Dan Ariely on irrationality in the workplace

Mckinsey asked Dan Ariely on what distinguishes a situation when an executive should trust his intuition or his gut feeling, versus one where he should really pause and think?

Dan Ariely: One way to think about it is the following: imagine you stand on a field and you have a soccer ball and you kick it. You close your eyes and you kick it and then you open your eyes and you try to predict, where did the ball fall? Imagine you do this a thousand times; after a while you know exactly the relationship between your kick and where the ball is. Those are the conditions in which intuitions are correct—when we have plenty of experience and we have unambiguous feedback.


That’s learning, right? And we’re very good at it. But imagine something else happened. Imagine you close your eyes, you kick the ball, and then somebody picked it up and moved it 50 feet to the right or to the left or any kind of other random component. Then ask yourself, how good will you be in predicting where it would land? And the answer is: terrible.


The moment I add a random component, performance goes away very quickly. And the world in which executives live in is a world with lots of random elements. Now I don’t mean random that somebody really moves the ball, but you have a random component here, which you don’t control—it’s controlled by your competitors, the weather; there’s lots of things that are outside of your consideration. And it turns out, in those worlds, people are really bad. This actually, I think, brings us to the most important underutilized tools for management, which [are] experiments. You say, I can use my intuition, I can use data that tells me something about what might happen, but not for sure, or I can implement something and do an experiment. I am baffled by why companies don’t do more experiments
