Survey researchers, and those who rely on survey research, justify invalid, inaccurate, results. For example, in a Chicago Tribune article it’s stated that a 2015 Compass Group report based on survey research “is not . . . valid”. That does not stop the administrator of the administrator of the survey, Jean-Francois Gauthier, CFO of Compass Group, from justify these results: they’re “the best . . . we have”. Other justifications for accepting invalid survey resource results include: the results are good “for this type of study” and the results are “food for thought”. Survey researchers and those who rely on survey research accept, justify, and use any results they obtain.
For a further discussion of the justification of invalid, inaccurate, results by survey researchers and those who rely on survey research, see my book, The Problem with Survey Research, esp. pp. 267-72.
