I don't understand why this post and some of Dmytry's comments are downvoted so hard. The idea might be far-fetched, but certainly not crazy, self-contradictory or obviously false.

My personal impression has been that emotions are a result of a hidden subconscious logical chain, and can be affected by consciously following this chain, thus reducing this apparent complexity to something simple. The experiences of others here seem to agree, from Eliezer's admission that he has developed a knack for "switching off arbitrary minor emotions" to Alicorn's "polyhacking".

It is not such a big leap to suggest that our snap moral judgments likewise result from a complex, or at least hidden, subconscious reasoning.
