The social proof strategy is based on the idea of normative social influence, which says that people will adapt to be liked by others and accepted by society.
We gave the respondents fictitious information that 80% of people peel a banana from the backside, expecting that information will influence their choice, although this information is untrue. We call this the social proof effect.
Although respondents saw information that 80% of people do something differently, they chose to stick to their habits. Social evidence does not work if it does not give a concrete benefit that will bring the consumer something better, something worth giving up the habit.
