Two years ago, I wrote an article about pupillometry, or the measurement of a person’s pupils to infer their cognitive state. Joel Pearson, a psychologist and neuroscientist at the University of New South Wales, was trying to use pupils as a biomarker to assess aphantasia, a condition thought to affect about 3.9% of people.
A quick at-home test for aphantasia, I learned, was called the red star or red apple test. Close your eyes and picture a red apple. How well can you see the apple visually on a scale of 1 to 5, with 1 being the most vivid? Can you see its color, shape and the length of the stem? Is it a bit hazy, coming in and out of focus?

It’s just a metaphor.’ Then, I asked some friends. Not everyone was a 1, but most could see between 1 and 4.
