Physical cleansing has been a focal element in religious ceremonies for thousands of years. The prevalence of this practice suggests a psychological association between bodily purity and moral purity. In three studies, we explored what we call the "Macbeth effect"-that is, a threat to one's moral purity induces the need to cleanse oneself. This effect revealed itself through an increased mental accessibility of cleansing-related concepts, a greater desire for cleansing products, and a greater likelihood of taking antiseptic wipes. Furthermore, we showed that physical cleansing alleviates the upsetting consequences of unethical behavior and reduces threats to one's moral self-image. Daily hygiene routines such as washing hands, as simple and benign as they might seem, can deliver a powerful antidote to threatened morality, enabling people to truly wash away their sins.

Although power is often conceptualized as the capacity to influence others, the current research explores whether power psychologically protects people from influence. In contrast to classic social psychological research demonstrating the strength of the situation in directing attitudes, expressions, and intentions, 5 experiments (using experiential primes, semantic primes, and role manipulations of power) demonstrate that the powerful (a) generate creative ideas that are less influenced by salient examples, (b) express attitudes that conform less to the expressed opinions of others, (c) are more influenced by their own social value orientation relative to the reputation of a negotiating opponent, and (d) perceive greater choice in making counterattitudinal statements. This last experiment illustrates that power is not always psychologically liberating; it can create internal conflict, arousing dissonance, and thereby lead to attitude change. Across the experiments, high-power participants were immune to the typical press of situations, with intrapsychic processes having greater sway than situational or interpersonal ones on their creative and attitudinal expressions.Keywords: power, influence, conformity, dissonance, creativityThe assertion that social and mental life is directed by the situation is almost a truism in social psychology. Situational cues, social norms, and the attitudes and behavior of others all provide guidance and boundaries for acceptable thought and behavior, pressing individuals in predictable directions. Indeed, the range of situational elements that have been found to influence individual psychology, from various subtle nonsocial cues (e.g., Dijksterhuis

Four experiments explored whether 2 uniquely human characteristics-counterfactual thinking (imagining alternatives to the past) and the fundamental drive to create meaning in life-are causally related. Rather than implying a random quality to life, the authors hypothesized and found that counterfactual thinking heightens the meaningfulness of key life experiences. Reflecting on alternative pathways to pivotal turning points even produced greater meaning than directly reflecting on the meaning of the event itself. Fate perceptions ("it was meant to be") and benefit-finding (recognition of positive consequences) were identified as independent causal links between counterfactual thinking and the construction of meaning. Through counterfactual reflection, the upsides to reality are identified, a belief in fate emerges, and ultimately more meaning is derived from important life events.

The impact of diversity on group functioning is multifaceted. Exploring the impact of having a newcomer join a group, the authors conducted a 2 (social similarity of newcomer to oldtimers; in-group or out-group) x 3 (opinion agreement: newcomer has no opinion ally, one opinion ally, or two opinion allies) interacting group experiment with four-person groups. Groups with out-group newcomers (i.e., diverse groups) reported less confidence in their performance and perceived their interactions as less effective, yet they performed better than groups with in-group newcomers (i.e., homogeneous groups). Moreover, performance gains were not due to newcomers bringing new ideas to the group discussion. Instead, the results demonstrate that the mere presence of socially distinct newcomers and the social concerns their presence stimulates among oldtimers motivates behavior that can convert affective pains into cognitive gains.
