Glossary » mundane realism
the extent to which a study, such as user testing, matches the real-world situation to which its results will be applied. This is an example of an external validity concern. This means matching the types of users being tested and the equipment and context in which they’re tested. For instance, testing in a usability lab may be less realistic than testing in an office setting (though the lab may be preferable for other reasons, such as available recording equipment or the prevention of interruptions).
