Bad data PR: how the NSPCC sunk to a new low in data churnalism
when the NSPCC sent out a press release saying that one in ten 12-13 year olds [in the UK] are worried that they are addicted to porn and 12% have participated in sexually explicit videos, dozens of journalists appear to have simply played along – despite there being no report and little explanation of where the figures came from. [….] “It turns out the study was conducted by a “creative market research” [ie. pay-per-survey] group calledOnePoll. “Generate content and news angles with a OnePoll PR survey, and secure exposure for your brand,” reads the company’s blurb. “Our PR survey team can help draft questions, find news angles, design infographics, write and distribute your story.” “The OnePoll survey included just 11 multiple-choice questions, which could be filled in online. Children were recruited via their parents, who were already signed up to OnePoll.”
The NSPCC spends 25 million UKP per year on “child protection advice and awareness”, so they have the money to do this right. Disappointing.(tags: nspcc bad-science bad-data methodology surveys porn uk kids addiction onepoll pr market-research)
