Escape a narrow frame of thinking

Think about opportunity cost.
What if we started every decision by asking simple questions: What are we giving up by making this choice? What else could we do with the same time and money?

Pretend that your current options have disappeared.
Until we are forced to dig up a new option, we’re likely to stay fixated on the ones we already have.

Spot the narrow frame in others.
It’s easier to spot a narrow frame from the outside—watch for it as a decision adviser. “Whether or not” decisions should set off warning bells. This could also help you create a sense of alarm when your perception of things starts narrowing, while you can also help others spot them.
