Turns Out, Forgiving Someone Actually Makes You Happier a Year Later

Ever been told to forgive and forget? Turns out, that sage advice might actually be backed by science — and could seriously boost your well-being a full year later. Because, apparently, holding a grudge is just that exhausting.

A massive new study, spanning 22 countries and over 200,000 people, has dug into the long-term ripple effects of forgiveness. Researchers at Harvard's Human Flourishing Program didn't just ask about warm fuzzies; they tracked 56 different measures of well-being over a year.

The takeaway? Regularly letting things go wasn't just linked to better psychological health; it also nudged people towards more positive character traits and prosocial behaviors, like gratitude. Richard Cowden, the lead author, put it plainly: forgiveness helps build character and improves your life choices. So, essentially, it's a self-improvement hack disguised as letting someone off the hook.

The Global Forgiveness Report Card

Published in npj Mental Health Research, this study builds on previous work that mapped out where forgiveness is more common globally. They weren't asking about one-off acts of saintliness, but rather how often people made forgiveness a habit. And the results are, shall we say, complicated.

Some nations, like South Africa, reported high levels of forgiveness. Others, like Japan and Turkey, were a bit less inclined to turn the other cheek. And while more forgiveness generally meant better well-being a year later, the strength of that link varied. In South Africa, for instance, high national forgiveness had a weaker connection to individual well-being. Researchers speculate this might be due to bigger societal challenges like poverty and crime, which tend to overshadow personal peace.

Cowden also mused that in cultures where forgiveness is expected, its perceived benefits might actually lessen. Because nothing saps the joy out of a good deed like being told you have to do it.

Flexing Your Forgiveness Muscle

Cowden likens forgiveness to a muscle you can build. And like any good workout, it gets easier with practice. He pointed to a 2024 study where people used a self-guided forgiveness workbook in places as diverse as South Africa, Hong Kong, Colombia, Indonesia, and Ukraine.

The participants reported feeling more forgiving, less anxious, less depressed, and generally better off. Which, if you think about it, is a pretty solid return on investment for a workbook.

Imagine the public health implications if more people could simply resolve their hurts through forgiveness. It’s a simple concept with the potential for genuinely massive benefits. And who knows, maybe a little less grudge-holding is exactly what the world needs right now.
