Right, right. Don't get me wrong, I'm not saying that all beer is the same! The specific thing under test was the assertion that some of the "shitty" beers are better than others -- the stuff you can get a 12 pack of for under $10. The thing that spawned the test was someone objecting to me picking up a pack of Coors because it was on sale, to which I asserted that all of the cheap stuff is indistinguishable from one another, and thus snobbery is not needed. Which ultimately lead to our science throw down.
It was a very narrowly scoped test.
