Emotions drive human behavior, yet society has historically discouraged emotional expression and awareness. Consequently, many individuals expend considerable energy avoiding their emotions rather than learning from them. Stanford University estimates that 95% of information the brain processes is emotionally based or influenced. A review of the literature from Harvard examines the role of emotions in decision making. The authors conclude that "emotions are, for better or worse, the dominant driver of most meaningful decisions in life."
Jonathan Haidt, a social psychologist and professor, examines whether people operate from reason or emotion in his book The Righteous Mind. Through multiple studies comprising tens of thousands of participants, he demonstrates that people not only operate primarily from emotion, but that the vast majority actively resist changing their positions even when definitively proven wrong. The evidence suggests that humans are fundamentally emotional beings, not purely logical ones.
The following are notable passages from his work:
Intuitions come first, strategic reasoning second. Our moral thinking is much more like a politician searching for votes than a scientist searching for truth. Morality binds and blinds. It binds us into ideological teams that fight each other as though the fate of the world depended on our side winning each battle. It blinds us to the fact that each team is composed of good people who have something important to say.
Anyone who values truth should stop worshipping reason.
Haidt further argues that collegiate debate courses do not cultivate truth-seeking but instead teach individuals to rationalize their emotional biases in a manner that persuades others. In essence, people become more skilled at supporting their pre-existing emotional positions with logical arguments rather than genuinely shifting perspectives based on logic alone.
According to Dr. Travis Bradberry, the author of Emotional Intelligence 2.0, only 36% of people can identify their emotions as they occur — a concerning statistic given the significance of emotions to human functioning.
In psychology, emotions are heavily emphasized as a critical factor in good psychological health. Much of therapeutic work is dedicated to helping individuals learn to coexist with their emotions rather than avoid them. Its purpose is to facilitate emotional processing rather than suppression, avoidance, or compartmentalization.
Unexpressed emotions will never die. They are buried alive and will come forth later in uglier ways.
Anyone who has experienced a disproportionate reaction to a relatively minor event — the proverbial final straw — understands this principle intuitively. Unprocessed emotions represent mounting pressure within a system that will eventually reach a breaking point. Healthy emotional processing is an indispensable component of sound psychological health, which brings the discussion to emotional intelligence.
Emotional intelligence (EQ) refers to the degree to which an individual understands their own emotions, motivations, and values; how effectively they manage and work through their emotions; and how well they perceive and respond to others' emotions and behaviors. Emotional intelligence forms the foundation of healthy emotional regulation. According to Bradberry, emotional intelligence comprises four distinct categories:
Your ability to accurately perceive your emotions and stay aware of them as they happen.
Your ability to use awareness of your emotions to stay flexible and positively direct your behavior.
Your ability to accurately pick up on emotions in other people and understand what is really going on.
Your ability to use awareness of your emotions and the others' emotions to manage interactions successfully.
The first two categories address the ability to understand and regulate one's own emotions, while the latter two concern the ability to recognize and respond to others' emotions. Emotional intelligence has tangible, real-world consequences. The following are notable findings from Bradberry's research:
Individuals with average IQs outperform those with the highest IQs 70% of the time. This discrepancy is attributed to emotional intelligence.
In a study comparing 33 workplace competencies, emotional intelligence was the strongest predictor of performance, explaining 58% of success across all job types. Emotional intelligence alone accounts for nearly 60% of workplace success, while the remaining 32 competencies combined account for approximately 40%.
90% of top job performers also score high in emotional intelligence. Conversely, only 20% of bottom performers demonstrate high emotional intelligence — suggesting that reaching top-tier professional performance without emotional intelligence is exceedingly rare.
Individuals with high emotional intelligence earn, on average, $29,000 more annually than those with low emotional intelligence. Each point increase on Bradberry's emotional intelligence scale corresponds to approximately $1,300 in additional annual salary. This finding holds across industries, levels, and regions worldwide. For reference, the average salary in the U.S. is approximately $60,000 according to the Bureau of Labor Statistics — underscoring the substantial financial impact of emotional intelligence.
No profession has been identified in which performance and compensation are not correlated with emotional intelligence.
The following are relevant perspectives on emotional intelligence from other prominent researchers in the field:
Emotional intelligence is a way of recognizing, understanding, and choosing how we think, feel, and act. It shapes our interactions with others and our understanding of ourselves. It defines how and what we learn; it allows us to set priorities; it determines the majority of our daily actions. Research suggests it is responsible for as much as 80 percent of the "success" in our lives.
In the last decade or so, science has discovered a tremendous amount about the role emotions play in our lives. Researchers have found that even more than IQ, your emotional awareness and abilities to handle feelings will determine your success and happiness in all walks of life, including family relationships.
Emotional intelligence influences success across all relationship domains — familial, social, and professional. Neglecting emotional intelligence development, or dismissing it as negligible or irrelevant, results in the deterioration of interpersonal relationships. When emotions — whether one's own or others' — are consistently ignored, relational quality inevitably suffers.
How can emotional intelligence be developed?
Bradberry proposes strategies for developing emotional intelligence within each category, which are outlined below with additional commentary.
These strategies provide a strong foundation for emotional intelligence development. However, the most transformative approach involves addressing underlying emotional patterns at their root — cultivating an inner state where reactive triggers diminish and equanimity becomes the baseline. Treating every experience as information, learning from setbacks without self-condemnation, and making intentional choices about personal growth leads to lasting change. The ultimate aim is to develop an internal stability that external circumstances cannot easily disrupt — a state in which peace is not contingent upon conditions but is cultivated from within.
