We tend to see what we want to see
Common parlance such as “ray of hope” depicts an association between hope and the perception of brightness. Building on research in embodied cognition and conceptual metaphor, we examined whether incidental emotion of hopelessness can affect brightness perception, which may influence people’s preference for lighting. Across four studies, we found that people who feel hopeless judge the environment to be darker (Study 1). As a consequence, hopeless people expressed a greater desire for ambient brightness and higher wattage light bulbs (Studies 2 and 3). Study 4 showed the reversal of the effect — being in a dimmer (vs. brighter) room induces greater hopelessness toward the perceived job search prospects. Taken together, these results suggest that hopeless feeling seems to bias people’s perceptual judgment of ambient brightness, which may potentially impact their electricity consumption.
