This episode looks at terms connected to making assumptions, starting with the often-cited origin of the phrase "when you assume, you make an ass out of u/you and me". The word bias originally referred to a diagonal line, while projection comes from roots meaning to throw forward. Occam’s Razor is a principle that favours the simplest explanation, and Simpson’s Paradox highlights how data can be misleading. The episode also examines how mistaken assumptions about animals gave rise to expressions like 'seeing red' and 'wise as an owl'.
