data on individual responses". In the programme, survey methodology experts described the results as "unlikely", saying there were "some serious flaws with this study", that the design of the survey displayed "poor practice", and that the questions were badly written and with poor consistency risking respondents agreeing things they actually disagree with. Inconsistencies in responses suggested lack of clarity in the questions: "when asked how many Jewish people were murdered during the Holocaust: only 5 people in the entire survey gave an answer of zero ... so that's one quarter of 1% ... a figure inconsistent with the 5% (figure) of people (who) deny the Holocaust occurrence". They compared the poll to a US study from the 1990s that, due to "confusing multiple negatives" in its questions, estimated the number of Holocaust deniers in the US at more than 20% when the correct number was more like 2% of the population. Matthew Parris wrote that the Holocaust Memorial Day Trust had "defamed Britain", suggesting the Trust has designed its survey from a desire to produce bad news for effect.
