For Christmas 2015 the writers behind the hit TV show QI and international bestsellers return with a brand new book, proving once again that everything you think you know is wrong. The Third Book of General Ignorance gathers together 180 questions, both new and previously featured on the QI's popular 'General Ignorance' round.For the past decade, the QI team have been patiently correcting the myths, misunderstandings and misplaced certainties that go to make up 'general knowledge'. The first Book of General Ignorance, published in 2006, became an instant international bestseller and has been translated into 29 languages. The Second Book of General Ignorance in 2010 set the record straight on hundreds more areas of everyday wrongness. Now, the QI team returns to complete the trilogy. The Third Book of General ignorance gathers together 180 more questions to which the answers all seem perfectly obvious. Some have appeared in the BBC TV programme's 'General Ignorance' round, but many appear here for the first time.

What they prove, beyond all reasonable doubt, is that none of us know anything at all.
