“Enhancing our memory is just the beginning. When you express an idea in writing, it’s not just a matter of transferring the exact contents of your mind into paper or digital form. Writing creates new knowledge that wasn’t there before. Each word you write triggers mental cascades and internal associations, leading to further ideas, all of which can come tumbling out onto the page or screen.V Thinking doesn’t just produce writing; writing also enriches thinking. There is even significant evidence that expressing our thoughts in writing can lead to benefits for our health and well-being.11 One of the most cited psychology papers of the 1990s found that “translating emotional events into words leads to profound social, psychological, and neural changes.” In a wide range of controlled studies, writing about one’s inner experiences led to a drop in visits to the doctor, improved immune systems, and reductions in distress. Students who wrote about emotional topics showed improvements in their grades, professionals who had been laid off found new jobs more quickly, and staff members were absent from work at lower rates. The most amazing thing about these findings is that they didn’t rely on input from others. No one had to read or respond to what these people wrote down—the benefits came just from the act of writing.”
