I have often been asked whether doing something kind for someone and not having it reciprocated makes me naive, or used, or just not paying attention. I pause on that question every time. No. I have never thought an act of kindness was wasted. Being kind is not a choice I make situationally — it is a way of life. When I extend kindness, it comes from a place that feels right and good, regardless of what comes back. And as it turns out, the research on kindness and intelligence suggests there is something real behind that instinct.
According to a growing body of research, goodness is one of the greatest markers of intelligence. "The basis of a healthy brain is goodness." That framing resonates deeply.
Kindness and Intelligence: What the Research Actually Shows
Thinking Beyond Yourself
The connection between kindness and intelligence starts with perspective-taking — the ability to step outside your own experience and genuinely consider someone else's. Intelligence is commonly defined as "the ability to acquire and apply knowledge and skills." Under that definition, emotional and social insight count. Applying what you know about human experience to the way you treat people is a form of sophisticated reasoning.
Thinking through someone else's lens takes insight and intuition that self-focused thinking doesn't require. Kind people regularly make personal sacrifices — of time, money, energy — because they are capable of reasoning that doing so makes the broader world better, not just their own small corner of it. That is not naivety. That is a particular kind of cognitive sophistication.
What Studies Show About Mean People
Research has consistently found a relationship between lower cognitive flexibility and a tendency toward prejudice and exclusion. A Canadian study referenced in LiveScience found that people who held more racist and prejudiced views tended to score lower on IQ measures than those who were more accepting of others. The study was originally designed to explore political ideology but revealed this pattern in its findings.
The explanation that resonates most with researchers is adaptability. People who resist change — who struggle to update their worldview in response to new information or new people — are demonstrating a form of cognitive rigidity that correlates with lower intelligence across multiple measures. As many researchers have noted, the ability to accept change requires self-examination, the willingness to let go of prior beliefs, and the capacity to sit with uncertainty. These are not small things.
Adaptability as a Marker of Intelligence
Fear of change is part of being human. Nobody is exempt from it. But the capacity to move through that fear, to question your own perspective and allow it to shift, is what separates a flexible, growing mind from a stagnant one. Kindness toward people who are different from you — who come from different backgrounds, hold different beliefs, live different lives — requires exactly this kind of adaptability. It requires seeing your worldview as one among many rather than the only valid one.
Wayne Teasdale put it plainly: "Kindness is the highest form of intelligence." The kindness and intelligence connection, seen through this lens, becomes almost obvious.
Emotional Intelligence and Why It Matters
The Limits of IQ
High IQ scores do not automatically produce wise, generous, or effective people. Research on kindness and intelligence acknowledges that people with very high IQs sometimes trend toward arrogance and a diminished capacity to recognize their own blind spots. IQ tests measure a narrow slice of what it means to be intelligent. Most researchers now recognize at least three kinds of intelligence — cognitive, emotional, and social — and the latter two are the ones most closely tied to kindness.
Emotional intelligence is the ability to understand and respond to the feelings of others. It requires empathy, self-awareness, and the capacity to regulate your own emotional responses well enough to be genuinely present to another person. This is harder than it sounds and has nothing to do with education level. A person with a postgraduate degree who lacks empathy is not more intelligent in the ways that matter most to human connection.
What Denmark Got Right
Schools in Denmark have taught empathy alongside core curriculum subjects for decades. One hour each week is devoted to helping children develop compassion, understand the emotional experiences of others, and practice perspective-taking in structured ways. The reasoning is straightforward: empathy requires significantly more cognitive effort than memorizing facts. It is active, effortful, and developmental. Teaching it as a skill, rather than assuming it will emerge naturally, reflects a sophisticated understanding of what intelligence actually encompasses.
The kindness and intelligence link ultimately comes down to this: acting with genuine goodness toward others requires you to think carefully, feel accurately, and reason beyond your own immediate interests. That is not a soft skill. It is one of the most demanding cognitive tasks a person can undertake.
