Patrick,
Your comments about Pumpkin Ridge do not offend me at all. I agree. Pumpkin Ridge does not present a comprehensive test of skill. Long, steep uphill and downhill putts are rare, and uneven lies in the fairway are almost non-existent. On the other hand, ambience, walkability, and course flow are excellent. It's a Doak 6, and a marginal top 100 candidate.
I'm sure there are many (dozens?) eastern parkland courses which offer a more comprehensive test, but I'm not a fan of the homogenous look. Pumpkin is carved out of an existing mature deciduous and evergreen forest, with generally wider corridors than usually found in Golden Age courses, and is a more attractive park.
There are several noteworthy examples of GCA members touting hometown courses, but after an initial response, I'm inclined to believe the correlation is weak. The Repeat Play bias is much stronger. The Remoteness Bias, as suggested by Tom Huckaby, makes sense to me. It feels special to travel so far from home. Perhaps there's a psychological need to justify the effort. But if Sand Hills and Ballyneal were down the street, I'd still try and belong to both!
I'd call Mike Sweeney's bias for sand-based courses a simple fact that they are better. I'll have to try and add Ballyneal to your list of favorites someday.
Similarly, Carl Nichols' mention of conditioning bias is not really a bias. Good conditioning yields better golf. What constitutes good conditioning is a matter of debate. A second potential bias, Amenities Bias, where the club rolls out the red carpet, is a tough one. I would propose that some course evaluators are swayed by the red carpet treatmanet, but there is no clearcut evidence to that effect. Furthermore, around here that sort is strongly discouraged.
Peter Pallotta brings up the concept of experience. My take on Experience Bias would be different. And just for you, I'll break out the popular music analogy. The older I get, the harder it is to impress me with a new song, because I've heard so many good ones in the past. The same applies to movies and golf courses. I've seen some great stuff, so it's harder to impress me when I get older. But when I do find something new and special, it's a gift.
"So as one sees more variety, does one become more "biased" because of likes and dislikes or less biased?" Mike Policano
I am more biased, because of more pleasant past experiences.
George Pazin mentions Player Bias. Some courses just don't set up well for certain types of players. I'm not a real accurate driver, and narrow, tree-lined parkland courses don't set up well for me. And you know what? I don't like them all that much, and tend to rate them accordingly. Am I showing personal bias against them? Sure. If you think hitting laser straight drives or punching out from the trees, and flopping sand wedges onto greens is great golf, bully for you. I don't. It can be great, but I like wide open, short grass, recover from anywhere golf better. If George doesn't like a course because he can't play it, then there's something wrong with the course, not George.
"What I meant was something more along the lines of the exchange between Rich Goodale and Tom Doak on Rich's recent "short par 4 made better when lengthened" thread. I think it's almost impossible for 99.9999999% of golfers to look past how he or she interfaces with a course, unless he simply walks it and studies other players." George Pazin
I agree completely. My goal is to play golf without prejudice. I hit golf shots. I don't care about ratings, or history, or old dead guy architects. None of that shit matters. I evaluate a course based on my experience hitting shots and watching my playing partners hit shots, and the enjoyment we derive from that activity. I don't think there's a bias, just our experience.
