As people begin to join into larger groups, the very size may become a problem itself. Before the year is too far underway, it is important to note that the size of the group in question in particular causes diffusion of responsibility. Sometimes in groups of three or more, individuals feel less motivation to achieve something or work towards an end, often relying on others to complete a task as they feel the same in turn. Groups also may allow things to occurs as a result of inaction, believing someone else will handle things. Sometimes members will shirk culpability for mistakes, perhaps like a poor grade, and attribute it to the group as a whole. So as the year passes, keep these phenomenon in mind as you may be able to prevent them.
