Psychologists have long known that we don't remember experiences the way we think we do. Rather than judging an event by everything that happened, our minds tend to remember two things most vividly: the emotional peak and the way an experience ends. It's known as the Peak-End Rule, a concept introduced by Daniel Kahneman.
Golf may be one of the clearest examples.
On Sunday at the John Deere Classic, Ben Kohles stood on the 72nd hole with a chance to earn his first PGA Tour victory. After finding the fairway, his approach found the water, and within a matter of minutes, a remarkable week ended in heartbreak. It was a difficult finish, but what struck me most wasn't the shot itself — it was how quickly that one moment became the story everyone remembered.
The truth is, Kohles didn't put himself in contention because of one swing. He played seventy-one outstanding holes to reach that position. He handled pressure, bounced back from mistakes, and gave himself an opportunity that thousands of professional golfers spend their careers chasing. None of that disappeared because one iron shot drifted left. Yet for many people watching, the final hole became the entire tournament.
Amateur golfers do this every weekend.
We hit twelve good drives, make a handful of solid putts, and finally feel as though our game is coming together. Then we finish with a double bogey, a three-putt, or one careless swing into the trees. During the drive home, we replay that single mistake over and over until it overshadows everything else we did well.
The scorecard doesn't make that mistake. It records every shot equally.
Our minds don't.
That's the danger of the Peak-End Rule. It quietly convinces us that the final chapter is the entire story. A round filled with progress suddenly feels like a failure because of the way it ended.
What impressed me most about Kohles was his perspective afterward. He spoke about being proud of the way he played, about learning from the experience, and about using it as motivation for the next opportunity rather than letting one hole define him.
That's a mindset every golfer would benefit from adopting.
The next time you finish a round, resist the urge to judge four hours of golf by the final five minutes. Remember the par save on the seventh, the drive you committed to under pressure, or the iron shot you flushed into the toughest green on the course. Those swings count just as much as the last one.
One swing can change a tournament.
It should never become the entire story of your round.
Today's Lesson
Your mind naturally remembers how a round ends. Don't let one bad swing erase the dozens of good ones that got you there.
