Research to support ISI as an explanation for conformity was conducted by Jenness. Participants were asked to privately estimate the number of jellybeans in a jar, decide on a group estimate, then take another private estimate. It was found that participants' second private estimate was significantly closer to the group estimate, than their own. Therefore supporting ISI as an explanation for conformity because when the participants were unsure of the answer, they sought information from the group and assumed it was right, which is what ISI suggests.
