Studies of these questions began with the interest in hypnosis aroused by the French physician Jean Martin Charcot (a teacher of Sigmund Freud) toward the end of 19th century. Charcot believed that only hysterical patients could be fully hypnotized but this view was soon challenged by two other physicians, Hyppolyte Bernheim and A. A.

Continuous repetition of instructions has shown that it can affect a person’s involuntary reaction. “The sociologists Gabriel Tarde summed it all up in the aphorism: “Social man is a somnambulist.””(Asch, 1955, p.1).
An experiment was conducted by simply asking opinions and references to a group of college students concerning various matters and on the latter part, subjects were asked again to state their choices but this time, they were also informed by the opinions of large groups or authorities. According to Asch (1955), “many subjects apparently shifted their judgements in the direction of the views of the majorities or the experts”(p.2).

According to Asch(1955)”when a moderate dissenter is present, the effect…decreases by approximately one third, and extremes of yielding disappear…Most of the errors the subjects do make are moderate, rather than flagrant”(p.4).
Further, Asch(1955) states that “[l]ife in
