Another one that annoys me is the refrain that if someone plays poorly (or particularly well), or receives over-the-top service, or is met with challenging weather conditions that those non-golf-course variables affect rater scoring.
If you're so focused on your scorecard that it skews your view of the golf course you're playing, don't become a rater.
If you're so focused on how a club treats you and perhaps your ego needs massaging, don't become a rater.
If you're a fair-weather golfer who expects perfect conditions all the time, don't become a rater.
You know who you are and that's fine. You have different priorities, and we all play this game for widely differing reasons.
To my point earlier about raters voting in secret, in private, with no wish to offend ANY host or staff of any course, public or private, I would suggest that where Groupthink or at least self-censorship takes place is on social media, and here on GolfClubAtlas, where few would dare say that NGLA doesn't permit the running approach, even though it's modeled after holes in Great Britain where such shots are often accommodated, even preferred, or that Friar's Head's par fives are mostly scaled down versions of the same holes you'll find at Sand Hills, or that Cypress Point is not the greatest course in the United States even if it's the prettiest, or that Pine Valley's latest bunkering on 5 and 12 is atrocious looking and totally out of context with what Crump built.
Yet most are not afraid to publicly offer criticism of Pebble Beach, Bandon Dunes (all courses), Whistling Straits, and so on because those are still public, and your criticism doesn't come with the risk of losing access. It's human nature and understandable, but I'd argue the rankings are still the only place where individual subjective scores largely lead to objective consensus.
Yes, I know I'm an outlier, because I've made all of the above public criticisms of private shrines I listed above and have taken some private grief for those positions. But I still believe them all to be true.
I've also encouraged others to "show us your Doak Scale score" for new courses played each year and a few years recently spent a lot of time typing my own annual played-course list resplendent with my DS score and an attempted explanation, following the example of the "Confidential Guide", public or private. I believe those have more value to readers here than a lot of what we discuss.
So, I get the whole Groupthink vs Consensus argument, but I'd simply argue that Groupthink is much more prevalent in publicly viewable social media than anonymous print publication ratings.
