The Big Five Model and How Personality Shifts with Age
Psychological research has long focused on the "Big Five" personality traits, a model that organizes human personality into five broad dimensions: Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness. While our core personality remains remarkably stable throughout life, longitudinal studies reveal predictable, average changes in these traits as we age, a process often termed "personality maturation". This article delves into which of the big five personality traits decreases with age and the reasons behind these shifts.
The Trait That Declines Most: Neuroticism
Of all the Big Five, Neuroticism shows the most consistent decline over the lifespan, especially from young adulthood through middle age. Neuroticism is characterized by a tendency toward negative emotions, anxiety, moodiness, and emotional instability. This age-related decrease is often associated with a significant improvement in emotional regulation and resilience. Older adults are generally better equipped to manage stress and let go of small frustrations, skills that are refined through years of life experience.
Life Experience Fuels Emotional Stability
The decline in neuroticism is not a sudden change but a gradual process. As individuals successfully navigate life's challenges, they build stronger coping mechanisms and gain a more balanced perspective. Studies show that this trend holds true until very late life, when a slight increase may occur, potentially linked to health declines or loss of loved ones. This maturation towards lower neuroticism is a key indicator of successful aging.
Extraversion's Changing Landscape in Later Life
Extraversion, which encompasses traits like sociability, assertiveness, and enthusiasm, also tends to decline with age, particularly after midlife. However, this trait is more complex. Research suggests that different facets of extraversion change at different rates. While aspects related to social dominance and confidence might increase in young adulthood, the social vitality aspect (sociability and activity level) tends to decline after the mid-50s.
Quality Over Quantity in Social Connections
Instead of seeking large social gatherings, older adults often prioritize deeper, more meaningful connections within a smaller social circle. This shift doesn't mean they are lonely or withdrawn; rather, it reflects a change in social priorities. A more relaxed and selective social life can contribute to greater overall life satisfaction.
Openness to Experience: The Quest for Familiarity
Openness to Experience, the trait associated with creativity, curiosity, and a willingness to try new things, also shows a gradual decline over the lifespan. This means that older adults may become more set in their ways and prefer familiarity over novelty. While this can sometimes be misconstrued as being rigid, it can also reflect wisdom and a clear understanding of one's preferences and what brings fulfillment.
The Nuances of Openness
It is important to note that a decline in openness does not necessarily equate to a negative outcome. Many older adults continue to engage in cognitively stimulating activities, and some studies suggest that maintaining openness can serve as a protective factor against cognitive decline. The key is a shift in motivation and focus rather than a complete cessation of new learning or creative pursuits.
Traits That Increase with Age: Agreeableness and Conscientiousness
While some traits decline, others increase with age, confirming the concept of personality maturation. Agreeableness and Conscientiousness both show a positive upward trajectory throughout adulthood.
- Agreeableness: The tendency to be warm, cooperative, and kind increases with age, peaking between the ages of 50 and 70. This trend is linked to greater emotional control and a focus on harmonious relationships, which contribute positively to interpersonal interactions.
- Conscientiousness: A reflection of self-discipline, organization, and a sense of duty, conscientiousness steadily increases through young and middle adulthood. This growth is vital for managing complex life roles and is associated with better life outcomes, including improved health and longevity.
Understanding the 'Why' Behind Personality Shifts
The changes observed in personality are not arbitrary; they are driven by a mix of biological, psychological, and social factors:
- Maturation Principle: Life experiences, social roles (like parenting and professional responsibilities), and personal growth lead to greater emotional stability and responsibility.
- Biological Factors: Age-related changes in brain structure and function can influence behavior and mood regulation. Hormonal shifts can also play a role.
- Environmental Influences: Major life events such as retirement, widowhood, or health issues can profoundly affect personality. Shifting social networks and roles also shape how individuals express their traits.
- Selective Optimization with Compensation: According to some theories, older adults focus on maximizing gains and minimizing losses by selecting key priorities, optimizing their abilities in those areas, and compensating for lost skills. This might explain the shift away from broad social activities towards a more focused, selective social life.
Comparing Personality Changes with Age
| Trait | Typical Change with Age | Rationale | Implications for Healthy Aging |
|---|---|---|---|
| Neuroticism | Decreases significantly | Improved emotional regulation, wisdom from experience | Increased emotional stability, better coping skills |
| Extraversion | Decreases, especially social vitality | Shift towards deeper, more selective social connections | Focus on meaningful relationships, potentially less social activity |
| Openness | Decreases, particularly after midlife | Preference for familiarity, established wisdom | Deeper engagement in existing interests, less exploration of new ones |
| Agreeableness | Increases steadily | Greater emphasis on harmonious relationships, emotional control | Enhanced social relations, more cooperative behavior |
| Conscientiousness | Increases through middle age | Improved self-discipline and responsibility | Better health, greater sense of purpose, structured routine |
What This Means for Healthy Aging
Understanding these age-related personality shifts can be a powerful tool for promoting healthy aging. Recognizing that a decrease in extraversion or openness is a natural part of maturing can help individuals and their families reframe these changes positively. Focusing on the positive increases in agreeableness and conscientiousness can highlight the strengths that come with age. While individual changes are not universal, these general trends provide a roadmap for understanding the psychological journey of late adulthood. By engaging in new activities that still align with a person's core values, seeking social engagement within a comfortable setting, and focusing on emotional well-being, older adults can navigate these changes with purpose and grace.

Conclusion
In summary, the Big Five personality traits most likely to decrease with age are neuroticism, extraversion, and openness to experience. These declines are not signs of a less functional person but rather reflect a natural process of maturation, where negative emotions mellow, social focus narrows, and stability is preferred. This shift often coincides with positive changes, such as becoming more agreeable and conscientious. Embracing these transformations can lead to a more peaceful, stable, and satisfying later life, underscoring the dynamic nature of personality throughout our years.
