People Are Less Nice When in a Hurry <i>(But Mindfulness Might Help)</i>

ABSTRACT This research examines the impact of hurrying on niceness, understood as acting in a warm and friendly way in everyday social interactions. Building on classical research showing that hurrying has a negative effect on helping, we hypothesised that it would also diminish niceness. Across four studies ( N = 722), including two experiments where a sense of hurry was induced, we found both correlational and causal evidence that niceness was lower in a hurry than in no‐hurry. This effect was not present in individuals with high levels of mindfulness. These findings suggest that a fast‐paced lifestyle may undermine interpersonal niceness, while mindfulness skills may buffer against this effect.
