 Imagine a meadow whose plants are loaded with insects but few are in flight. Then, this meadow is a more favorable environment for a bird that gleans rather than hawks. In a similar fashion, a decision-making environment might be more favorable for one decision-making strategy than for another. Just as it would be “irrational” for a bird to hawk rather than glean, given the choice for this meadow, so too what may be an irrational decision strategy in one environment may be entirely rational in another.
