Here's a stat that shouldn't be possible: something like 80 to 90 percent of missed greens are missed short. Not long, short, almost every time. If golfers were just randomly bad at distance, the misses would go both ways. They don't.

This is the finale of the series, and it ties back to a bias a researcher named Tali Sharot has spent her career studying, the same one that makes us all terrible at estimating how long anything takes. Turns out it's costing you strokes on every single approach shot, and the fix is free.

You know the line, "man, if I'd just made a few more putts." I've said it, you've said it, we've all said it walking off 18. Turns out it's probably not true, and there's a stat that proves it.

I get into research from the guy who invented strokes-gained, and where amateur golfers actually lose shots compared to better players. It's not the putting green, and once you hear the split, you might rethink how you spend your practice time entirely.

Quick — what percentage of the UN is African nations? Whatever number you just guessed, I can tell you exactly how to make you guess higher or lower, and it has nothing to do with facts. Researchers proved it decades ago with a rigged wheel of fortune.

Turns out you're carrying around your own version of that wheel every time you play, and it's called your score. I get into the research on anchoring bias and why the number on your card might be the quietest saboteur in your whole round.
