Asch Conformity Experiment

Experiment Overview

• An experiment differs from a public opinion poll:

  • It examines behavior under social pressures.

  • Cultivated through the work of Solomon Asch.

Purpose of Today’s Experiment

• Involves the perception of line lengths:

  • Participants will compare a line on the left with three lines on the right.

  • Task: Identify which line on the right matches the line on the left in length.

Experiment Structure

• Participants will give answers in a specific order:

  • The real subject is the fifth person wearing a white T-shirt.

  • Other participants are Confederates, instructed to provide incorrect answers on some trials.

Initial Responses

• Experiment starts without incident:

  • Answers given: two, two, two, two, two; then three, three, three, three, three.

  • On the third trial, a pivotal moment occurs:

  • The real subject denies their own judgment.

  • They yield to group influence despite their own perceptions.

Key Findings

• Asch's conclusions on conformity:

  • Subjects conformed on 37% of critical trials.

  • Reasons for Conformity:

  • Distortion of Judgment:

    • Belief that the group is right (i.e., "They must be right; there are four of them and one of me").

  • Distortion of Response:

    • Awareness of correctness but yielding to avoid discomfort (i.e., "I know they're wrong, but why make waves?").

Variation with Partner

• Asch's variation with a partner:

  • A partner in the third position provides the correct answer.

  • Result: Yielding drops to 5% of critical trials when a partner is present.

  • Subjects report positive feelings towards the partner but typically do not acknowledge the partner's influence on their independence.

  • Implication:

  • The power of the group is increased by unanimity.

  • When this unanimity is disrupted, group pressure diminishes significantly.

Types of Conformity

• Informational Conformity:

  • Conforming because the group’s information appears convincing or correct.

• Normative Conformity:

  • Conforming to avoid disapproval or discomfort from the group.

Additional Variation

• Asch's private response variation:

  • Subjects instructed to write answers due to late arrival.

  • Exposure to misleading information remains the same.

  • Outcome:

  • Reduced pressure to conform leads to a 23% drop in conformity rates.

Conclusion

• Asch's experiment is a seminal study:

  • Highlights human tendencies to deny personal perceptions and yield to social pressures.

  • Provides insights into the conditions that enhance or diminish conformity.
