Just on a year ago now (almost a birthday!) I posted about the birthday paradox, with a review of general results and then some remarks on erroneous conclusions from DNA matching. In the post there is a subheading called Quadratic Football, referring to the facts that the median of the birthday para ...

The ease at which these groups, free of managerial frameworks, can be formed today is rapidly changing the institutional landscape. In 2006, a woman named Ivanna left her phon ...

The Misperception: If everyone has a say so in a decision making process, everyone will get what they want and be satisfied. The Truth: In large groups of people, the odds any two people will share the same opinions or preferences are good, but the odds of consensus are astronomical. This idea is ea ...

In a group of 23 people, the probability that two or more people will share their birthdays is greater than 50%. For a group of 57 people, this probability increases to 99%. This may seem counter-intuitive at first sight. There are 365 possible days on which a birthday can occur. So it may seem odd ...

In this blog I have mentioned that I am a supporter of the idea of a ‘history of science’ for conservation, by which I mean conservation as a whole and not just the ‘conservation science’ subfield. In part this probably stems from the years I spent working a job in a University Library, particularly ...

Most people have a very poor intuitive grasp of mathematical probability, and this can more often than not lead us to formulate erroneous conclusions regarding how likely some things are to happen. A good example of this is the so-called Birthday Paradox: What do you think is the likelihood of any t ...

This is one theory that really interested me. Can you guess what is the probability that any two people in a football court ,out of a total of 23 including the referee,share the same birthday. It is more than 50 %. Atleast we have mathematical proof for that. The actual statement is “In a group of a ...
