After learning an outcome, we reconstruct our memory to believe we "knew it all along." The past is rewritten to seem predictable. Click to reveal the outcome—watch how one path becomes "inevitable" while equally-likely alternatives fade into implausibility.

Click "Reveal Outcome" to see how knowing the ending rewrites the past.

Before knowing: 8 possible futures, each 12.5% likely. No path seems more "obvious" than another.
