Over the last few years a number of books, notably Sabine Hossenfelder's Lost in Math , David Orrell's Economyths , Cathy O Neil's Weapons of Math Destruction and Tim Palmer's The Primacy of Doubt , have pointed out problems with the mathematical modelling done by businesses, physicists, meteorologists, epidemiologists, economists and more. These are not anti-science polemics, but rather people who know what they're talking about pointing out the dangers of getting too carried away with elegant mathematics and models, often assuming that the models effectively are reality (and certainly presenting them that way in some of the writing and press releases from the scientists building and using the models). Erica Thompson takes on the problems of mentally inhabiting the mathematical world she describes as 'model land'. As she cogently points out, it's fine to play in model land all that you like - the problem comes with the way that you exit model land a...
