内的統制型は結果を自分の行動に、外的統制型は運や他者に帰属します。内的統制は主体性や学習と関連しますが、極端になると統制不能な事柄まで自責する危険があります。An internal locus attributes outcomes to one's own actions; an external locus attributes them to luck or others. An internal locus is linked to proactivity and learning, but in the extreme it leads to self-blame for uncontrollable events.
Rotter は 1966 年に、人が自分の行動と結果の関係をどう一般的に期待するかを「統制の所在」として概念化し、測定尺度を開発しました。数十年の研究で、内的統制は学業成績、職務満足、健康行動、ストレスへの能動的対処と正の関連を示す一方、外的統制は無力感や受動性と関連することが繰り返し報告されています。ただし正解の選択肢が示すように、内的統制が極端になると、景気後退や病気など自分では変えられない事柄まで自己責任と捉え、不必要な自責や燃え尽きにつながります。健全なのは、Covey の影響の輪の考え方と同様に、統制可能なことと不可能なことを見分けたうえで前者に内的統制を適用する姿勢です。選択肢Bは性格特性との混同、Cは統制の所在が経験や訓練で変化するという知見と矛盾、Dは研究結果と逆です。文化差も報告されており、集団主義的文化では外的な要因の重視が必ずしも不適応を意味しないことにも注意が必要です。In 1966 Rotter conceptualized locus of control as a person's generalized expectancy about the relationship between their behavior and outcomes, and developed a scale to measure it. Decades of research have repeatedly linked an internal locus to academic achievement, job satisfaction, health behaviors, and active coping with stress, while an external locus is associated with helplessness and passivity. As the correct option notes, however, an extreme internal locus leads people to treat even uncontrollable events such as recessions or illness as personal responsibility, producing needless self-blame and burnout. The healthy stance, consistent with Covey's circle of influence, is to distinguish controllable from uncontrollable matters and apply an internal locus to the former. Option B confuses it with personality traits, option C contradicts findings that locus of control changes with experience and training, and option D reverses the evidence. Cultural differences also exist; in collectivist cultures, weighting external factors does not necessarily indicate maladjustment.
内的統制を礼賛する文化では、成功者が「自分の努力の結果だ」と信じ込み、運や環境の寄与を過小評価する傾向（Michael Sandel が『実力も運のうち』で批判した能力主義の傲慢）が生じます。逆に、不運な人に対して「あなたの心構えが悪い」という不当な非難が向けられることもあります。Cultures that celebrate an internal locus encourage successful people to believe their outcomes are purely the result of their own effort, underrating luck and circumstance, the meritocratic hubris that Michael Sandel criticized in The Tyranny of Merit. Conversely, unlucky people may be unfairly blamed for having the wrong attitude, which compounds their disadvantage.
出来事を振り返る際に、「自分の行動が寄与した部分」と「運や環境が寄与した部分」の両方を書き出す習慣をつけましょう。成功したときは運の寄与を認めて謙虚さを保ち、失敗したときは自分が変えられた部分だけを次の行動計画に落とし込みます。他者を評価するときも同じ二分法を適用すれば、不当な非難や過剰な称賛を避けられます。When reviewing events, write down both the part your own actions contributed and the part luck or circumstance contributed. After successes, acknowledge the role of luck to stay humble; after failures, translate only the parts you could have changed into your next action plan. Applying the same two-part analysis when evaluating others helps you avoid both unfair blame and excessive praise.
