There is a compelling drama going on in our minds, a filmlike plot between two main characters with twists, dramas and tensions. These two characters are the impulsive, automatic, intuitive System 1, and the thoughtful, deliberate, calculating System 2. As they play off against each other, their interactions determine how we think, make judgments and decisions, and act.
我们的脑海中正在上演一出引人入胜的戏剧，两个主要角色之间的情节像电影一样曲折、戏剧化和紧张。这两个角色分别是冲动、自动、直觉的 "系统 1 "和深思熟虑、深谋远虑、精打细算的 "系统 2"。在他们相互博弈的过程中，他们之间的互动决定了我们如何思考、做出判断和决定，以及如何行动。

System 1 is the part of our brain that operates intuitively and suddenly, often without our conscious control. You can experience this system at work when you hear a very loud and unexpected sound. What do you do? You probably immediately and automatically shift your attention toward the sound. That’s System 1.
系统 1 是我们大脑中直觉和突然运作的部分，通常不受我们意识的控制。当你听到一个非常响亮且出乎意料的声音时，你就能体验到这一系统在工作。你会怎么做？你可能会立即自动将注意力转移到声音上。这就是系统 1。

This system is a legacy of our evolutionary past: there are inherent survival advantages in being able to make such rapid actions and judgments.
这套系统是我们进化过程中遗留下来的：能够做出如此迅速的行动和判断，具有与生俱来的生存优势。

System 2 is what we think of when we visualize the part of the brain responsible for our individual decision-making, reasoning and beliefs. It deals with conscious activities of the mind such as self-control, choices and more deliberate focus of attention.
当我们想象大脑中负责个人决策、推理和信念的部分时，就会想到系统 2。它负责有意识的思维活动，如自我控制、选择和更深思熟虑的注意力集中。

For instance, imagine you’re looking for a woman in a crowd. Your mind deliberately focuses on the task: it recalls characteristics of the person and anything that would help locate her. This focus helps eliminate potential distractions, and you barely notice other people in the crowd. If you maintain this focused attention, you might spot her within a matter of minutes, whereas if you’re distracted and lose focus, you’ll have trouble finding her.
例如，想象你正在人群中寻找一位女士。你的大脑会刻意将注意力集中在任务上：回想这个人的特征以及任何有助于找到她的东西。这种专注有助于排除潜在的干扰，你几乎不会注意到人群中的其他人。如果你保持这种专注的注意力，你可能会在几分钟内发现她，而如果你分心并失去注意力，你将很难找到她。

As we'll see in the following blinks, the relationship between these two systems determines how we behave.
正如我们在接下来的闪烁中看到的，这两个系统之间的关系决定了我们的行为方式。
