Psychologist Adam Estriani discusses the issue of forgetting what we learn in formal education. Studies show that a significant portion of knowledge is lost over time. Even the speaker, who graduated college less than 10 years ago, struggles to remember all the classes taken. The argument that learning to think is more important than memorizing facts is challenged, as the focus in classrooms is often on transmitting facts rather than teaching critical thinking. Traditional learning methods like highlighting and cramming are proven ineffective. The disconnect between what we aim to achieve in education and the results is a prevalent issue.
