ISI is where a person conforms to gain knowledge, or because they believe that someone else is ‘right’.
ISI is shown in the variations by Asch for taskdifficulty.
An example of ISI is when someone conforms when they are unsure of the correct answer; a student may copy their peer if they do not know the answer to a maths question.
ISI happens when people are uncertain of how to behave so look to others and conform.
