Reading at night shortens your life. Video games provoke mass murder. Soda makes people aggressive. What?! No! Every day the media writes about sensational discoveries and shocking research results. But not all of them can be trusted: statistical errors, deliberate falsifications and unobvious flaws have not been canceled. Due to the COVID-19 pandemic, humanity was forced to take a crash course in statistics: now we are well versed in graphs, have heard something about the normal distribution and are familiar with the survivor's mistake. But we still have a lot to learn: How do mathematical models work? What is the difference between absolute and relative risks? What do the ratings say? What is the Texas shooter's mistake? Science journalist Tom Chivers and economics lecturer at Durham University David Chivers show how to avoid being fooled by numbers using examples of high-profile headlines during Covid-19 times.
