Diana Baumrind was a clinical and developmental psychologist known for two major things: her research on parenting styles and her critique on the state of deception in research in the field of psychology. Initially, she had theorized three major styles of parenting: Authoritarian, Permissive, and Authoritative.
Each style was characterized by how responsive a parent would be to their children with Authoritarian being very hard, Permissive being very soft, and Authoritative being just the “correct” amount.
