sometimes we want our decisions to have a rational veneer when, in fact, they stem from a gut feeling—what we crave deep down. I suspect that in our attempts to make sure that we end up with decisions that seem well-reasoned and thoughtful, we commonly undergo a lot of unnecessary mental gymnastics and justifications, particularly when the choices are large and significant. Sometimes these rationalizations are complex and time-consuming, and sometimes we have the benefit of a software program to help us with more efficient rationalization.
