Some studies assume that the prediction of human values on consumer choices is mediated by the attitudes of the products, but do not test if they are moderators of this relation and suppressors of the previous choice. The moderation and suppression would be likely observing the quality and level of intensification or attenuation of the values on decisions and on the inertia of choices, assuming they are not causes of them. We performed interaction tests of values with the importance of decision criteria to predict preference for products and brands, considering the previous choice. Logistic and ordinal regressions reveal that human values moderate the decisions regarding preference and suppress the inertial influence of previous choice with good fit and predictive power. The results help to understand the role of human values on consumer choices.
