The Spacing Effect: The Science Behind Why Cramming Doesn't Work The night before an exam, students around the world engage in the same ritual: cramming. They review notes for hours, filling their short-term memory with facts and formulas. Many pass the test. But ask them the same questions a week later, and most of the knowledge has evaporated. The spacing effect, one of the most reliable and well-replicated findings in all of psychology, explains exactly why this happens and what to do instead.

After more than 130 years of research, the spacing effect remains one of the strongest and most practically important findings in the science of learning. For readers who invest significant time in books and want to actually retain what they learn, understanding the spacing effect isn't optional. It's the foundation upon which effective learning is built. What Is the Spacing Effect? The spacing effect (also called the distributed practice effect) is the finding that memory is stronger when study sessions are...
