Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

93.2K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Hindsight Biases

4.1K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Revisionist Views of Adolescent and Adult Cognition

155
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Understanding Deception01:14

Understanding Deception

56
Deception is a pervasive aspect of human communication. Empirical studies have shown that most individuals engage in some form of deceit on a daily basis, with approximately 20% of social exchanges involving deceptive elements. Lying follows a developmental trajectory, peaking during adolescence and declining with age, possibly due to the maturation of cognitive control and social accountability.Cognitive and Social Factors in Deception DetectionDespite its prevalence, accurately detecting...

Cognitive Dissonance01:38

Cognitive Dissonance

35.4K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Confirmation Biases01:31

Confirmation Biases

7.5K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Summary
This summary is machine-generated.

Older adults may deliberately choose ignorance more than younger adults, potentially to regulate emotions. This study found age was the strongest predictor of choosing not to know information, even when beneficial.

Area of Science:

  • Cognitive Psychology
  • Gerontology
  • Decision Science

Background:

  • Individuals sometimes opt for ignorance despite low costs and high potential utility of information.
  • This behavior may serve as an emotion-regulation strategy, particularly in older adults.

Purpose of the Study:

  • To investigate if older adults are more prone to deliberate ignorance than younger adults.
  • To explore the role of deliberate ignorance as an emotion-regulation tool in different age groups.

Main Methods:

  • A representative sample of 1,910 German residents participated.
  • Participants were presented with 13 scenarios involving potential gains or losses from acquiring knowledge.
  • Age, openness to experience, risk preference, and neuroticism were assessed as correlates.

Main Results:

  • Age was the strongest correlate of deliberate ignorance.
  • Openness to experience showed a negative correlation with deliberate ignorance.
  • Risk preference and neuroticism did not consistently predict deliberate ignorance.

Conclusions:

  • Findings suggest a potential positivity effect in how older adults approach new, ambiguous information.
  • Deliberate ignorance may function as an emotion-regulation strategy, with age being a key factor.
