What is your dangerous idea?

Every year Edge poses a question meant to stimulate rational thinkers in the empirical world. In 2006 Steven Pinker suggested "What is your dangerous idea?", not dangerous because it's an ultimate weapon or a diabolical theory, dangerous because it may be true - or it might cause you to ask a difficult question.

Charles Seife suggested that nothing can be more dangerous than nothing, Susan Blackmore asked if everything might in fact be pointless. Habitual controversy magnet Richard Dawkins on the subject of eugenics asks "what is the moral difference between breeding for musical ability and forcing a child to take music lessons"

I'm beguiled by dangerous ideas, I love to watch a stand-up comedian who is pushing the boundary of what the audience regards as acceptable. It's delicious when they tell a joke that excedes the boundary but is so funny that everybody laughs before they've had a chance to filter it as 'unacceptable content' it's a very piquant laugh that leaves the audience complicit in the 'crime'.

What's your dangerous idea? Or would you like to guess which one of the following I may believe today...

• A vote is not a right, it should be earned
  
  
• Some countries would benefit from benevolent colonialism
  
  
• Fans of celebrity/talent shows should be sterilised
  
  
• The smarter you are, the less happy you'll be
