As an expert witness for Whole Foods, Kellyanne Conway gave testimony that was deemed 'fundamentally flawed' and thrown out

The DC District Court threw out Conway's survey, saying it would not give "any weight or consideration" to it because of its methodology.

The court found that the FTC's expert witness, Kent Van Liere, presented compelling evidence about the study's drawbacks, which the agency said suffered "serious and fatal design flaws, poor execution, and conclusions that are inconsistent with the survey's results," and failed to "meet basic standards" of survey research.

"My overall opinion in this matter is that Ms. Conway's survey methodology and procedures are fundamentally flawed and render her data and results unreliable," Van Liere testified, according to July 2007 court documents. "In addition, it is my opinion that her survey does not provide a reliable basis to assess the issues associated with consumer perceptions of the substitutability of products and services across food retailers."

Van Liere said Conway's response rate was "so low that her results cannot be considered reliable" and included "unqualified respondents" who could not "understand or could not complete the questions accurately." Her response rate, according to Van Liere, varied "from 6 percent to 0.5 percent" of callers the pollsters attempted to reach, and over 20% did not reside in the zip codes designated in the survey.
