Why Effort Is Useless: Because It Determines Your Life | Mr & Mrs Gao

Original​

🧬 命運與遺傳的基礎​

影片指出人生的根本由**命運（基因遺傳）**所決定，這是指你從父母那裡獲得的一切，包括財產、地位、家庭環境和身體（基因）。

  • 不遺傳的後天屬性：知識和技能 。
  • 會遺傳的先天屬性：身高、體重、相貌、智商、性格、天賦 。
  • 遺傳率的定義：基因遺傳後，受環境影響而發生改變的機率大小 。

🧠 智商（IQ）的遺傳與環境​

  • 智商遺傳率：約在 54% 到 80% 之間 。
  • 年齡與遺傳率的關係：智商的遺傳率會隨著年齡的增加而不斷增加，人會越來越貼近自己的基因設定。
  • 青春期是分水嶺：
    • 青春期之前（約十幾歲前）：IQ主要受環境影響，約50% 。
    • 青春期之後：基因特性會迅速展現並佔據主導 。這解釋了有些孩子突然開悟成績猛進，或有些孩子突然退步的現象。
    • 教育的影響：青春期之後，教育（如拼命補課）對成績的影響不大，因為此時主要靠基因決定 。

🧍 身體與天賦的遺傳率​

  • 指紋（最高遺傳率）：達到 98% 。影片以馬來西亞同卵雙胞胎涉毒案為例，說明即使是雙胞胎，2%的環境因素也會讓指紋不同，使其無法被區分判罪。
  • 體重：遺傳率高達 88%，影片認為胖子不是因為懶惰或貪吃，而是基因影響太大，減肥比一般人困難百倍以上 。
  • 身高：遺傳率約 66% 。
  • 性格：遺傳率在 40% 到 60% 之間，可塑性較高。家長應在青春期之後，將教育重點從學習轉向性格培養。
  • 音樂天賦：是所有天賦中遺傳率最高的，達到 92% 。
  • 精神疾病：越嚴重的精神疾病，遺傳率越高（如精神分裂82%、躁鬱症83%、ADHD80%）。

💡 結論：基因與努力的關係​

  • 努力無法戰勝遺傳：努力無法改變基因，只能對遺傳的特徵進行修飾和雕琢，且影響通常是短期的。
  • 成功公式：人生的成功是基因和努力的「相乘」關係，而不是相加 。
  • 如果你是「零天賦」（基因分數0），再怎麼努力（分數1-5），結果永遠是0 。
  • 如果你是「天才」（基因分數3），即使不努力（分數0），結果也是3；最大努力（分數5）結果是6，超越普通人的極限。
  • 公平教育的反思：公立教育機會看似公平，但由於每個人的基因天賦不同，最終反而會帶來最不公平的差距 。

🧬 Fundamentals of Fate and Inheritance​

The video suggests that the foundation of a person's life is determined by fate (genetic inheritance), which refers to everything you receive from your parents, including assets, status, family environment, and physical body (genes).

  • Acquired Attributes Not Inherited: Knowledge and skills.
  • Innate Attributes That Are Inherited: Height, weight, appearance, intelligence quotient (IQ), personality, and talent.
  • Definition of Heritability: The probability that a genetically inherited trait will change due to environmental influence

🧠 Inheritance and Environment of Intelligence (IQ)​

  • IQ Heritability Rate: Approximately 54% to 80%.
  • Age and Heritability: The heritability of IQ continuously increases with age; people increasingly align with their genetic predisposition.
  • Adolescence as the Turning Point:
    • Before Adolescence (roughly before the teens): IQ is mainly influenced by the environment, about 50%.
    • After Adolescence: Genetic traits rapidly emerge and become dominant. This explains why some children suddenly experience a breakthrough in academic performance, while others suddenly decline.
    • Impact of Education: After adolescence, education (such as intensive tutoring) has little effect on academic performance, as it is primarily determined by genes at this stage.

🧍 Heritability of Body and Talent​

  • Fingerprints (Highest Heritability): Reaches 98%. The video cites the example of the Malaysian identical twin drug case, illustrating that even in twins, the 2% environmental factor causes fingerprint differences, making it impossible to distinguish them for sentencing.
  • Body Weight: Heritability is as high as 88%. The video posits that obesity is not due to laziness or gluttony but to significant genetic influence, making weight loss hundreds of times harder for them than for the average person.
  • Height: Heritability is approximately 66%.
  • Personality: Heritability is between 40% and 60%, indicating higher plasticity. Parents should shift the focus of education from academics to personality development after adolescence.
  • Musical Talent: Has the highest heritability among all talents, reaching 92%.
  • Mental Illness: The more severe the mental illness, the higher the heritability (e.g., Schizophrenia 82%, Bipolar Disorder 83%, ADHD 80%).

💡 Conclusion: The Relationship Between Genes and Effort​

  • Effort Cannot Conquer Inheritance: Effort cannot change genes; it can only modify and refine inherited traits, and the impact is usually short-term.
  • Success Formula: Success in life is a "multiplicative" relationship between genes and effort, not additive.
  • If you have "zero talent" (gene score 0), no matter how much effort you put in (score 1-5), the result is always 0.
  • If you are a "genius" (gene score 3), even if you don't put in effort (score 0), the result is 3; with maximum effort (score 5), the result is 6, surpassing the limits of ordinary people.
  • Reflection on Equal Education: Public education opportunities may seem fair, but due to the different genetic endowments of each person, they ultimately lead to the most unfair gaps.
