This isn't the first test I've seen that had similar results. Here's another one, done with regular people, not experts: http://scienceblogs.com/cognitivedaily/ ... els-als-1/
Then, of course, there's the humiliating (to the French, that is) "Judgement of Paris" wine tasting, in which a couple of blindfolded French wine judges chose California winners in every category, thinking every wine at the tasting was a French one.

All of this goes to prove that we let our biases override our senses. We do it with everything; a law change proposal by a popular Republican is viewed, and reacted to, differently than the same exact proposal by a popular Democrat. Identifying that we have these biases, and trying to account for them in our thinking and judgement, is the only thing that might give us a chance at really changing the world for the better, in my opinion. Unfortunately, the vast majority of us would rather just keep being heavily biased while thinking we aren't, and pretending we're even-keeled in everything we think.
If we have any resident wine snobs, (I say that almost lovingly, by the way; I drink wine more than any other form of alcohol) I'd be curious to read their thoughts.
