I earned this muffin: narrative bias and performance

A great post on how cognitive bias can affect training performance:

After more and more questioning, we started to uncover that her day was filled with little treats like this that she had “earned.” Because these were always in the context of some reward, they didn’t seem off-track, or not fitting within her diet. However, what she wasn’t aware of was the treats often happened much more often than she cared to realize.

This is narrative bias in action. You and I fall victim to the exact same thing.
