The Surprising Link Between Kindness and Intelligence

Inspired by insights from organizational psychologist Adam Grant as highlighted in an article by INC.

When we think of intelligence, we often imagine high test scores, problem-solving abilities, or an exceptional memory. But science suggests that intelligence goes far beyond academics. According to research shared by organizational psychologist Adam Grant, one of the strongest indicators of intelligence isn’t IQ or technical skills—it’s kindness.

This challenges the traditional view of intelligence and reinforces the case for Social and Emotional Learning (SEL) in schools. If we want to raise truly intelligent students—ones who excel not just in academics but in life—we need to prioritize SEL. Because intelligence isn’t just about what we know; it’s about how we understand, interact with, and support others.

What the Research Says

The idea that kindness is linked to intelligence is backed by multiple studies. Research referenced in INC. highlights that individuals who exhibit generosity, empathy, and thoughtfulness tend to have higher levels of cognitive complexity and emotional intelligence.

Grant, along with other psychologists, has found that highly intelligent individuals are often more cooperative, better at understanding different perspectives, and more willing to help others succeed. This is because intelligence isn’t just about processing information—it’s about applying it in ways that benefit the greater good.

And what does that sound like? SEL.

SEL is built on the principles of self-awareness, social awareness, and relationship skills, all of which reinforce the behaviors associated with high intelligence. By fostering kindness and emotional intelligence, SEL prepares students to succeed in school, the workplace, and society.

Why Kindness and SEL Go Hand in Hand

So why exactly is kindness a sign of intelligence, and how does SEL cultivate it?

1. Empathy Strengthens Critical Thinking

   • Understanding others requires deep cognitive engagement—students must consider different viewpoints, interpret emotions, and respond appropriately.

   • SEL teaches students how to listen actively, interpret non-verbal cues, and resolve conflicts—all essential to emotional intelligence and higher-order thinking.

2. Collaboration Enhances Problem-Solving

   • Highly intelligent individuals don’t work in isolation; they collaborate and build networks.

   • SEL fosters cooperation, helping students develop relationship-building skills that are essential for career success and leadership.

3. Regulated Emotions Improve Decision-Making

   • Impulsivity often leads to poor choices, while emotional regulation allows for strategic thinking.

   • Through SEL, students learn to manage emotions, practice patience, and think before reacting—skills that translate directly to academic and personal success.

4. Kindness Builds a Thriving Community

   • Studies show that kind people create environments where innovation and success flourish.

   • Schools that embrace SEL see reduced bullying, improved classroom behavior, and stronger peer relationships, creating a space where all students can excel.

Schools Must Prioritize SEL If They Want Intelligent Students

It’s time to redefine what intelligence looks like in education. If we want students to be truly smart—not just in math or science, but in life—we must teach them the skills that scientific research now recognizes as the most important indicators of intelligence.

When kindness is integrated into education through SEL, we’re not just producing good people; we’re producing highly capable, emotionally intelligent, and successful individuals. Schools that prioritize SEL will ultimately develop students who are not only academically strong but socially and emotionally equipped to thrive.

The future of intelligence isn’t just about knowledge. It’s about wisdom, connection, and the ability to navigate life with empathy and purpose. And that starts with SEL.

A Call to Action for Educators

If intelligence is about adaptability, cooperation, and emotional depth, then SEL should be at the core of every school’s curriculum. Schools that teach kindness aren’t just promoting good behavior—they’re shaping the next generation of highly intelligent leaders.
