When working in a team, it is not necessary for the discerners to have better ideas than the inventors. The key is to tap into the geniuses of each team member and create a framework where everyone feels comfortable sharing their ideas. In this way, even if someone doesn't have a better idea, they can still provide valuable input by discerning and questioning the ideas put forward by others. By tapping into the collective strengths of the team, the innovation process becomes more robust and effective.
