Why We Search Where It Is Easiest

The streetlight effect reveals a common bias where we only look for solutions where it is most convenient. We often ignore the actual source of our problems simply because looking elsewhere requires more effort.

This term comes from a joke about a man searching for lost keys under a streetlight, even though he dropped them in a dark park. He admits the park is where the keys actually are, but chooses the light because it makes the task easier. We see this in science and daily life when people rely on data they already have rather than finding what they actually need. It serves as a reminder to look into the shadows to solve real problems.
