Raven Alpha: what it answers
40 runs, 981 responses, Oct 6 1:43 PM UTC to Oct 13 3:25 AM UTC. Each row is one fixed prompt with no right answer; the detector tracks the distribution of answers, not any single one. Filled cells: that run's most common answer was the overall favourite. Hollow cells: it was something else (normal for prompts with many good answers).
