Dr. Dean, who holds a PhD from University College London, emphasizes that happiness isn't solely dependent on external circumstances. Studies published on PsyBlog reveal that how individuals relate to others plays a crucial role in determining well-being levels. ## Research Methodology Over 18 years, the study involved surveys and behavioral experiments with more than 10,000 participants. Psychological tests proved strong correlations between specific personality traits and happiness. The research concluded that 50% of happiness is genetic, 10% depends on life circumstances, and 40% relates to intentional activities. ## Two Prominent Traits The research identified two personality characteristics with direct links to happiness: extraversion and emotional stability. Extroverts were found to derive more pleasure from social interactions. Emotionally stable individuals manage stress factors better, maintaining long-term happiness levels. ## Other Determining Factors The study showed conscientiousness, agreeableness, and openness to experience also contribute to happiness. Conscientious individuals achieve goals more successfully. Agreeable people form higher-quality social relationships, while those open to new experiences derive greater life satisfaction. ## Neuroscientific Evidence MRI scans revealed distinct activity patterns in the prefrontal cortex and amygdala of happy individuals. Those with high emotional stability showed lower cortisol levels. Extroverts displayed more active dopamine receptors in the brain's reward system. ## Practical Applications Based on findings, daily practices are recommended: strengthening social bonds, keeping gratitude journals, and embracing new experiences. Participants in a 6-week program showed 27% increased happiness levels. These techniques prove particularly effective for developing emotional stability. ## Long-Term Effects Individuals with high happiness levels demonstrated 31% better work performance and 43% higher relationship satisfaction. They showed 23% lower rates of chronic diseases and lived 7-10 years longer on average. This data proves happiness isn't merely a subjective feeling. ## Personal Development Insights The research emphasizes happiness as an improvable skill, recommending exercises to strengthen specific traits. For example, attending 3 social events weekly boosts extraversion, while meditation enhances emotional stability. These findings show individuals can actively shape their well-being. ## Sources covering this story - https://www.spring.org.uk/2026/07/5-happiness-traits.php — --- _Summary written by Brifing from the original reporting.
