Pollyanna principle

Pollyanna principle 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 Pollyanna principle rather than just read about it. In short: The Pollyanna principle (also called Pollyannaism or positivity bias) is the tendency for people to remember pleasant items more accurately than unpleasant ones. Research indicates that at the subconscious level, the mind tends to focus on the optimistic; while at the conscious level, it tends to focus on the negative.

Key takeaways

  • Pollyanna principle belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pollyanna principle to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pollyanna principle from memory before moving on to harder problems.

Reference excerpt

The Pollyanna principle (also called Pollyannaism or positivity bias) is the tendency for people to remember pleasant items more accurately than unpleasant ones. Research indicates that at the subconscious level, the mind tends to focus on the optimistic; while at the conscious level, it tends to focus on the negative. This subconscious bias is similar to the Barnum effect.

Development

The name derives from the 1913 novel Pollyanna by Eleanor H. Porter describing a girl who plays the "glad game"—trying to find something to be glad about in every situation. The novel has been adapted to film several times, most famously in 1920 and 1960. An early use of the name "Pollyanna" in psychological literature was in 1969 by Boucher and Osgood who described a Pollyanna hypothesis as a universal human tendency to use positive words more frequently and diversely than negative words in communicating. Empirical evidence for this tendency has been provided by computational analyses of large corpora of text.

Psychological research and findings The Pollyanna principle was described by Margaret Matlin and David Stang in 1978 using the archetype of Pollyanna more specifically as a psychological principle which portrays the positive bias people have when thinking of the past. According to the Pollyanna principle, the brain processes information that is pleasing and agreeable in a more precise and exact manner as compared to unpleasant information. People actually tend to remember past experiences as more rosy than they actually occurred. The researchers found that people expose themselves to positive stimuli and avoid negative stimuli, they take longer to recognize what is unpleasant or threatening than what is pleasant and safe, and they report that they encounter positive stimuli more frequently than they actually do. Matlin and Stang also determined that selective recall was a more likely occurrence when recall was delayed: the longer the delay, the more selective recall that occurred. The Pollyanna principle has been observed on online social networks as well. For example, a series of studies by Emilio Ferrara, a computer scientist at the University of Southern California, found that Twitter users preferentially share more, and are emotionally affected more frequently by, positive information. However, the only exception to the Pollyanna principle tends to be individuals suffering from depression or anxiety, who are more likely to either have more depressive realism or a negative bias.

Positivity effect

The positivity effect is the ability to constructively analyze a situation where the desired results are not achieved, but still obtain positive feedback that assists one's future progression. Empirical research findings suggest that the positivity effect can be influenced by internal positive speech, where engaging in constructive self-dialogue can significantly improve one's ability to perceive and react to challenging situations more optimistically. The findings of a study show that the optimism bias in future-oriented thinking fulfills a self-improvement purpose while also suggesting this bias probably reflects a common underpinning motivational process across various future-thinking domains, either episodic or semantic.

In attribution

The positivity effect as an attribution phenomenon relates to the habits and characteristics of people when evaluating the causes of their behaviors. To positively attribute is to be open to attributing a person's inherent disposition as the cause of their positive behaviors, and the situations surrounding them as the potential cause of their negative behaviors.

In perception Two studies by Emilio Ferrara have shown that, on online social networks like Twitter and Instagram, users prefer to share positive news, and are emotionally affected by positive news more than twice as much as they are by negative news.

Positivity bias Positivity bias is the part of the Pollyanna principle that attributes reasons to why people may choose positivity over negative or realistic mindsets. In positive psychology, it is broken down into three ideas: positive illusions, self deception, and optimism. Having a positive bias increases with age, as it is more prevalent in adults approaching older adulthood than younger children or adolescents. Older adults tend to pay attention to positive information, and this could be due to a specific focus in cognitive processing. In studies compiled by Andrew Reed and Laura Carstensen, they found that older adults (in comparison to younger adults) purposefully directed their attention away from negative material.

Criticisms Although the Pollyanna principle can be seen as helpful in some situations, some psychologists say it may inhibit an individual from coping effectively with life obstacles. The Pollyanna principle in some instances can be known as "Pollyanna syndrome" and is defined by such skeptics as a person who is excessively positive and blind towards the negative or real. With regard to therapy or counseling, it is viewed as dangerous to both the therapist and patient.

Worked examples

Example 1 — a first encounter with Pollyanna principle

Start with the simplest possible case. Write down what Pollyanna principle 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 Pollyanna principle 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 Pollyanna principle 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 Pollyanna principle

In research
Pollyanna principle 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 Pollyanna principle 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
Pollyanna principle is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1978 neologisms, Cognitive biases, Figures of speech, so understanding it makes those chapters shorter.
In everyday life
Look for Pollyanna principle 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.
