You've read about the idea ofthinking at the margin.This refers to thinking about the small changes to your benefit and cost from doing a little bit more of something. Thinking at the margin is in contrast to all-or-nothing decision making. For example, in this class, students often don't decide to take the class and then do every last optional activity, watch every single video, etc. Students instead tend to think at the margin: will the marginal benefit (to my grade) of reading this next section of the reading assignment compare to my marginal cost (time spent)?

• Think of another example where you thought at the margin about something you wanted to do.
• Did thinking at the margin help you consider new information? Explain.
• Did thinking at the margin result in better decision making? Explain this as well.
