When the listened music matched the expected music in the brain, the positive and negative signals cancel each other out.
A former aerospace engineer turned YouTuber Rick Cavellero designed a land yacht that harnesses the power of the wind to propel itself faster than said wind. After online disagreements with physics professors, one who bet him $10,000 that it wasn't possible according to the laws of perpetual motion, he built the real thing and won the bet!
The Atlantic published an interesting article about how considering the opposite viewpoint when making a decision can lead to better decision making.
