In the article "Using 100% of Your Brain" by Dr. Bruce H. Lipton, the author explores the misconception that humans only use a small percentage of their brain. Dr. Lipton explains that this belief is not true, as our brains are always active and their full potential is utilized. He states that this misconception likely stems from a misinterpretation of scientific research. The author encourages individuals to embrace the idea that we already use our brains to their maximum capacity and focus on tapping into our innate potential.
