Answer:
d. even when the group judgment was clearly incorrect.
Step-by-step explanation:
Solomon Asch performed a series of experiments that are known by the generic name "the Asch experiment". This is a series of surveys conducted in 1951 whose main purpose was to prove that people submit to the power of the group, adopting a compliance attitude towards it.
The experiment basically consisted of forming a group of 7 to 9 students. All but one were part of the experiment and were accomplices of the researcher. A few lines were shown to all of them, and the researcher asked each to indicate which line was longer. The correct answer was very evident, but the accomplices begin one by one to speak the option that was noticeably smaller as if it were the correct option. This made the subject being actually evaluated - the only one who was not an accomplice - feel strong pressure from the group to respond.
In this experiment Asch reported that individuals were in agreement with a group's judgment of line length even when the group's judgment was clearly incorrect.
