We report experiments on sender-receiver games with an incentive for senders to exaggerate. Subjects "overcommunicate"—messages are more informative of the true state than they should be, in equilibrium. Eyetracking shows that senders look at payoffs in a way that is consistent with a level-k model. A combination of sender messages and lookup patterns predicts the true state about twice as often as predicted by equilibrium. Using these measures to infer the state would enable receiver subjects to hypothetically earn 16–21 percent more than they actually do, an economic value of 60 percent of the maximum increment.

Rapid decisions about political candidates, made solely on the basis of candidate appearance, associate with real electoral outcomes. A prevailing interpretation is that these associations result from heuristic cognitive processing of cues from the face to yield a judgment about the candidate, processing that is shared by both voters and experimental participants. Here, we report findings suggesting that nonfacial aspects of a candidate's appearance are important cues for voter decision making. We asked participants to look at pairs of candidate images and decide (a) whom to vote for (SimVote), (b) who looks more physically threatening (Threat), and (c) who looks more competent to hold congressional office (Competence). When participants saw only the candidates' faces, there was no association between their decisions and electoral outcomes, except for Threat. Yet when participants saw the candidate images with the faces removed, there was a strong association between their decisions and voters' decisions, for all decision types. This suggests that the appearance‐related heuristics that some voters use to guide their decisions may include mental schemas for processing appearance cues other than those associated with facial features. Such schema‐based processing has implications for understanding the neurobiological system underlying thin‐slice decisions from appearance alone.

The past decade has witnessed a renaissance in scientific approaches to the study of morality. Once understood to be the domain of moral psychology, the newer approach to morality is largely interdisciplinary, driven in no small part by developments in behavioural economics and evolutionary biology, as well as advances in neuroscientific imaging capabilities, among other fields. To date, scientists studying moral cognition and behaviour have paid little attention to virtue theory, while virtue theorists have yet to acknowledge the new research results emerging from the new science of morality
