How the score works

Predicted watch share + the difference from viewers, as a share of the full video. Capped at 0–100%.

100 × (2 × prediction − viewer median) ÷ video length.

An illustrative enjoyment score. The fly still likes at halfway when its prediction is at least 1 s above the viewer median.

0.0 s watched— remaining

Like at halfway if prediction ≥ viewer median + 1 s.

Dr. Buzz is a cartoon; this panel is recorded simulation, synchronized with the video. The anatomy shows sampled real neuron skeletons; region rates use all 166,700 neurons. Regions are broad annotation groups, including pathways and the ventral nerve cord. Brightness shows electrical firing, not dopamine concentration or a causal explanation of the prediction.
