I would think so, too. I would also hazard a guess which you might be able to refute or verify that very few things that are tested blind and ARE truly different are caught 100% of the time by all participants. 100% in anything at all is remarkable.

Have their ever been any tests that you are aware of where the items under test are blatantly different? I'd be interested to see the scores of such a test. It might help in determining just how worthwhile blind testing is. As a silly example, has anyone with normal tastebuds incorrectly guessed "apple" while tasting an orange? Ever?
