"How We Learn" - Summary
"How We Learn" by Benedict Carey is a groundbreaking exploration of the science behind learning. This book challenges conventional wisdom about how the brain absorbs and retains information, offering powerful and often counter-intuitive insights. Through engaging stories and practical tips, Carey reveals the secrets to unlocking our full potential in various aspects of life, from academics to sports. Whether you're a student, a professional, or simply someone eager to improve your memory and learning skills, "How We Learn" provides valuable strategies that are both accessible and effective. It's a must-read for anyone looking to enhance their cognitive abilities and achieve their goals.
Key Ideas
The Importance of Forgetting
One of the central ideas in "How We Learn" is that forgetting is a crucial part of the learning process. Carey explains that our brains are designed to forget irrelevant information, which helps us focus on what truly matters. This selective memory process enhances our ability to retain important knowledge and skills over time.
The Role of Sleep in Learning
Carey delves into the science of sleep and its impact on learning. He highlights how different stages of sleep contribute to memory consolidation and problem-solving. By understanding the connection between sleep and learning, readers can optimize their rest patterns to improve cognitive performance and retention.
The Power of Testing and Self-Assessment
Another key idea presented in the book is the effectiveness of testing and self-assessment as learning tools. Carey argues that frequent testing, even self-quizzing, helps reinforce knowledge and identify gaps in understanding. This approach not only boosts memory but also builds confidence and mastery over the subject matter.

Forgetting is often seen as a failure or an enemy of learning. However, research in cognitive science and brain biology reveals that forgetting is actually a powerful ally in the learning process. Forgetting serves as a sophisticated spam filter, allowing the brain to focus on relevant information and enabling sought-after facts to come to mind more easily. This filtering process helps block background noise and distractions, allowing the right signals to stand out.
One of the key principles in understanding the power of forgetting is the distinction between storage strength and retrieval strength. Storage strength refers to how well something is learned, while retrieval strength measures how easily a piece of information can be accessed. Both strengths increase with studying and use, but retrieval strength drops off quickly without reinforcement.
The Forget to Learn theory posits that some forgetting is necessary for subsequent learning to occur. This passive decay of retrieval strength allows for deeper learning when the material is revisited, similar to how muscle breakdown during exercise leads to increased strength afterward. This process is known as desirable difficulty, where the harder we have to work to retrieve a memory, the greater the subsequent spike in retrieval and storage strength.
An example of this theory in action is the study conducted by psychologist Philip Ballard, where students were asked to memorize a poem. The first test not only measured their memory of the poem but also increased the storage and retrieval strengths of the verses they remembered. When tested again two days later, most students performed better on the second test, demonstrating the power of forgetting in enhancing learning.
In conclusion, forgetting is not a failure or an obstacle to learning but rather a crucial component that enables deeper understanding and retention of subject matter. Embracing the power of forgetting can lead to more effective learning strategies and better long-term retention of information.
