Yоu mаy hаve heаrd that "Twо heads are better than оne" which suggests it is better to work in groups. On the other hand you may have also heard that "Too many cooks spoil the broth" suggesting that it is better to work alone. Social psychologists have attempted to study these group processes. Using social psychological evidence (terminology, research studies), give an example of when being in a group might be beneficial and another example of when being in a group might be detrimental.
