I very much enjoy eating meat. However, animal suffering concerns me. Pigs pass a variation of the mirror test.
But I don't see any incentive to become a vegetarian when my decision will not change aggregate animal suffering or even prevent a single pig from being born into an existence of pure suffering. Their existence is so bad it's almost like they're not even alive. In the documentary Food Inc, the farmers refer to "growing" chickens, never raising chickens.
Is there any logical inconsistency here? It seems oddly convenient to be able to accept animal suffering yet be able to completely ignore it.
Your decision may or may not noticeably impact demand for meat; however, in aggregate with others making the same decision, it certainly does. You could be one of the hundreds of people who doesn't change anything; or you could be the one person on the tipping point whose decision prevents a new factory farm from opening, or shuts one down. The expected utility works out to saving or preventing the birth of as many animals as you don't eat.
I have noticed that among philosophers, vegetarianism of one form or another is quite common. In fact, I became a vegetarian (technically a pescetarian) myself partly out of respect for an undergraduate philosophy professor. I am interested in finding out if there is a similar disproportion in the Less Wrong community.
I didn't request that this go into Yvain's survey because I want more information than just what animal products you do or don't eat; I'd also like to see nuances of the reasons behind your diet. There are a lot more shades than carnivore/vegetarian/vegan - if you want to be a vegetarian but are allergic to soy and gluten, that's a compelling reason to diversify protein sources, for instance. I'd also like to hear about if you avoid any plant foods (if you think they're farmed in a way that's environmentally destructive or that hurts people or if you have warm fuzzy feelings for plants, maybe). Here are some questions that come to mind:
