Which technique guides a group in an interactive exchange of ideas, deferring judgment until the end of the session?

The technique that guides a group in an interactive exchange of ideas while deferring judgment until the end of the session is brainstorming. This approach encourages participants to share their thoughts freely without criticism or evaluation during the idea generation phase. The primary goal of brainstorming is to foster creativity and generate a wide range of ideas, allowing participants to think outside the box and build on each other's suggestions.

Once all ideas have been collected, the group can then assess and evaluate them, facilitating a more open and innovative environment for problem-solving. This method contrasts with other techniques, such as discussion or debate, where judgment and critique might occur earlier in the process. In brainstorming, the emphasis is on quantity and creativity of ideas, rather than immediate validation or critique.
