Chapter 13 covers the topic of social psychology, or how people affect the actions of others. What I found most interesting was that recent studies show that brainstorming in a group setting is much less effective than brainstorming alone. We often keep some ideas to ourselves, because we are afraid of how others will perceive them. When in groups, we also tend to sit back and let others contribute, also known as 'slacking.'
So next time you are assigned to brainstorm in groups, show no fear! Take the lead and be one of the first to give your input. Do not be afraid about what other people will think of them; by not sharing, you are doing nothing but hurting your group. Like Michael Jordan once said, "you miss 100% of the shots you don't take."
