Summary
The widespread belief that morality is declining is an illusion. Psychological biases in information exposure and memory create this perception, despite objective moral standards remaining stable over time.
Area of Science:
- Social Psychology
- Sociology
- Moral Psychology
Background:
- Anecdotal evidence and public perception suggest a decline in global morality.
- This belief has persisted for at least 70 years across numerous nations.
- Attributions for perceived moral decline include individual aging and generational shifts.
Purpose of the Study:
- To investigate the pervasive belief in declining global morality.
- To determine if the perception of moral decline is empirically supported or illusory.
- To identify the psychological mechanisms underlying the illusion of moral decline.
Main Methods:
- Analysis of archival and original data from over 12 million individuals across 60 nations.
- Comparative analysis of historical and contemporary reports on morality.
- Experimental studies manipulating information exposure and memory recall related to morality.
Main Results:
- The perception of moral decline is widespread, enduring, and unfounded.
- Objective measures show no decline in the morality of contemporaries over time.
- Psychological biases, including biased information exposure and memory, create the illusion of moral decline.
Conclusions:
- The belief in declining morality is a cognitive illusion, not a reflection of reality.
- Understanding this illusion is crucial for addressing resource misallocation and social support deficits.
- The illusion can be attenuated, eliminated, or reversed under specific conditions, such as focusing on known individuals or historical periods.

Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Unrealistic Optimism Bias

Unrealistic optimism bias is the tendency to overestimate the likelihood of positive outcomes. This cognitive bias makes individuals believe they are less likely to experience failures, setbacks, or risks and more likely to succeed than others. For example, people may assume they are less prone to health issues, accidents, or financial struggles than their peers, even when they share similar risk factors.One key component of this bias is the above-average effect, where individuals perceive...
