How often do you tell white lies? When the "New York Times" ran an article linking children's lying with their cognitive abilities (Stone, 2018), the authors decided to examine this phenomenon through the lens of Montessori philosophy. Consequently, the authors delved into the related research on lying, executive function, and prosocial behavior and followed up with interviews of Montessori educators, who added a personal view on how to address children's lying in a Montessori environment.
