When you fill out a choice list, you may feel uncertain about whether you prefer the left or right payment option. On the second decision screen, we will ask you to select a button to indicate how certain you are how much money the earlier payment is worth to you in terms of dollars at the later payment date.
In this question, we are interested in your uncertainty about your own preferences regarding these payments.
Example: Suppose that on the first decision screen you indicated that you valued $20 in 15 days somewhere between $6 and $7 today. Your second decision screen would look like this.
