Summary
Introducing a novel cost of value-behavior inconsistency, this study shows it promotes cooperation in structured populations when regret costs are lower than guilt costs. This mechanism is robust across various conditions.
Area of Science:
- Evolutionary game theory
- Social dynamics
- Behavioral economics
Background:
- Cooperation evolution is studied across disciplines, but individual opinions are often overlooked.
- Existing models focus on population structure, neglecting the role of internal values.
- Cognitive dissonance theory suggests psychological costs for inconsistent behavior and opinions.
Purpose of the Study:
- To investigate the impact of value-behavior inconsistency costs on cooperation in structured populations.
- To determine the conditions under which psychological costs promote cooperative behavior.
- To analyze the co-evolution of opinions and behaviors in evolutionary dynamics.
Main Methods:
- Mathematical modeling of stochastic evolutionary dynamics on networks.
- Analysis in the weak selection limit for general network structures and multiple opinions.
- Validation on an empirical network and for non-weak selection intensities.
Main Results:
- Value-behavior inconsistency cost promotes cooperation if the cost of regret is less than the cost of guiltiness.
- Individuals exhibiting value-behavior consistency are more prevalent than inconsistent individuals.
- The findings hold across different population structures and selection strengths.
Conclusions:
- Value-behavior inconsistency is a robust mechanism promoting cooperation in structured populations.
- The co-evolution of opinion and behavior is crucial for understanding cooperation.
- This research opens new avenues for studying cooperation by incorporating psychological factors.

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

43
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.

01:21Behavior Modification
125
Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.

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...

01:28Behaviorism
2.2K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
