Fig 13. Individual accuracy against the number of shared estimates τ, before (filled dots) and after (empty circles) social information sharing, in the Random (black), Median (blue), and Shifted-Median (red) treatments.
The population was separated into subjects’ answers where the average social information received M was lower than their personal estimate Xp (D = M − Xp < 0) and subjects’ answers where the average social information received was higher than their personal estimate (D > 0). Solid and dashed lines are model simulations before and after social information sharing, respectively. Individual accuracy improves marginally for D < 0, but substantially for D > 0.
