A review of 63 scientific studies has concluded that non-believers are more smug than religious people.
The paper, entitled 'The Relation Between Smugness and Religiosity: An Analysis For Stupid People Who Believe In God And Fairies And Things', was published by a team at the University Of Self-Righteousness in New York.
They found that atheists' feelings of superiority stemmed from a number of sources - including the reading of Richard Dawkins books, the behaviour of the Catholic Church, and studies showing that non-believers are more intelligent.
Atheists have been surprisingly happy with the findings. One told HuffPost UK Comedy: "This study just proves what we knew all along".
