It's becoming something of a New Year ritual. For almost a decade, the website www.edge.org  has been asking a selection of eminent thinkers and scholars to answer a single question and publishing the results on 1 January.
In the past it has presented such posers as "What do you believe is true, even though you cannot prove it?" and "What is the most important invention of the past 2,000 years?"
This year Edge wanted to know: "What have you changed your mind about and why?" As usual, it's a good question. And the responses of the likes of Steven Pinker and Helena Cronin are as fascinating and weighty as one would imagine.
But we cannot help wishing that some of that formidable bank of grey matter could be pointed in a more mundane direction too from time to time.
Could this stellar brains-trust not be asked to tackle a few supplementary questions? We can think of a few. How about: "Why did Network Rail schedule extensive engineering works over the busy Christmas holiday period?" And: "What is it about England and penalties?" While we're at it how about a definitive answer to: "Why did the chicken cross the road?" And finally: "What is it about the evening of 31 December that compels us to stay up too late, pay more than is reasonable for services and drink more than is sensible?"
While you're pondering on that, we would like to wish all our readers a very happy and (suitably questioning) New Year.
