# Independent Writing Minimizes Groupthink

When provoking an early exchange of ideas among executives, asking people to **write down their initial reactions independently** yields better information and minimizes groupthink compared to having them vocalize their thoughts in a group setting. This is operationalized in [[action-write-initial-reactions|the 'require independent written reactions' practice]] and is Step 2 of [[framework-reaching-true-agreement|the five-step process]].

**Enrichment / nuance:** Supported by a substantial body of decision-science research. **Brainwriting** and written idea generation often produce more diverse, higher-quality ideas than traditional brainstorming by reducing evaluation apprehension and conformity; studies on groupthink show that *prior independent judgment* reduces conformity and information-cascade effects (e.g., structured analytic techniques in intelligence analysis and juror decision-making). Caveat: effect sizes depend on context (group size, hierarchy, psychological safety), and how the written inputs are subsequently used matters.
