Brainstorming has some limitations and challenges that are unique to the session itself. Due to the high number of people in a brainstorming session, participants are pressured to generate good ideas in a specific time frame. Participants may or may not present specific ideas that they might find to be bad or useless, which may miss out on the overall point of the brainstorming session. Another problem that might arise in a brainstorming session is the lack of individual thinking. The brainstorming session might become an echo chamber if there is no person to think contrary to the belief of the group. This can cause further issues, as ideas and solutions that are different from the group’s preferences will be shot down and denied.
