Feynman highlights the practical value of direct discussion among people who understand a technical problem in detail. Engineers and other specialists can often contribute useful observations, alternative explanations or possible solutions because they share enough background knowledge to examine the issue closely.

The remark also points to the importance of open communication in technical organisations. Complex problems are less likely to be understood fully when information is isolated or filtered through layers of management. Discussion among knowledgeable peers allows assumptions to be challenged and uncertainties to be exposed before decisions are made. In the context of Feynman’s work on the Challenger investigation, this reflects his interest in hearing directly from engineers and specialists familiar with the Shuttle’s systems. More broadly, the quotation supports collaborative problem-solving in which technical expertise is exchanged freely and practical suggestions can be tested on their merits.
