Sebastian is helping his client solve a highly complex problem. He reached out to his professional network to solicit new and different ideas. Since his network consists primarily of people who are much like him (e.g., race, age, gender, education, etc.) he received suggestions that were all similar to each other, and similar to what he had already thought of. What is the most likely reason this happened? Because his network is insular, and that limits access to diversity of perspectives and thought Because people do not want someone else to take credit for their ideas Because the people he reached out to were busy and did not take time to think about the problem Because he had already thought of all possible solutions
