In July 1838, Charles Darwin, then 29, sat down to make a decision that would alter the course of his life. The decision he was wrestling with was not related to scientific questions about the origins of species. It was a different kind of decision — existential as well, but of a more personal nature: Should he get married?
Darwin’s method for making this decision would be recognizable to many of us today: He made a list of pros and cons. Under the heading “not marry” he noted the benefits of remaining a bachelor, including “conversation of clever men at clubs”; under “marry” he included “children (if it please God)” and “charms of music and female chitchat.”
Even if some of Darwin’s values seem dated, the journal entry is remarkable for how familiar it otherwise feels. Almost two centuries later, even as everything else in the world has changed, the pros-versus-cons list remains perhaps the only regularly used technique for adjudicating a complex decision. Why hasn’t the science of making hard choices evolved?
In fact, it has, but its insights have been underappreciated. Over the past few decades, a growing multidisciplinary field of research — spanning areas as diverse as cognitive science, management theory and literary studies — has given us a set of tools that we can use to make better choices. When you face a complex decision that requires a long period of deliberation, a decision whose consequences might last for years or even decades, you are no longer limited to Darwin’s simple list.
