society
Trains: Sunk cost
A 5-minute decision story: the society you co-founded is dying after six weeks. Quit clean, one more month, or a relaunch? Three choices, your reasoning recorded — and a debrief that names the mental model: sunk cost.
Episode 1, The Swap, is free — no account needed. Episodes 2–6 are included with the paid Trailblazer plan.
