Self-Evaluation: Self-Enhancement and Self-Verification

4.7K
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).

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

Understanding Deception

266
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...

Area of Science:

  • Psychology
  • Forensic Psychology
  • Deception Detection

Background:

  • The devil's advocate interview protocol is designed to detect lies concerning opinions.
  • It involves eliciting reasons supporting an opinion and reasons opposing it.

Purpose of the Study:

  • To investigate if including a "same example statement" enhances the devil's advocate protocol's ability to differentiate truth-tellers from liars.
  • To assess the impact of a model statement on detecting deception in expressed opinions.

Main Methods:

  • 171 participants (truth-tellers and liars) provided opinions on societal issues.
  • Half of the participants viewed a "same example statement" before their interview.
  • Interviews assessed eloquence, passion, and predictability in responses to opinion and devil's advocate requests.

Main Results:

  • The devil's advocate protocol showed differences in eloquence and passion between truth-tellers and liars.
  • The "same example statement" condition significantly enhanced the protocol's effectiveness in detecting deception.
  • Hypotheses were supported regarding increased eloquence and passion in truth-tellers.

Conclusions:

  • The devil's advocate interview protocol is a viable method for detecting deception in opinions.
  • Incorporating a "same example statement" demonstrably improves the accuracy of this deception detection method.
  • Eloquence and passion are key indicators for distinguishing genuine opinions from fabricated ones.
