From time to time I'd like to go back and review some of the earlier stuff we covered, and today we looked back at patterns in coin-tossing in the wider context of how difficult it is for people to process statistical concepts. We watched the TED talk of renowned statistician Pete Donnelly where he used this example to introduce further instances of people misinterpreting uncertainty. Part of his talk was dedicated to a famous case in the UK where a witness at a trial completely misunderstood simple probability, and nobody in the jury had the tools to question his statements - a woman ended up in jail for many years before it was pointed out that the mathematics at the trial were completely flawed. Pete Donnelly also touched on false positives, and this is a topic we shall cover in more depth next week.
