Cognitive Biases: The Shortcuts of the Mind认知偏差：心智的捷径

A cognitive bias is a predictable shortcut in judgment. The brain uses shortcuts because it cannot inspect every detail from scratch. Most of the time, that efficiency is useful.认知偏差是判断中的可预测捷径。大脑使用捷径，因为它无法从零检查每个细节。大多数时候，这种效率是有用的。

The trouble starts when a shortcut feels like certainty. A quick impression can become a conclusion before the slower parts of thinking have a chance to check it.麻烦始于捷径让人感觉像确定性。快速印象可能在较慢思考有机会检查前，就变成结论。

Confirmation bias makes us notice evidence that supports what we already think. Anchoring lets the first number pull later judgments. Availability bias makes vivid examples feel more common than they are.确认偏差让我们注意支持既有想法的证据。锚定效应让第一个数字拉动之后的判断。可得性偏差让生动例子显得比实际更常见。

Sunk cost fallacy keeps us invested because we already spent effort. Spotlight effect makes us overestimate how much others notice us. Halo effect lets one good trait color the whole picture.沉没成本谬误让我们因为已经投入而继续投入。聚光灯效应让我们高估别人注意自己的程度。光环效应让一个好特质染色整幅图像。

Biases matter because they usually feel normal from the inside. You do not experience confirmation bias as bias. You experience it as seeing the obvious truth.偏差重要，是因为从内部体验时它们通常显得正常。你不会把确认偏差体验为偏差，而会体验为“看见显而易见的真相”。

That is why good decision design helps. Ask what evidence would change your mind, get a second view, write down assumptions, and revisit important choices after the emotional peak passes.这就是为什么好的决策设计有帮助。问问什么证据会改变你的想法，听取第二视角，写下假设，并在情绪高峰过去后重新审视重要选择。

The Decision Style Profile can help you notice how you choose under uncertainty. Dual Process Theory explains why many shortcuts run quickly and automatically.决策风格画像能帮助你注意自己如何在不确定中选择。双加工理论解释了为什么许多捷径快速且自动运行。

The goal is not to become bias-free. It is to become easier to correct.目标不是没有偏差，而是更容易修正。

Calling something a bias should not become a way to dismiss another person. Everyone uses shortcuts, and context often explains why a shortcut was tempting.把某件事称为偏差，不应该变成否定他人的方式。每个人都会使用捷径，而情境常能解释为什么某条捷径有诱惑力。
