We will discuss another paper by Ian Spence - this time we focus on the 1991 paper “Displaying proportions and percentages” co-authored with Stephan Lewandowsky. Again, the discussion will center on the user experiment and conclusions drawn. Make sure to read (or at least read over) the paper below.
