A MindSnap feature
Five turning points, one per flagship collection: Constantinople 1453, Socrates in Athens, the tulip collapse of 1637, Milgram's laboratory and the first Impressionist show. You choose, you get a verdict, and then you read what actually happened and why it still matters.

Athens, 399 BC
A MindSnap feature
A jury of 501 Athenians has convicted you of impiety and corrupting the youth. You are Socrates, seventy years old. Tonight your friend Crito sits in your cell: the guards are bribed, a boat waits, Thessaly will shelter you. The sacred ship returns from Delos tomorrow, and when it docks, you drink the hemlock.
Make the call
Reading that Constantinople fell is information. Choosing where to put your last reserve, and then finding out, is an experience with a stake in it. Decision-first learning works because the answer arrives as a resolution to something you personally committed to.
Every outcome explains the machinery underneath it: why morale behaves like ammunition, why a fleet inside the Golden Horn changes the arithmetic of a wall. You leave with a causal model, not a date.
Counterfactuals are guesses and we label them as guesses. Where historians disagree, the scenario says so. The 'What really happened' panel is always the documented record, written with historians.
