Evidence Accumulator Lab

Smart decisions without overthinking: let evidence stream in and stop when you’re sure. Balance accuracy, calibration, and speed.

10 rounds Evidence ~ every 250–350ms Score = Accuracy × Calibration × Speed Efficiency

Hidden truth is A or B. Each dot is a noisy clue. The middle bar shows accumulated evidence (left = B, right = A). Stop when it crosses your comfort threshold—or when the clock runs out.

Tip: Tight thresholds reward speed (more risk). Cautious thresholds boost accuracy but cost time.

Results & Learning

This mirrors drift–diffusion / SPRT ideas: accumulate small noisy updates until you’re confident enough to act.
