The classic study by Wimmer and Perner showed that children below the age of about 4 years of age fail to appreciate others' false beliefs. This opened the floodgates to the theory-of-mind research programme. Recently, a study by Riggs and Simpson has called the central challenge of false belief into question, reporting similar difficulties with true belief. I would argue, however, that not only should the acquisition of false belief remain a central concern but that we should think harder about it and its earlier manifestations.
