behavior, a variety of traits and inner states can be accurately perceived. Additionally, from these thin slices of behavior, even future outcomes can be predicted with some accuracy. Certain clinical disorders such as Parkinson’s disease and facial paralysis disrupt nonverbal behavior and may impair

A meta-analysis was conducted on the accuracy of predictions of various objective outcomes in the areas of social and clinical psychology from short observations of expressive behavior (under 5 min). The overall effect size (/) for the accuracy of predictions for 38 different results was.39. Studies using longer periods of behavioral observation did not yield greater predictive accuracy; predictions based on observations under Vi min in length did not differ significantly from predic-tions based on 4- and 5-min observations. The type of behavioral channel (such as the face, speech, the body, tone of voice) on which the ratings were based was not related to the accuracy of predic-tions. Accuracy did not vary significantly between behaviors manipulated in a laboratory and more naturally occurring behavior. Last, effect sizes did not differ significantly for predictions in the areas of clinical psychology, social psychology, and the accuracy of detecting deception. The way in which people move, talk, and gesture—their fa-cial expressions, posture, and speech—all contribute to the for-mation of impressions about them. Many of the judgments we make about others in our everyday lives are based on cues from these expressive behaviors. Gordon Allport (1937) believed that

Researchers typically study group conflict from the vantage point of the group members who experience and contribute to the conflict. Accordingly, conflict is usually measured by obtaining self-reports from the group members themselves or through the coded observations of trained researchers (Weingart, 1997). As appropriate as this focus may be, we propose that other perspectives are also important to organizational outcomes. Consider that organizational groups are often surrounded by external constituents who sometimes observe interactions, including conflict, among members of groups to which they do not belong. In an increasingly interdependent and collaborative world, all sorts of external parties might attend a group meeting or otherwise get a glimpse of group interaction, ranging from a superior who intermittently sits in on group decisions, to clients or vendors who receive the output of the group, to Human Resource professionals who are documenting group decisions, to members of other groups who attend meetings to share relevant information. Aided by the widespread use of video and teleconference communication technologies, including the increasingly easy and unobtrusive means to record videoconferences for others to observe, group interactions are frequently subject to the scrutiny of outsiders. These external observations of group conflict can have material

profiles in this process. By examining users ’ decisions in an experimentally controlled social network, we show that users need only a “thin slice ” of profile information in order to form impressions of others online. Additionally, specific profile attributes are evaluated for their perceived utility

Intuitive processing is critical for effective social and interpersonal interactions. Previous work has found that people are able to form accurate impressions that predict certain ecologically valid outcomes from brief observations or “thin slices ” of behavior. This article discusses theoretical

in online behavior. The question is how long does it take web surfers to form trustworthiness and emotional beliefs about a website that will influence future behavior? Using the concept of thin slice judgment, we posit that short glimpses of websites are accurate predictors of a web surfers
