How DNA Truly Affects Your Personality
DNA对性格的真正影响
科学家通过分析超过114万人的海量数据，发现了1260个与人类性格相关的基因变异。然而，这些基因变异对性格差异的解释度还不足10%，因此仅凭基因无法预测一个人的性格。研究人员强调，教育、社会经历等后天环境因素在性格塑造中起着更为关键的作用。

科学家发现了1260个与人类性格相关的基因变异。identified 发现了 / genetic variants 基因变异 / linked to 与……相关
A large international study looked at data from over 1.14 million people.
一个大型国际研究团队分析了超过114万人的数据。international study 国际研究 / looked at data 分析了数据
The team examined extraversion, agreeableness, and conscientiousness.
研究团队考察了外向性、宜人性和尽责性。examined 调查、研究了 / extraversion 外向性 / agreeableness 宜人性 / conscientiousness 尽责性
They also studied neuroticism and openness to experience.
他们还同时研究了神经质和经验开放性。neuroticism 神经质 / openness to experience 经验开放性
Together, these DNA variants explain only 4.8% to 9.3% of each trait.
这些基因变异对各项性格特质的解释度仅为4.8%至9.3%。DNA variants 基因变异 / explain 解释 / each trait 每项特质
The researchers emphasize that there is no single personality gene,
研究人员强调，并不存在单一的'性格基因'，emphasize 强调 / personality gene 性格基因
so an individual's character cannot be predicted from DNA alone.
因此无法单凭DNA来预测一个人的性格。individual's character 个人性格 / predicted 被预测 / DNA alone 仅凭DNA
Surprisingly, innate factors like family environment have very little effect.
令人惊讶的是，像家庭环境这样的先天因素几乎没有影响。innate factors 先天因素 / family environment 家庭环境 / very little effect 几乎没有影响
Instead, acquired factors play a much larger role in shaping who we are.
相反，后天因素在塑造我们的性格方面起着大得多的作用。acquired factors 后天因素 / play a larger role 发挥更大作用 / shaping who we are 塑造自我
Things like education, income, and social experiences matter far more.
教育、收入和社会经历等因素要重要得多。social experiences 社会经历 / matter far more 重要得多

a simple 20-minute test is still the most reliable way to measure personality.
简单的20分钟测试依然是评估性格最可靠的方法。reliable way 可靠的方法 / measure personality 评估性格
He believes that debating nature versus nurture is now outdated,
他认为，争论先天与后天如今已经过时了，debating 争论 / nature versus nurture 先天对后天 / outdated 过时的
because our genetics and our environment always work together.

Quiz 🧠
Q1. Can a person's DNA alone decide their entire personality?
查看答案
✅ No
DNA只能解释一小部分性格特征。生活环境和人生经历对性格塑造同样起着重要作用。
DNA only explains a small part of our traits. Experiences and environment also shape who we are.
Q2. What does 'outdated' mean in 'an outdated idea'?
查看答案
✅ No longer useful
“outdated”意为过时的、陈旧的，指不再适用或已被淘汰的事物。
'Outdated' describes something old-fashioned that is no longer suitable or accepted today.
Q3. Human genetics only partly shape personality. What else plays a major role?
查看答案
✅ Life experiences
除了遗传因素外，教育、社会经历等后天环境因素在性格塑造中也起着关键作用。
Genetics work together with our environment. Things like education and social experiences strongly influence our character.
Dialogue 🎧
Liam: Did you see that huge new DNA study?
Liam: 你看到那项最新的重磅DNA研究了吗？
Liam: They found 1,260 genetic variants linked to personality!
Liam: 他们居然发现了1260个与性格相关的基因变异！
Emma: Whoa, really? I thought our character was mostly shaped by how we grew up.
Emma: 哇，真的吗？我一直以为性格主要是在成长过程中塑造的呢。
Liam: Right, but they analyzed over 1.14 million people to check traits like extraversion and neuroticism.
Liam: 是的，不过研究人员分析了超过114万人的数据，调查了外向性和神经质等性格特质。
Emma: That is a massive sample! So can scientists predict our whole personality now?
Emma: 样本量真够庞大的！那科学家现在能预测我们的全部性格了吗？
Liam: Actually, no.
Liam: 其实并不能。
Liam: All those variants together only explain 4.8% to 9.3% of each trait.
Liam: 所有这些基因变异加在一起，也只能解释各项特质的4.8%到9.3%。
Emma: That's tiny! So there is no single master personality gene after all?
Emma: 比例太小了！所以说到底，根本就不存在决定性格的单一核心基因对吧？
Liam: Exactly. There's no single gene doing the work.
Liam: 没错，没有哪个单一基因能决定一切。
Emma: Wait, what about openness, agreeableness, and conscientiousness? Are they genetic too?
Emma: 等等，那开放性、宜人性和尽责性呢？它们也受基因影响吗？
Liam: A little bit. But acquired factors matter way more than your DNA.
Liam: 有一点点。但后天因素远比DNA重要得多。
Emma: Like what? What actually shapes us then?
Emma: 比如哪些？那到底是什么在真正塑造我们呢？
Liam: Things like education, income, and our social experiences.
Liam: 比如教育、收入以及我们的社会经历等等。
Liam: Even your family environment has little effect!
Liam: 甚至连家庭环境的影响都微乎其微！
Emma: Seriously? Even our family? That really blows my mind.
Emma: 真的吗？连家庭都没什么影响？太不可思议了。
Liam: I know!
Liam: 就是说啊！
Liam: Lead researcher Michel Nivard says debating nature versus nurture is totally outdated now.
Liam: 首席研究员米歇尔·尼瓦尔德表示，争论究竟是先天还是后天决定如今已经彻底过时了。
Emma: Because genes and environment always work together, right?
Emma: 因为基因和环境始终是一起起作用的，对吧？
Liam: Exactly.
Liam: 完全正确。
Liam: He says a simple 20-minute test is still much better at measuring personality.
Liam: 他说要评估性格，做一个20分钟的简短测试依然要有效得多。
Emma: That's a relief. I'd rather take a quick quiz than test my DNA anyway!
Emma: 那太让人省心了。反正比起做DNA检测，我更愿意做个快速小测验！
