Cognitive Fixation: the idea killer that lets you get stuck on the ideas of others
Just came across an article on the Washington Post’ Social Reader entitled “Why brainstorming doesn’t work”. I think most of us had the experience of failed or lackluster brainstorm sessions. In agency cultures, usually team-spirit and teamwork are often sought-for and proclaimed character traits that foster believe in a shared process of coming up with ideas. Territorial posturing aside, there are also some other issues at hand, that make brainstorming ineffective, as discovered by a recent study.
But according to a recently published study, the real problem may be that participants’ get stuck on each others’ ideas. Researchers asked undergraduate students to contribute ideas for improving Texas A&M, both individually and in collective groups. They shared the ideas on a computer, either in small chat groups or alone, but combined together after the fact. As expected, the “nominal” groups, or those made up of individual ideas that were later pulled together, outperformed the real chat groups, both with the number of ideas and the diversity of them.
The cause might be due to “cognitive fixation,” or the concept that, when exposed to group members’ ideas, people focused on those and blocked other types of ideas from taking hold. They experimented with this by manipulating the number of ideas participants saw in their chat windows, with some getting a few cues and others getting more. Their hypothesis was right: When exposed to many cues, the undergrads offered up less creative, diverse ideas. The numbers improved when the students were given a five-minute break during the exercise.
I am not sure the topic needed a study, because the insight is pretty common sense. However it reminds one to question the behavior to just pile a bunch of people in a room to create ideas.
