Survey and experimental evidence are playing an increasingly central role in antitrust and competition matters, especially in cases involving consumer perceptions, competitive effects, or behavioral responses.

Senior Associate Dr. Animesh Giri recently authored an article discussing the conditions under which surveys and other experimental evidence produce reliable insight and when they do not. Drawing on the logic of the “wisdom of crowds,” there are two conditions necessary for reliable surveys: (1) respondents must share a common understanding of what is being asked; and (2) their individual errors – whether arising from imperfect recall, inattention, minor misunderstanding, or subjective judgment – must be uncorrelated.

The full article, “The Wisdom of Crowds and Reliability of Surveys,” is available below.
