Often we rely on other people’s behavior to guide our own. While this type of observational learning or use of heuristics can be an adaptive strategy, it can also lead you astray if your goals are different than those of others or if the information used by those others to guide their behavior does not apply to you. In such cases, a more effortful processing style is required.

The asymmetric pattern of wear on this door is an example of erosion, but there is a confound in this unobtrusive measure.
