重点摘要
1. 进化心理学通过我们的祖先历史解释人类行为
“人类行为既是我们天生人性和独特个人经历与环境的产物。”
进化适应。 我们的大脑进化是为了解决祖先面临的适应性问题，如寻找配偶、与他人合作和避免危险。这些心理机制至今仍影响着我们的行为，即使在与祖先环境截然不同的现代环境中。
普遍人性。 进化心理学认为存在一种普遍的人性——一套所有人类共享的天生心理适应。这解释了为什么某些行为和偏好在所有文化中都存在。同时，个体差异源于这些适应与独特环境和经历的互动。
- 进化解决的关键适应性问题：
- 寻找和吸引配偶
- 与他人合作
- 避免捕食者和其他危险
- 获取资源和地位
- 照顾后代
2. 男性和女性由于生物差异有不同的交配策略
“由于生殖生物学的不对称性，男性的生殖成功主要受限于他们能接触到的女性数量，而女性的生殖成功并不会随着她们能接触到的男性数量线性增加。”
父母投资。 女性通过怀孕和哺乳在生殖上投入更多，而男性则可能与多名伴侣繁殖。这导致了不同的最佳交配策略：
- 男性策略：寻求配偶数量
- 女性策略：寻求配偶质量
性选择。 这些不同的策略通过性选择导致了男性和女性在心理和身体上的差异。男性竞争获取女性，而女性在选择配偶时更为挑剔。这解释了许多性别差异，如攻击性、冒险行为和配偶偏好。
3. 身体吸引力是基因健康和生育能力的指标
“因此，美貌似乎是个体的一个客观且定量的属性，如身高和体重。”
诚实信号。 我们认为有吸引力的身体特征，如面部对称、皮肤清晰和理想的身体比例，是基因质量和健康的诚实信号。我们的祖先被这些特征吸引，拥有更成功的后代。
普遍标准。 尽管存在一些文化差异，美的标准在各文化中大体上是普遍的。甚至婴儿也表现出对美丽面孔的偏好，这表明其具有天生的基础。
- 关键吸引特征及其信号价值：
- 面部对称：良好的基因，发育稳定
- 皮肤清晰：健康，抗寄生虫能力
- 理想的腰臀比：女性的生育能力
- 男性的肌肉体格：力量，战斗能力
4. 婚姻和家庭动态受进化压力的影响
“父母被设计成不投资于有缺陷的孩子。”
父权确定性。 被戴绿帽子的可能性（无意中抚养他人的孩子）塑造了男性心理，使其对不忠迹象敏感。这解释了男性性嫉妒和配偶监护行为等现象。
父母投资。 父母进化出更多地投资于具有更大生殖潜力的孩子。这导致了以下现象：
- 对亲生子女的投资多于继子女
- 偏爱更健康、更有吸引力的孩子
- 基于父母资源的性别偏向投资
亲属选择。 我们进化出更多地与近亲合作。这解释了家庭动态，如：
- 母亲与孩子之间的关系比父亲更亲密
- 外祖父母比内祖父母更为投入
- 兄弟姐妹竞争和出生顺序效应
5. 犯罪和暴力源于男性对配偶和资源的竞争
“犯下假阴性错误的后果对生存和生殖成功的危害远比犯下假阳性错误的后果严重得多，因此进化应当偏向于那些使其携带者倾向于过度推断潜在无害现象背后意图和代理的心理机制。”
男性竞争。 大多数暴力犯罪是由年轻男性为吸引配偶而竞争地位和资源所致。这解释了以下现象：
- 所有社会中男性犯罪率更高
- 暴力犯罪在年轻成年期达到高峰
- 犯罪常因地位挑战或配偶竞争而引发
冒险行为。 男性进化出更多冒险行为，因为成功的生殖回报更高。这导致了男性犯罪率和创造性成就更高。
- 犯罪的进化根源：
- 对配偶和资源的竞争
- 追求地位的行为
- 为潜在回报冒险
- 配偶监护和性嫉妒
6. 经济和政治不平等有进化根源
“失败的男人常常会找借口说‘成功不值得努力。’对女性来说，这不仅是借口，而是显而易见的事实。”
追求地位。 男性进化出通过追求地位和资源来吸引配偶。这驱动了男性在经济和政治行为中的许多表现，包括：
- 男性在职业竞争中的更大竞争性
- 男性在商业和政治中的更高冒险性
- 男性对高地位职业的偏好
性别差异。 男性和女性心理的进化差异导致了经济不平等：
-
男性更关注资源获取
-
女性偏好工作与生活的平衡
-
职业兴趣和能力的性别差异
-
不平等的进化解释：
-
男性追求地位的行为
-
冒险偏好的性别差异
-
进化出的职业兴趣
-
配偶偏好塑造的行为
7. 宗教和群体冲突源于天生的心理机制
“我们可能相信上帝，正如女性必须不断拍打男性以使其清醒，或性骚扰如此猖獗一样。”
代理检测。 我们进化出对代理或意图迹象的高度敏感，即使在无生命事件中。这使我们倾向于相信超自然代理，并促成宗教信仰。
联盟心理。 我们进化出形成合作群体并与其他群体竞争。这是以下现象的基础：
- 民族中心主义和内群体偏好
- 仇外心理和群体间冲突
- 宗教和意识形态部落主义
错误管理。 我们的大脑进化出最小化代价高昂的错误，即使这意味着更频繁但代价较低的错误。这导致了：
- 倾向于相信超自然代理（比错过真实威胁的代价低）
- 男性对女性性兴趣的过度感知
- 群体间感知中的民族中心偏见
8. 文化是人类进化的产物，而非独立于生物学
“文化是人类独特的适应方式，但文化也是生物学上进化的。”
基因-文化共进化。 文化和生物学在整个人类进化过程中相互影响。文化实践可以创造新的选择压力，导致基因适应。
普遍人类文化。 尽管表面文化特征各异，但所有人类社会中存在许多文化普遍现象。这反映了我们共享的进化心理。
- 基因-文化共进化的例子：
- 乳糖酶持久性与乳制品农业共同进化
- 抗疟疾基因随农业传播
- 大脑变化与语言发展共同进化
9. 现代行为常常与我们的祖先环境不匹配
“人类大脑难以理解和处理在祖先环境中不存在的实体和情境。”
进化不匹配。 许多现代问题源于我们的进化心理不适应新环境。例子包括：
- 由于过度摄入高热量食物导致的肥胖
- 由于信息过载和社交媒体导致的焦虑
- 在现代情境中难以评估风险
草原原则。 我们的大脑难以完全理解和处理在祖先环境中不存在的实体和情境。这导致了以下现象：
-
将媒体人物视为真实的社会关系
-
难以直观地理解大数字或抽象统计
-
将社会本能误用于现代组织环境
-
现代不匹配：
-
不健康的饮食和久坐的生活方式
-
信息过载和社交媒体成瘾
-
色情和不现实的美标准
-
短期思维导致的环境破坏
