Experiment Set-Up for Study of How Social Information Amplifies the Tendency to Gather Insufficient Data
In order to test the effects of social learning on individual learning the study had participants do a probabilistic reasoning task, the bead task. All participants were told that the urn full of beads either had 40 pink beads and 60 green or 40 green beads and 60 pink beads and their goal was to guess the correct majority. Money would be given to those who guessed correctly in order to incentivize the participants. The participants could choose to look at the colors of 0-15 beads, however the more beads they picked, the more money was subtracted from their $.15 endowment. The control group completed this task without any given social information of the other participants’ actions. The experimental group was provided social information (irrelevant to the actual answer) that only told them how many beads had been drawn by the previous participant, the colors of those beads were not included in the information.
