Figure 1. An ambiguous figure. Created by the author based on a figure by Roger Shepard in Mind Sights (W.H. Freeman and Company, 1990). The figure, sometimes seen as a series of arrows pointing to the left and other times as a series of arrows pointing to the right, provides a striking example of the importance of an appreciation of intrinsic variability for the understanding of behavior (see text).
