Forgiving someone today might leave you feeling better a year from now, but don’t expect it to work the same way everywhere. A new Harvard study of 200,000 people across 22 nations says yes, but the effects are messy, uneven, and often tied to where you live. Human Flourishing Program researchers tracked forgiveness habits and well-being metrics over time, finding links to happiness, mental health, and pro-social behavior—but only sometimes. Richard Cowden, the lead scientist, called it “a pathway to building character,” but also admitted, “It’s not a magic bullet.”
Forgiveness as a Habit, Not a One-Time Act
The study didn’t ask, “Have you ever forgiven someone?” It asked, “How often do you forgive those who hurt you?” That’s a big difference. Cowden called it a measure of “dispositional forgivingness”—a habit, not a state. Think of it like exercise: you don’t do it once, you do it regularly. The data came from annual surveys, with follow-ups a year later. But here’s the kicker: the benefits varied. In some countries, forgiveness correlated with better mental health. In others, like South Africa, it didn’t quite pan out the way you’d expect.

South Africa has high national forgiveness rates, but the study found weaker links to well-being. Cowden guessed why: “Poverty, crime, trauma. Those things can drown out the psychological benefits.” It’s not just about forgiving—it’s about surviving. In Japan and Turkey, forgiveness levels were lower, but the cultural context might have made the practice less impactful. “You can’t separate forgiveness from the world around it,” Cowden said. “It’s not a universal fix.”
Forgiveness as a Muscle, Not a Virtue
Cowden compared forgiveness to a muscle you can build. He cited a 2024 study where people in South Africa, Colombia, and Ukraine used a self-help workbook based on the REACH forgiveness model. Participants reported less anxiety, depression, and more well-being. But here’s the thing: the study was small, and the real-world impact? Who knows. “We’re still figuring out what forgiveness even means,” Cowden admitted. “Until we know what the term really means, we can’t even begin to understand what’s happening.”
I’ve seen enough corporate spin to know that this isn’t just another feel-good study. The data is real, but the implications are messy. Forgiveness isn’t a panacea—it’s a tool, and it only works if the world around you lets it. In some places, it’s a luxury. In others, it’s a survival tactic. And in Japan? Maybe it’s just part of the culture. Who’s to say?
But here’s a cold fact: if everyone who’s ever been hurt could learn to forgive, the global health benefits might be staggering. Cowden won’t promise it. He’ll just say, “We’re still collecting data.”
