The epilogue closes the book by shifting from individual strategies to a broader, data-driven view of how emotional intelligence plays out across workplaces and cultures. Drawing on TalentSmart’s Emotional Intelligence Appraisal® results from 500,000 people worldwide, Bradberry and Greaves use real-world patterns to reinforce their central claim: EQ is both a learned skill and a fragile one that can rise or fall depending on external pressures.

From 2003 to 2007, the proportion of US workers with high emotional intelligence rose from 13.7% to 18.3%, while those with poor awareness of emotions like anxiety and anger dropped from 31% to 14%. The authors attribute this progress partly to a “social contagion” effect, where working with emotionally skilled people helps raise others’ abilities. Yet the 2008 recession reversed the trend, with high-EQ individuals falling to 16.7%. This decline illustrates how stress can erode the very skills needed to manage it.

The authors also break down differences across gender, hierarchy, generation, and culture. Women initially outperformed men in most EQ skills, but men narrowed the gap in self-management over time. Middle managers scored highest overall, while CEOs scored lowest, highlighting the risk of emotional disconnect at the top. EQ levels tended to rise with age, and a 2005 study of 3,000 Chinese executives revealed higher self-management and relationship management scores than their US counterparts.

The multi-year data show that skill gains can accumulate across large populations when awareness and practice are sustained, yet they also reveal how quickly those gains can erode under collective stress, as seen during the 2008 recession. This makes the authors’ call for continuous practice a practical safeguard against regression. While the proprietary nature of the TalentSmart data limits independent verification, the breadth of the dataset lends weight to the trends described. The analysis implicitly challenges organizations to think of EQ not as a one-off training initiative but as an ongoing, measurable part of workforce development. In doing so, the Epilogue functions as both a closing argument for the book’s practical value and a cautionary reminder that the competitive and human benefits of EQ will only last if they are actively maintained.

Chapter Lessons

• Emotional intelligence can improve across large populations when people consistently apply and reinforce EQ skills in daily life.
• Stressful events, such as economic downturns, can erode even well-developed emotional skills, making ongoing practice essential.
• Differences in EQ across gender, leadership levels, and cultures suggest that both individual habits and systemic factors shape emotional competence.
• To ensure lasting gains, organizations should treat EQ as a continuous development priority rather than a one-time training effort.
