Seeing what other traders did raised the share picking the riskiest asset from 33% to 52%
Share of subjects choosing asset D, the riskiest of four, in the second block of a laboratory asset market experiment at the University of Heidelberg in 2017, 176 subjects. Information against baseline gives a Mann Whitney p of 0.014. Copying against baseline, counting copiers' intended choices, gives p below 0.001.
In a controlled experiment, 32.5 per cent of subjects chose the riskiest of four assets with no information about others. Shown others' outcomes the share rose to 47.9 per cent, and with copying available it reached 51.6 per cent.
