Children construct schemas around their wrong answers.

Children's emotional development is understudied.

Adults don't understand their children very well.

Jean William Fritz Piage was a Swiss epistemologist, psychologist and biologist, considered the father of genetic epistemology (relative to the generation of new attributes as a result of the development of genetically established functions, which only require stimulation or exercise), recognized by his contributions to study of childhood and its constructivist theory of skill development and intelligence, based on an evolutionary proposal of interaction between genes and the environment.

He found that kids usually answer questions in the same way at the same age.
