Social loafing is the effect that people will put in less effort if they work in a group environment. Group work is an integral part of everyday life as it occurs in almost every context whether sports teams, organizational groups, project groups and even juries. It is therefore important to understand the underlying factors that influence this construct. The current research, consisting of 20 participants, studied the social loafing effect of two working conditions: coactive and collective. It was hypothesized that collective groups would have significantly lower scores than coactive ones and the results strongly supported this prediction as there was a significant difference between groups. These results, however, strongly imply that collective work teams are generally more prone to social loafing; this could be minimized if certain factors such as interaction and task complexity were incorporated. The extent to which social loafing occurs among participants who complete a brainstorming task cooperatively or collectively. Social loafing is the effect of people exerting less effort when they work collectively than when they work collectively. they work cooperatively (Brickner et al., 1986). The social loafing effect can occur in many contexts and be reflected in tasks that require physical effort, cognitive effort, and alertness (Brickner et al., 1986). Létane (1979) suggested that social loafing is mediated by the equal distribution of effort and responsibilities within a group task performance context. Participants therefore had a mindset that they could “hide in the crowd” to avoid being blamed for slacking off or even “mixing in.” “joining the crowd” where they cannot claim their work credit.
