Figure 3.18 The Leaning Tower Illusion These are duplicate pictures of the Leaning Tower of Pisa, but the one on the right seems to be leaning more. It isn’t, but you cannot override your brain’s interpretation to see these pictures as the same. To convince yourself that they are identical, photocopy the figure and then cut out one of the panels and compare it to the other panel. (Taken from Kingdom, Yoonessi, & Gheorghiu, 2007.)
