statistician Nassim Taleb called TED a "monstrosity that turns scientists and thinkers into low-level entertainers, like circus performers". He claimed TED curators did not initially post his talk "warning about the financial crisis" on their site on purely cosmetic grounds. In May 2012, venture capitalist Nick Hanauer spoke at TED University, challenging the belief that top income earners in America are the engines of job creation. TED attracted controversy when it chose not to post Hanauer's talk on their website. His talk analysed the top rate of tax versus unemployment and economic equality. TED was accused of censoring the talk by not posting it on the website. On May 7, 2012, Chris Anderson, the curator of TED, in an email to Hanauer, commented on his decision and took issue with several of Hanauer's assertions in the talk, including the idea that businesspeople are not job creators. He also made clear his aversion to the "political" nature of the talk. The National Journal reported that Chris Anderson had reacted by saying the talk probably ranked as one of the most politically controversial talks they had ever run, and they needed to be careful about when they posted it. Anderson officially responded on his personal blog, stating that TED only posts one talk every day, selected from many. Forbes staff writer Bruce Upbin described Hanauer's talk as "shoddy and dumb" while New York magazine condemned TED's move. Following a TEDx talk by parapsychologist Rupert Sheldrake, TED issued a statement saying their scientific advisors believed that "there is little evidence for some of Sheldrake's more radical claims" made in the talk and recommended that it "should not be distributed without being framed with caution". The video of the talk was moved from the TEDx YouTube channel to the TED blog accompanied by the framing language called for by the advisors. The move and framing prompted accusations of censorship, to which TED responded by saying the accusations were "simply not true" since Sheldrake's talk was still on their website. A 2013 talk by Graham Hancock, promoting the use of the drug DMT, was treated in the same way. According to professor Benjamin Bratton at University of California, San Diego, TED Talks' efforts at fostering progress in socio-economics, science, philosophy, and technology have been ineffective. Chris Anderson responded that some critics have a misconception of TED's goals, and failed to recognise that TED aimed to
