Okay, now for my attempt to actually answer the prompt:

Your supposed "taste" for alcoholic beverages is a lie.

Summary: I've never enjoyed the actual process of drinking alcohol in the way that I e.g. enjoy ice cream. (The effects on my mind are a different story, of course.)

So for a long time I thought that, hey, I just have weird taste buds. Other people really like beer/wine/etc., I don't. No biggie.

But then as time went by I saw all the data about how wine-tasting "experts" can't even agree on which is the best, the moment you start using scientific controls. And then I started asking people about the particulars of why they like alcohol. It turns out that when it comes any implications of "I like alcohol", I have the exact same characterstics as those who claim to like alcohol.

For example, there are people who insist that, yes, I must like alcohol, because, well, what about Drink X which has low alcohol content and is heavily loaded with flavoring I'd like anyway? And wine experts would tell me that, on taste alone, ice cream wins. And defenses of drinking one's favorite beverage always morph into "well, it helps to relax..."

So, I came to the conclusion that people have the very same taste for alcohol that I do, it's just that they need to cook up a rationlizations for getting high. Still trying to find counterevidence...

Your turn: convince me that you really, really like the taste of [alcoholic beverage that happens to also signal your social status].

Sorry to comment on this so late, but I was very interested in the topic and have been tied up working late all week where I'm not able to stream videos.

It would be cool if lots of people made videos like these, maybe giving them a common prefix (Fallacy Finding - The South Carolina Democratic Primary Debate - Part 1), so that a search could be done to find all videos of a similar nature. I think a little community could build up around the idea. I'd certainly be interested in making and/or watching them.

I became aware of the sunk-cost fallacy one day when I bought a giant diet coke that tasted funny.

My first impulse was to drink it because I had paid for it, and because it was huge, and because it seemed a shame to waste it. I think I was too far away from the fast food place to complain.

Then I realized that I wasn't particularly thirsty (I'd been interested in the taste and had eaten the food I wanted to drink it with), it had no nutritional value, and I didn't get it for the caffiene boost. There was absolutely no reason to drink it, so I didn't. And felt pretty proud of myself for noticing how stupid it would have been to have drunk it.
