Soloman Asch conducted a series of highly influential studies in the 1950's on
conformity. In a typical study, subjects are shown a card with the figure below, and told
that the length of line “X” is exactly 6 inches. It is known that in the population, the
mean estimated length of line "B" is µ = 6 inches, when individuals are asked to
estimate the length of line "B" when they are alone.
