Even Brewer, the author of the infographic, publicly admitted in 2012 that he couldn’t back up any of the statistics and asked people to stop sharing it. Brewer claims to have used statistics from a survey by an organization called the Jenkins Group, though the group itself says the statistics were incorrectly attributed to them. Brewer has never been able to provide any other source of the numbers he used in the infographic.
The questionable statistics seem to have originally come from a 2011 Mental Floss article, which claimed to have taken them from a Jenkins survey from 2003. Mental Floss has updated the original article saying they have no idea where the statistics came from, either.
Hey just FYI, that statistic is bullshit
