Statistical Modeling, Causal Inference, and Social Science: The backseat driver principle
The driver overestimates his control over the situation (including his own car as well as others on the road). The backseat driver (“Whoa–you’re taking that curve too fast!”) underestimates the driver’s control. As a driver, I listen to the passengers because they provide a useful corrective. Even if the backseat driver is sometimes annoying, it makes sense to listen.
My principle: There is no learning without feedback. Be open to every bit of advice, criticism and praise you receive. Evaluate it, but don’t automatically believe it.
