By the way, there is a name for the foible you described. It's called "Everyman's Syndrome".
And it seems as though golf not only brings a lot of that about, but it's brought on so often based on factoids (assumption or speculation that is reported so often that it becomes accepted as fact).
For years it was the adage "drive for show, putt for dough" that was given to everyone as though that was the biggest reason we don't score low. Then, someone collects a bunch of data refuting that belief and the next thing you know advice is being given to practice the full swing more than the short game - as though everyone has that exact same issue to fix. In my little world and with my game, both are equally poor.
This particular thread comes from a larger misbelief that every high or mid capper needs only to develop better strategy to experience better golf. I would gladly pay someone money and admit I was wrong if a different strategy or mental frame of mind would save me any more than a couple of strokes per round.
I think most agree that pulling a club based on the longest distance ever achieved with that club is not wise. Most of the responses indicate that is not what's happening. Yet, the message remains "pull more club".
