Social scientists are increasingly interested in beliefs about farm animal well-being and the factors that predict these beliefs. Yet little attention has been given to the role of values, which social psychologists consider to be the building blocks of human cognition. This study draws from research on values in the environmental social sciences to examine the relationship between environmental values and Americans’ beliefs about farm animal well-being. It also makes a methodological contribution by demonstrating the importance of measuring beliefs about (...) farm animal well-being on large industrial and small family farms separately. A series of paired sample t-tests finds Americans believe the well-being of farm animals on large industrial farms is significantly worse than on small family farms. Multiple regression results reveal the importance of environmental values, as well as various demographic factors, in understanding beliefs about farm animal well-being. They also suggest the presence of direct and indirect effects of values on beliefs. Implications and avenues for further research are discussed. (shrink)
