Summary
This study investigated negative social influence, where people shift opinions away from others. Findings reveal a positive linear relationship between opinion distance and opinion shifts, challenging existing theories.
Area of Science:
- Social Psychology
- Opinion Dynamics
Background:
- Classical theories and formal models emphasize negative social influence, defined as shifts away from others' opinions.
- Hypotheses suggest discrepancy or disliking of the opinion source triggers negative influence.
- Empirical support for positive social influence is strong, but evidence for negative influence is mixed.
Purpose of the Study:
- To examine the role of positive and negative social influence in opinion change.
- To test whether opinion discrepancy or source disliking elicits negative influence.
- To investigate the relationship between opinion distance and opinion shifts.
Main Methods:
- Two experiments were conducted: one with controlled exposure to others' opinions, and another involving opinion exchange.
- Participants' opinion shifts were measured in response to varying levels of similarity and dissimilarity with influence sources.
- Statistical analyses were used to assess the impact of discrepancy and disliking on influence.
Main Results:
- Similarities between individuals were found to induce attraction, supporting positive influence.
- Evidence did not support that discrepancy or disliking triggers negative social influence.
- A consistent positive linear relationship was observed between the distance of opinions and the magnitude of opinion shifts.
Conclusions:
- The findings challenge established theories positing negative influence from discrepancy or disliking.
- A robust positive linear relationship between opinion distance and opinion shifts is suggested.
- Future research should explore alternative mechanisms driving opinion change beyond negative influence.

01:29Self-Discrepancy and Its Effects
410
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

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...

The similarity-dissimilarity effect, a fundamental concept in social psychology, explains how interpersonal similarities and differences influence attraction and social interactions. This effect is supported by three key psychological perspectives: balance theory, social comparison theory, and consensual validation.Balance Theory and Cognitive ConsistencyBalance theory, developed by Fritz Heider, posits that individuals seek cognitive consistency in their relationships. When two people share...

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?

Work is done on an object when energy is transferred to the object. In other words, work is done when a force acts on a body that undergoes a displacement from one position to another. By definition, the work done by a force is the integral of the force with respect to the displacement along its path. Forces can vary as a function of position, and displacements can occur along various paths between two points. The magnitude of a force multiplied by the cosine of the angle that the force makes...
