A current debate concerns the degree to which moral rea-soning is susceptible to bias from low-level perceptual cues.P ̈arnamets et al. (2015) reported that moral decisions couldbe biased by manipulating the timing of a prompt to respondvia measurement of eye gaze, but these results were critiquedby Newell and Le Pelley (2018) as a potential design artifact.To reconcile these findings, we first replicate the previous ex-periments with an adjusted stimulus set. Then, we present theresults of a drift-diffusion model that simulates our findings,offering an account of the mechanism by which the gaze-basedtiming manipulation can bias moral decision-making.
