The Asymmetrical Contributions of Pleasure and Pain to Animal Welfare

Published online by Cambridge University Press:  04 February 2014

Abstract:

Recent results from the neurosciences demonstrate that pleasure and pain are not two symmetrical poles of a single scale of experience but in fact two different types of experiences altogether, with dramatically different contributions to well-being. These differences between pleasure and pain and the general finding that “the bad is stronger than the good” have important implications for our treatment of nonhuman animals. In particular, whereas animal experimentation that causes suffering might be justified if it leads to the prevention of more suffering, it can never by justified merely by leading to increased levels of happiness.

For many people, notably those privileged enough to be in academia, this depressing fact is neutralized by the fact that we have a much greater quantity of mildly pleasant experiences than we do negative experiences, and indeed the general “set point” for most people in normal situations is a mildly pleasant experience.
