“Consider, for example, the history of mankind’s attempts to fly. Early researchers observed strong correlations between being able to fly and having feathers and wings. Stories of men attempting to fly by strapping on wings date back hundreds of years. They were replicating what they believed allowed birds to soar: wings and feathers.
Possessing these attributes had a high correlation—a connection between two things—with the ability to fly, but when humans attempted to follow what they believed were “best practices” of the most successful fliers by strapping on wings, then jumping off cathedrals and flapping hard … they failed.
The mistake was that although feathers and wings were correlated with flying, the would-be aviators did not understand the fundamental causal mechanism—what actually causes something to happen—that enabled certain creatures to fly.
The real breakthrough in human flight didn’t come from crafting better wings or using more feathers. It was brought about by Dutch-Swiss mathematician Daniel Bernoulli and his book Hydrodynamica, a study of fluid mechanics. In 1738, he outlined what was to become known as Bernoulli’s principle, a theory that, when
“applied to flight, explained the concept of lift. We had gone from correlation (wings and feathers) to causality (lift).
Modern flight can be traced directly back to the development and adoption of this theory.
But even the breakthrough understanding of the cause of flight still wasn’t enough to make flight perfectly reliable. When an airplane crashed, researchers then had to ask, “What was it about the circumstances of that particular attempt to fly that led to failure? Wind? Fog? The angle of the aircraft?” Researchers could then define what rules pilots needed to follow in order to succeed in each different circumstance. That’s a hallmark of good theory: it dispenses its advice in “if-then” statements.”
The Power of Theory in Our Lives
How do fundamental theories relate to finding happiness in life?
The appeal of easy answers—of strapping on wings and feathers—is incredibly alluring. Whether these answers come from writers who are hawking guaranteed steps for making millions, or the four things you have to do to be happy in marriage, we want to believe they will work. But so much of what’s become popular thinking isn’t grounded in anything more than a series of anecdotes. Solving the challenges in your life requires a deep understanding of what causes what to happen.
...
just as these theories have explained behavior in a wide range of circumstances, so, too, do they apply across a wide range of questions. With most complex problems it’s rarely as simple as identifying the one and only theory that helps solve the problem. There can be multiple theories that provide insight. For example, though Bernoulli’s thinking was a significant breakthrough, it took other work—such as understanding gravity and resistance—to fully explain flight.”
