On Good Judgment and Decision-Making: The Science and Practice

Imagine you’ve made two decisions. One has resulted in a loss of 10 thousand dollars, while the other resulted in a gain of 10 thousand dollars. Would you say that the former was a bad decision, and the latter was a good one?

The first response that usually comes to everyone’s mind is “of course, the second decision was better”. But this is not necessarily the case. Can you think of a scenario where your response would be the opposite?

“How we pay attention to the present moment largely determines the character of our experience and, therefore, the quality of our lives. Mystics and contemplatives have made this claim for ages—but a growing body of scientific research now bears it out.”
