I could understand wanting to pull the pin if it wasn't straight in, but not otherwise. To me it makes sense that you would want the stick in the hole to use as a backboard if the ball approached the hole too fast. However, I didn't question the widely-held pin-pulling practice since golfers much more accomplished than myself believed in it.Thankfully, Dave Pelz, the mad scientist of golf, researched the effects of the flagstick on balls approaching the hole. He finally set the record straight, "Leave the flagstick in whenever the Rules allow, unless it is leaning so far toward you that the ball can't fit." I can finally sleep at night and write a golf blog without worry.

Yep. Ever since I read that study, what, ten years ago? Twelve? I have left the flagstick in when chipping or putting from off the green. It helps with distance perception as well, I think.
Tom, I don't know whether the speed of the ball matters, which is what Pelz impies. From a physics standpoint, the flagstick should not prevent a ball from going into the hole that would have gone in without the flagstick.
I guess I should step in here.
Assuming standard ball (diameter=1.68in) and hole (diameter=4.25in) sizes, I estimate that the max speed the ball could be traveling in order to go in the hole is around 5.4 ft/sec without the pin.
With the pin in the question gets a lot harder. At that max speed I would guess that the ball would deflect off the pin and miss the hole if it hit the flag straight on. So yeah, given perfect accuracy, there's probably some speed where the ball would go in without the pin, but not with it.
The difference though is that you won't lip out of the hole if you're slightly off center. You can hit the side of the hole with the flag in and still make it, whereas the ball would pop out without it. Given that, I tend to leave the pin in to prevent being robbed, and also because I'm usually too lazy to walk over and pull it.
Since the flagstick will absorb some of the energy of the ball at impact, the ball will always deflect off the flagstick with less speed. This is how the flagstick helps keep the ball in the cup.
Whenever I'm off the green with a putter in my hand I usually take it out, but if I'm chipping then I leave it in to take advantage of the flag stick stopping a chip too hard.
Dave's right about whenever the rules allow, but always take it out and put it waaay aside when your ball rests on the green. If your ball hits the flagstick during a putt, even if the flag is on the ground, it's a penalty.
It depends on if I know I can stop it or not. If I feel like I can hole the shot from off the putting surface I'm pulling the pin. However, if the shot is running away or I have a bad lie, I'm going to leave the stick in.
Golf Magazine did a study of 30,000 chips and putts from off the green. Their study showed you have a 50% better chance with the pin in than out. Here's the proof. Why do the rules say you have to take it out when you are on the green? Obviously it's considered an advantage.
From personal experience I have seen more balls prevented from going in the hole by a flagstick than I have ones that would have been stopped and dropped by the stick
I think an important issue is the lean of the flag. Many times a pin is leaning one way or another, and I'm pretty sure it's against the Rules to adjust it before a shot (though I would love clarification of that). If it's leaning toward you, and there's not enough room for the ball to drop straight in, I tend to remove it. If it's straight or leaning away, I'll leave it in. I've had perfect chips deflect away when it's leaning toward me. But it depends on the slope of the green too. If it's bending left or right, a forward leaning pin might give you the room on the side or back to let the ball in. That's what i love about the game, so many variables to crunch in a short amount of time and trying to make the smartest decision... which is also one of the reasons I sometimes hate the game! : )
No serious golfer should disagree with Pelz conclusions for what to do with the flagstick unless they have scientific data to back it up. Some of the commenter’s have missed the point that statistical data wins the arguments over memories of great chipping moments, or how a person “feels,” regarding the potential outcome of pulling or leaving in the flagstick. The only person here, who had anything close to a valid argument and who disagreed with Pelz conclusions, was Tom G. He was wise enough to insist on more specific data but was willing to bet against existing data that should apply, even to golfer of his incredible skill level. Of course Tom may be a little full of himself. I love it when people think that they are above solid research conclusions. Isn’t that just golf faith? I have not done a statistical study on faith but maybe Tom should accept that he is good at hole-outs due to his confidence with the pin out, in spite of the statistical data from Pelz. The point is that he is confusing confidence with science. Imagine if he could take advantage of both. But if he still wants to bet against a potential statistical data void by always pulling the flag, then I feel he will go to golf heaven 6.3 percent of the time—and I am willing to bet on that.
On windy days I want the pin out if Im chipping because we've had enough cases of a ball going into the hole only to be pinched back out because of the wind blowing the flag.
Science over percecption is what we are talking about here. Pelz did the test and it was conclusive. Leaving the pin in gives you not only the best chance to make the shot if you hit it perfect but also if you hit it too hard. The problem with the disbelievers is they think that the shots that are actually hit too hard would have gone in if the pin was out when in it would have skimmed over the hole to several feet past. I personally love it when my opponents take the flag out because their shot just got harder no matter how much it might boost their confidence.
It's interesting to hear that golf has these unspoken, long-standing rules!
I always leave the pin out when chipping, so many times over the years I have hit the pin which has stopped the ball from going in. I find with the pin out i tend to concentrate more and visualize the ball rolling into the hole. But that's just what works for me. I have a buddy who takes the pin out from 30 yards away, I think he has binoculars for eyes.
