understandinguncertainty.org was produced by the Winton programme for the public understanding of risk based in the Statistical Laboratory in the University of Cambridge. The aim was to help improve the way that uncertainty and risk are discussed in society, and show how probability and statistics can be both useful and entertaining.

Many of the animations were produced using Flash and will no longer work.

Towards the end of 2011, a letter from BT arrived at my address in Cambridge advising someone who does not live, and has never lived, at my address that her directory details were being amended. I had not been a BT customer for over 20 years, so I was puzzled and telephoned BT, to no avail, before returning the letter to them with a note asking them to check their customer's address etc. However, a couple of weeks later a similar letter addressed to the same person arrived. Once again I returned the envelope to BT. Shortly before Christmas 2011 a telephone bill arrived, addressed to the same person. Opening it I was able to get the customer's telephone number from the bill. I telephoned her to ask if she was expecting a bill from BT and to to find out the correct address to send it to. It transpired that she lives in Lanarkshire, Scotland. In the course of our 'wee blether', I mentioned that my sister lives in Scotland, having moved from England many years ago, and is currently living in a tiny village of around 200 people just north of Perth. My new friend said she new the village as a friend she had known for many years, since they were guides together, also lives in the village. And the coincidence? - my sister knows my new friend's old friend very well as they live just four doors apart in a close of eight properties!
