Pratfall effect

Pratfall effect is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pratfall effect rather than just read about it. In short: In social psychology, the pratfall effect is the tendency for a person's likability to change after making a mistake depending on perceived competence: highly competent individuals tend to become more likable, while average individuals may become less likable for the same error.

Key takeaways

  • Pratfall effect belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pratfall effect to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

In social psychology, the pratfall effect is the tendency for a person's likability to change after making a mistake depending on perceived competence: highly competent individuals tend to become more likable, while average individuals may become less likable for the same error. Originally described in 1966 by Elliot Aronson, numerous studies have since been conducted to isolate the effects of gender, self-esteem, and blunder severity on change in appeal and likability. Occasionally referred to as the blemishing effect when used as a form of marketing, generalizations of the pratfall effect are often used to explain the counterintuitive benefits drawn from making mistakes.

Research The pratfall effect was first described in detail by Aronson, in his 1966 research of a simple blunder's effects on perceived attraction. The experimental subjects consisted of male students from the University of Minnesota. Participants listened to tape recordings of actors pretending to be contestants on College Bowl, staged interviews with difficult questions given to an actor, who plays the role of either an unrealistically knowledgeable individual who almost always answers correctly (92%) or a mediocre one who answers only a few questions correctly (30%). After the questioning, the strong-performing actor admits to a stellar high school career marked with academic and nonacademic successes, while the unremarkable actor describes an ordinary high school career, earning average grades with weak involvement in extracurriculars. At the end of the interview, some tapes recorded the actor spilling a cup of coffee and apologizing for doing so, while others omitted this portion to serve as a control. Aronson's research found that a knowledgeable blunderer was rated to be more attractive, while the more average ones suffered decreases in their perceived attractiveness. Later research inspired by Aronson experimentally defined appeal as a combination of liking and respect and replicated similar results. A research study showed that making a clumsy mistake increases the appeal of an exceptional individual whereas making the same mistake seems to make an average person less attractive. Additionally, these findings were anticipated based on the hypothesis that although a mistake helps to humanize someone and boost their appeal, a superior person may be perceived as extraordinary and aloof.

Sex In a 1972 study by Kay Deaux, male participants were swayed more strongly by the pratfall effect than women.

Severity of pratfall Research by Mettee and Wilkins reveals that the severity of pratfall plays a major role in determining attractiveness after a pratfall is committed. Experimentally, each condition was conveyed by changing the response of the interviewer and blunderer:

Control condition: No blunder. Minor pratfall condition: The sound of a cup spilling is heard and the actor reacts with anguish. Major pratfall condition: Cup is spilt, and the interviewer reacts with hostility toward the actor, who apologizes profusely. An able individual who commits a minor pratfall (2) will have an insignificant decrease in average liking and a small decrease in average respect, while the able individual who commits a major pratfall (3) will receive a significant increase in liking and an insignificant decrease in respect. A less able individual who commits any pratfall (2,3) will have a decrease in liking, which increases with the severity of the blunder. Respect only decreases in the less competent individual after a minor mistake is committed.

Self-esteem Research conducted on self-image suggests that self-esteem influences whether positive aspects of the pratfall effect and self-comparisons will occur. An individual with high self-esteem will prefer the non-pratfalling highly able individual to the pratfalling individual of equal ability. This is well explained by social comparison theory which investigates the tendency to compare oneself to others with similar capabilities. When an individual of similar competency to a rater commits a pratfall, the relatability between the observer and blunderer can cause mental discomfort which then results in lower likability ratings. Since observers seek to build accurate self-evaluations, the commonality shared between the blunderer and the observer could threaten the observer's self-concept, especially in self-evaluations of abilities. A rater with a high level of self-esteem would therefore feel threatened by a blundering competent individual, therefore preferring the non-blundering able individual since that individual poses no threat to the observer's self-esteem. For the same reason, an average blunderer would pose more of a threat to an average individual, resulting in similar losses in likability. Individuals with low self-esteem tend to prefer highly able individuals. Although no research has been conducted on this topic, one such explanation suggests that a person with low self-esteem would expect to be "outshone", and desires to find relatability between themselves and the perceived competent individuals.

Attitude Kiesler and Goldberg proposed that similarity in attitude between observers and blunderers can determine the extent at which changes in attractiveness occur. Greater similarities in attitudes resulted in more derogation, even to the point where the blunderer is subject to derogation regardless of perceived ability. This was determined experimentally by directly telling observers that they were extremely similar to the actor, especially in prose and in the form of responses to questioning. This research implies that similarities in attitude can be more significant in determining attractiveness, especially with the knowledge of congruence in attitude.

Worked examples

Example 1 — a first encounter with Pratfall effect

Start with the simplest possible case. Write down what Pratfall effect claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pratfall effect before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pratfall effect ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pratfall effect

In research
Pratfall effect appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pratfall effect in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pratfall effect is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cognitive biases, Interpersonal attraction, so understanding it makes those chapters shorter.
In everyday life
Look for Pratfall effect outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
