Reference: Elliot Aronson, Harvard University in 1966 - discovered the pratfall effect with Ben Willerman and Joanne Floyd. Experiments with high performing students and likeability. One spills coffee over a new suit, which enhanced their likeability when committing this 'pratfall'.
Insight: The admission of weakness can make people or companies more appealing.
Insight: The pratfall effect works well for companies where the competitors like to brag.
Insight: The pratfall effect only works when you are seen to be an expert, or strong brand - it makes strong brands stronger, and weak brands weaker.
Principle: Lean into your flaws (when it suits your brand).
Reference: Elliot Aronson - coffee spilling experiment. Spilling coffee hurt the likeability of the average (or incompetent) person, but enhanced the likeability of the expert - making them appear more human and approachable.
Insight: Expressing vulnerability is only effective if you are seen to be competent or an expert.
Insight: People prefer experts over less competent people, and pratfalls are not effective for incompetent people.
Insight: The self esteem of the people that view pratfalls has an impact on their effectiveness - audiences with very high or low self esteem respond less favourably to audiences with average self esteem.
Definition: The phenomenon where the occasional slip-up can enhance likeability.
Insight: The Pratfall Effect works only when someone is in danger of being seen as too perfect.
Reference: Elliot Aronson, University of California - conducted a number of experiments including the effect of knocking a cup of coffee onto a new suit on a persons likeability. The student committing the blunder was viewed as more likeable.
Definition: People have a tendency to like a person more after they make an everyday mistake.
Example: We tend to like actors more after seeing their blooper reels.
Example: We tend to like politicians who admit that they were wrong.
Reference: Elliot Aronson - studied the effects of "blunder" on likeability.
