実務上の急所は2つ。第一に、対人的な好意では有能さより温かさが優先される(primacy of warmth)——人を引き寄せる第一関門は「この人は信頼できる/敵ではない」という温かさの知覚です。第二に、高有能×低温かさは「妬み」を生む混合ステレオタイプになる。有能さの誇示だけを積み上げると、尊敬ではなく妬み・冷たさの知覚を招きうるのです。近年は温かさの中でも「道徳性(誠実さ)」が好意を駆動するという精緻化もあります。
Study 1のリーダー標本は n=34 と小規模です。また2020年の概念的追試(Leadership Quarterly)は動画教材版では初回失敗し、n=274・課題適合を改善した版で追認されました。「訓練で身につく」方向は堅いものの、効果の大きさや教材形式への頑健性はまだ発展途上です。なお「プロトタイプ性への標準化ベータ=0.84」という具体数値の主張は検証で棄却したため本レポートでは扱いません。
