Cambridge Coincidences Collection
Professor David Spiegelhalter of Cambridge University wants to know about your coincidences!
Why? By recording your coincidence stories here, you can help him build a picture of what kinds of coincidences are out there and which ones seem to ‘get to’ us the most. Your coincidence stories can also help him explore the scientific explanations which may account for them – whether by doing the maths to calculate the chances of a coincidence, or speculating on the weird and wonderful workings of our brains.
Coincidences tend to be ‘surprising matches’ – sometimes they are lucky, sometimes unlucky, sometimes just mind-boggling. To help you recall the coincidences that have happened in your life, here’s a list of some common types of coincidence:
- Surprising repetitions: for instance when you’ve had not contact with someone for ages, then find two connections to them very close together in time. Or when over several years multiple members of the same family are born with the same birthday. Or even a repetition of a really rare event – like winning the lottery twice, or your life being saved twice by the same person!
- Simultaneous events: for example when two people phone each other at exactly the same time.
- Parallel lives: such as when two people in a small group find they share a birthday or an unusual name, or when two people discover their lives match each other in bizarre details.
- Uncanny patterns: imagine picking letters in Scrabble that spell your name.
- Unlikely chains of events: perhaps you lost your false teeth overboard and found them inside a fish you caught twenty years later?
If anything coincidental has happened to you - anything that made you stop and say "well, what were the chances of that..?" - then please record your story in the form below! Please try to keep your story personal - about you or someone you know. The only thing we'd ask you to steer clear of are premonitions or déjà vu, purely because - whilst fascinating - they're quite common and also difficult to analyse.
You could also tell us about coincidences in the news, but please provide a link to a reliable source!
Title: two or three words that give a simple description of your story, eg ‘old friend’ or ‘birthday coincidence’
Coincidence: tell your coincidence story - and please include plenty of relevant detail (places, dates, numbers etc.) and include your first name if you want.
