EigoPro 準1級 読解 — The Making of Experts

We are fond of crediting genius. The chess grandmaster, the concert violinist, the surgeon whose hands never falter—each seems to possess a gift that the rest of us simply lack. Yet decades of research into the psychology of expertise tell a less romantic story. When the psychologist Anders Ericsson studied elite performers across fields as varied as music, athletics, and medicine, he found that the single most reliable predictor of mastery was not innate talent but the accumulation of a particular kind of effort he called "deliberate practice." Deliberate practice is not mere repetition. Hammering out the same scales for an hour, or replaying a game one already knows how to win, produces little improvement; such activity is comfortable, and comfort is precisely the enemy. What distinguishes deliberate practice is that it is effortful and uncomfortable by design. The learner works at the very edge of current ability, attacking specific weaknesses, courting failure, and relying on immediate, often harsh, feedback to correct each error before it hardens into habit. This is why a coach or teacher matters so much: an outside eye can identify the flaws that the performer, lulled by familiarity, can no longer perceive. The implications are bracing. If expertise is largely built rather than bestowed, then the comforting excuse of "I'm just not gifted" begins to dissolve. But the theory has its critics. Talent, they argue, has not been banished so much as relocated: some people may possess a greater capacity to sustain the grinding concentration that deliberate practice demands. Moreover, thousands of hours of training are useless without access to good teachers, leisure time, and early encouragement—resources distributed by accident of birth. The democratic promise of deliberate practice, then, comes with a quiet caveat. Effort may indeed forge expertise, but the opportunity to exert it is not handed out equally.

問 1

What is the main idea of the passage?

  • Expertise depends far more on a demanding, focused kind of practice than on inborn talent, though opportunity to practise is unevenly distributed.
  • Innate genius is the only reliable predictor of mastery across professional fields.
  • Repeating a skill for thousands of hours guarantees that anyone can become an elite performer.
  • Coaches and teachers are unnecessary once a learner has accumulated enough practice.
Phrase

the single most reliable predictor of mastery was not innate talent but ... deliberate practice

本文の論旨は「熟達は生まれつきの才能より特殊な練習で決まる、ただし練習機会は不平等」。

選択肢の解説Choice Analysis

「Expertise depends far more on a demanding, focused kind of practice than on inborn talent, though opportunity to practise is unevenly distributed.」

正解

第1段で『熟達の最も信頼できる予測因子は生来の才能ではなく deliberate practice だ』と述べ、第2段でその性質を説明し、第3段で『機会は出生の偶然で不平等に配分される』と留保する。よって『熟達は才能より厳しく集中的な練習に依存するが、その練習機会は不平等に配分されている』が主旨。

  • 「Innate genius alone is the only reliable predictor there is of mastery right across every one of the professional fields.」

    = 生来の天才だけが唯一の予測因子 ━ 本文はまさにこれを否定し『not innate talent but deliberate practice』と述べているので正反対。

  • 「Simply repeating a skill for many thousands of hours will guarantee that absolutely anyone can become an elite performer.」

    = 数千時間の反復が誰でもエリートにすると保証する ━ 第2段で『単なる反復はほとんど上達を生まない』、第3段で『良い教師等がなければ無意味』と述べており保証はしていない。

  • 「Coaches and teachers alike become entirely unnecessary once a learner has accumulated a sufficient number of practice hours.」

    = コーチや教師は不要 ━ 第2段は『外部の目が見えない欠陥を指摘するから coach がとても重要』と述べており逆。

  • Effort, not luck, was the most reliable predictor of success.

    成功の最も信頼できる予測因子は運ではなく努力だった。

  • Mastery is built rather than bestowed.

    熟達は授けられるのではなく築かれるものだ。

  • The promise comes with a quiet caveat.

    その約束には静かな但し書きが付いている。

主旨設問は全段落の論理 (主張→説明→留保) を束ねた選択肢を選ぶ。一段落だけを誇張した極端肢 (only / guarantees / unnecessary) は外す。

問 2

According to the passage, what distinguishes deliberate practice from ordinary repetition?

  • It avoids failure in order to keep the learner motivated and relaxed.
  • It is deliberately effortful and uncomfortable, targeting specific weaknesses with immediate feedback.
  • It relies on repeatedly performing tasks the learner has already mastered.
  • It can only be carried out alone, without any outside guidance.
Phrase

it is effortful and uncomfortable by design ... attacking specific weaknesses ... relying on immediate ... feedback

⚡ひとことで

deliberate practice は『意図的に苦しく・弱点を狙い・即時フィードバックに頼る』点が普通の反復と違う。

選択肢の解説Choice Analysis

「It is deliberately effortful and uncomfortable, targeting specific weaknesses with immediate feedback.」

正解

第2段で『単なる反復ではない』と前置きし、deliberate practice を effortful and uncomfortable by design・attacking specific weaknesses・relying on immediate ... feedback と特徴づける。これを言い換えた『意図的に努力を要し不快で、弱点を狙い即時フィードバックを使う』が正解。

  • 「It relies upon repeatedly performing only the tasks that the learner has already mastered.」

    = すでに習得した課題を反復する ━ 本文は『既に勝てる試合を再現しても上達しない』と述べており、これは普通の反復の説明で逆。

  • 「It carefully avoids all failure in order to keep the learner both motivated and relaxed.」

    = 失敗を避ける ━ 本文は『失敗を招き (courting failure)』と述べておりむしろ失敗に向き合う。

  • 「It can only ever be carried out entirely alone, without any form of outside guidance at all.」

    = 一人でしか行えない ━ 本文は coach や teacher の役割を重視しており『一人だけ』とは言っていない。

❝例文

  • Real progress is uncomfortable by design.

    本当の上達は意図的に不快なものだ。

  • She works at the very edge of her ability.

    彼女は能力の限界ぎりぎりで取り組む。

  • Correct the error before it hardens into habit.

    誤りが習慣に固まる前に正しなさい。

💡Tip · 覚えるコツ

detail 設問は本文の語を別語に置換した肢が正解 (effortful and uncomfortable→deliberately effortful, specific weaknesses→specific weaknesses)。本文と正反対の語 (avoids failure) を含む肢は罠。

問 3

What objection do critics of the theory raise, according to the third paragraph?

  • Ericsson's research deliberately excluded fields outside of music.
  • Talent may still matter as a capacity to sustain intense concentration, and the resources needed to practise are not equally available.
  • Deliberate practice has been shown to harm elite performers over time.
  • Most experts in fact achieve mastery without any practice at all.
Phrase

Talent ... has not been banished so much as relocated ... resources distributed by accident of birth

⚡ひとことで

批判者の論点=才能は『集中を持続する能力』として残る+練習資源は出生で不平等。

選択肢の解説Choice Analysis

「Talent may still matter as a capacity to sustain intense concentration, and the resources needed to practise are not equally available.」

正解

第3段で批判者は『才能は追放されたのではなく移転しただけ』とし、『grinding concentration を持続する能力』を才能として残す。さらに good teachers・leisure time・early encouragement は『出生の偶然』で配分されると述べる。これを束ねた選択肢が正解。

  • 「Deliberate practice of this kind has been repeatedly shown to harm even the elite performers over the longer term.」

    = エリートに害を与えると示された ━ 練習が害になるという記述は本文にない。

  • 「Most of the experts who were studied in fact achieved their mastery without doing any deliberate practice at all.」

    = 練習なしで熟達する ━ 批判者の主張は練習の重要性を否定するものではなく、才能と機会を問題にしている。

  • 「Ericsson's original research deliberately excluded every single field of expertise lying outside of music itself.」

    = 音楽以外の分野を除外した ━ 第1段は music, athletics, medicine と『多様な分野』を研究したと明記しており逆。

▦Collocation

❝例文

  • Talent was not banished so much as relocated.

    才能は追放されたというより移転しただけだった。

  • Few can sustain that grinding concentration.

    あの過酷な集中を持続できる者は少ない。

  • Opportunity is not handed out equally.

    機会は平等に配られはしない。

💡Tip · 覚えるコツ

『批判者の論点』設問は批判パラグラフ (But the theory has its critics 以降) に絞って読む。本文に存在しない害・除外を持ち出す肢は『本文にない』型の罠。
