解説
問 3
Incorrectア
“Speaking up only about the ideas one considers high in quality” goes against the “quantity over quality” principle. Screening ideas by yourself before speaking reduces the total number of ideas and also loses the chance for a seemingly dull idea to spark further associations. Evaluating and narrowing down belong to a separate step carried out after the brainstorming session ends.
Incorrectイ
“Criticizing without any reservation” runs directly counter to the “no criticism” principle. Once criticism appears, participants become inhibited and find it hard to speak up, and free thinking comes to a halt. The rule is to leave judgments of good and bad to a later evaluation stage.
Incorrectウ
“Refraining from remarks that add improvements to ideas raised by others” goes against the “combination and improvement (piggybacking welcome)” principle. Piggybacking — combining or developing someone else's idea — is in fact actively encouraged, not something to hold back on.
- エ
正解 Brainstorming is an idea-generating method in which a small group freely exchanges opinions, first building up the number of ideas and only later organizing and evaluating them. Its basic rules are summed up in four principles: no criticism (do not reject an idea once it is raised), freewheeling (even outlandish ideas are welcome), quantity over quality (get the numbers out first), and combination and improvement (build on and develop other people's ideas). Choice エ, “Welcome free and unrestrained remarks, including outlandish ideas,” states the “freewheeling” principle directly, and it matches the aim of brainstorming: it is precisely the remarks that step outside the frame of common sense that become the seeds of new ideas. Therefore エ is the appropriate rule.
ここがポイント
- Memorize the four principles of brainstorming — no criticism / freewheeling / quantity over quality / combination and improvement (piggybacking welcome) — and judge each choice by which principle it violates.
- The key point of an idea-generating method is to separate divergence (the stage of putting ideas out) from convergence (the stage of evaluating and selecting); any choice that brings evaluation into the divergence stage is wrong.
