In the following TED talk James Flynn explains how we have improved our cognitive abilities over time - I have previously argued that this supports my assertion that, as a population, we can do Interactive Democracy. But he also claims that we are becoming "ignorant of history and of other countries" and, therefore, we "can't do politics". This runs counter to my argument. But I'd suggest that by debating each issue and by ensuring the quality of that debate through presenting it in a logical manner and ensuring it is factually correct, then we can educate ourselves about history and geopolitics and thus are capable of "do[ing] politics".
(Switzerland has being doing direct democracy for more than 150 years. Back then hardly anyone was as educated as the average person today!)
