Wilful ignorance is a documented human behaviour whereby people deliberately avoid information. Although much work has documented consumer attitudes toward farm animal welfare, few studies have questioned whether people even want to know how farm animals are raised. Using an internet survey of 1,000 subjects from the US state of Oklahoma, it is shown that around one-third admit to being wilfully ignorant regarding pork production. One-third also chose to look at a blank screen rather than a picture of how pregnant hogs are housed. Avoidance of guilt is shown to be a motivator for this behaviour.

After California voters decided in a state initiative to ban gestation crates and battery cages, some are asking whether other states will host similar initiatives and if they will pass. This study addresses this question by using voting data in California to predict how voters in other states would respond to a similar initiative. Results suggest that a number of states allow such initiatives and possess a demographic profile favorable to the initiative's passage. However, because these states host only a small portion of the livestock population, the impact of such initiatives on the well-being of farm animals is questionable.
