Self-licensing is the unconscious tendency to allow yourself to do something bad after you have done something good.

“自我纵许”指做了一些好事之后会无意识地允许自己做点不好的事。

Imagining yourself as "doing good" can sometimes lead to bad things. You eat more at Thanksgiving because you went to the gym in the morning. The "good" action somehow licenses the "bad" action, because you have a self-image as a healthy person.

觉得自己“在做好事”有时会导致一些不好的事。感恩节你吃的比之前多，因为那天早晨你去了趟健身房。“好的”的行为有时会成为“坏”行为的通行证，因为你已经树立了一个健康的自我形象。

It's what many diet experts say may be behind why so many of us fall off the diet rails on our "cheat days."

节食专家称这种“自我纵许”的心理正是我们很多人在节食的过程中偶有几天“放纵偷懒”的背后原因。
