Why Easy-to-Find Answers Can Crowd Out Better Ones
When a question is difficult, people often drift toward evidence that is easier to see, collect, or explain. Psychologists call this the streetlight effect: the search is guided by where the light falls, not necessarily by where the answer is.
The mechanism is subtle. A clear, available clue feels useful because it takes less effort to inspect. It can also make progress easier to demonstrate: a count, survey, or quick comparison looks more solid than an uncertain search through messy evidence. Gradually, the convenient measure can stand in for the real question without anyone deciding to change the goal.
How a Proxy Becomes the Answer
Imagine a team trying to understand why customers leave. It may focus on complaints that arrive through a feedback form because those are easy to sort and count. But customers who quietly stop buying may never fill out the form. The team has learned what the vocal respondents report, not necessarily what drives most departures.
That does not make visible evidence useless. It makes the gap between what is measurable and what matters important to notice. A convenient measure is a proxy—a stand-in for something harder to observe—and proxies can mislead when treated as the target itself.
Widening the Search
A useful check is to ask what evidence would answer the original question, even if it is inconvenient or absent from the current data. Then ask who or what the easy method leaves out. The answer may require a different source, more time, or an admission that the evidence is incomplete.
The practical danger is not simply missing information. It is mistaking a tidy answer for a complete one—and making decisions around the part of the problem that happened to be easiest to see.
