On Saturday I described the anti-Brexit march in London as "a metric shit tonne of people" and "a pretty big protest".
I made sure to hedge my bets that day as I know just how contentious the politics of crowd size can be. You perhaps wouldn't think something as simple as how many people were at a thing would be up of debate but this is just another one of the issues with our stupid monkey brains, we're really bad at intuitively working out large numbers.
Which is why "the million" that matched on Sunday was actually somewhere around 312 000 - 400 000.
