A memorable correlation can become a bad shortcut. The content library includes a story about browser choice predicting employee performance. Without the underlying evidence and context, that is not a sound basis for hiring or judging someone.
Ask what else could explain it
A pattern may reflect access, training, role requirements or the environment in which people work. Even a real association does not establish that changing the visible signal would change the outcome. Installing a different browser is not a job skill.
This matters beyond hiring. A customer segment may appear valuable because it receives better service or comes through a different channel. Treating the label as the cause can lead to the wrong intervention.
Return to the task
If you want evidence about a person's ability, assess relevant work. If you want to understand a customer behaviour, inspect the actual journey. Use direct observations where possible rather than an interesting proxy that is easier to collect.
For hiring, consistent questions and job-related assessment criteria are a stronger starting point than personal habits unrelated to the role. OPM's structured interview guidance describes that approach.
Write the limitation beside the finding
Record the population, period and measurement behind a pattern. Ask whether it holds in the group where you plan to use it. If the evidence is unavailable, keep the story as a prompt for investigation rather than a conclusion.
A useful signal helps you ask a better question. It becomes dangerous when it stops you asking questions at all.
