We estimate risk using a mental shortcut called the " availability heuristic."

我们使用称为“可用性启发式” 的思维捷径来估计风险。

And these mental shortcuts can lead to irrational decisions, not like falling in love or bungee jumping off a cliff, but logical fallacies that can easily be proven wrong.

脑力捷径（快速思维）导致不合理的决定，不同于热恋或悬崖上的蹦极，逻辑谬误很容易被证伪。

And this is sort of the role that habits play in our lives, is that they are these mental shortcuts, these kind of automatic scripts that you can just play whenever the situation or the context is right.

这就是习惯在我们生活中扮演的角色，它们是心理捷径，自动脚本，只要情况或环境正确，你就可以播放。
