Every day, five real historical charts — cut in half. You see the past and draw what you believe happened next. Then reality traces over your line and scores how clearly you see the world.
Smoking rates, solar costs, internet adoption — a real dataset, cut at the midpoint.
Trace the second half with your finger. Forgiving by design — it's about the shape.
Reality is traced over your line and scored — then see how you compare to everyone today.
Most people are wrong in the same direction.
Five real charts every day — the same set for every player on Earth.
Sourced from public records. No accounts, no ads, no tracking.
