Technology has become all-important in modern society. For each application, it is crucial for society to have a good understanding of the risks and benefits involved. However, experts tend to assess the risks very differently than the public. One of the main reasons is that experts tend to rely on an objective analysis of the facts, whereas laypeople’s judgment is also based on other factors, including emotional responses. The question remains however whether that is a good thing. Some argue that emotions lead to biases and should be treated with great suspicion; others claim that the laypeople’s approach to risk is much richer and should also be taken into consideration. In this paper, I explore how we can answer that important question from an evolutionary perspective. First, I briefly outline the role of emotions in judgment and decision making. Next, I discuss two approaches that have defended the rationality of emotions: Roeser’s concept of emotions as trustworthy indicators of moral risks and Kahan’s cultural evaluator theory. Subsequently, I briefly discuss the evolution of emotions and their impact on risk assessment. I conclude from that account that emotions are not trustworthy guide for policy making
