The Power of Regret: How Looking Backward Moves Us Forward: Summary & Key Insights

Before we can use regret, we need to understand what it truly is. Regret is the emotion we feel when we compare what actually happened with what could have happened if we had acted differently. Psychologists call this counterfactual thinking. Unlike disappointment, which arises when outcomes don’t meet expectations, regret is personal—it depends on the recognition that our own choices created the gap between the life we have and the life we might have had. It’s a self-conscious emotion, sitting at the intersection of agency and responsibility.

Neurologically, regret is powerful because it recruits both our emotional and cognitive systems. Brain imaging studies reveal that areas such as the orbitofrontal cortex light up when we experience regret, suggesting that our minds are actively simulating missed alternatives. This makes regret uniquely instructive—it’s not just about pain; it’s about learning. The mind prompts us to reflect, to ask, 'What went wrong?' and, more importantly, 'What can I do differently next time?'

Regret reminds us that we are meaning-seeking creatures. It’s our inner signal that tells us our actions have strayed from our values. Denying regret, therefore, is like disabling an internal compass. When we push regret away, we numb our ability to improve, to grow, and to connect. By bringing it into focus, however uncomfortable, we gain access to one of the most potent forms of self-awareness available to us.

To understand regret not as an isolated emotion but as a global human phenomenon, I launched the World Regret Survey—a sweeping data project that collected stories from people in more than one hundred countries. Tens of thousands of individuals shared their deepest regrets, some written in a few words, others in heartfelt essays. What was astonishing wasn’t the diversity but the similarity. Beneath cultural, economic, and personal differences, people regretted the same things in strikingly similar ways.

These regrets clustered around recurring themes. People regretted failing to save, study, or build a stable foundation for their lives. Others regretted times they stayed silent when they should have spoken, or failed to act boldly when opportunity knocked. Many felt the sting of violating their own moral code, or lamented the relationships they allowed to fade into silence. This massive dataset revealed what psychologists have long suspected: our regrets are mirrors of our values. What haunts us most tells us what we hold most dear.

This realization shifted my understanding of regret entirely. Rather than viewing regret as a catalog of mistakes, I now see it as a window into human aspiration. Across humanity, regret isn’t a mark of weakness; it’s evidence of our striving nature. It’s how we trace the outline of the life we wish to live.
