For some, the concept seems too “woo-woo” — rooted in superstition rather than fact or science. But Doty, an actual brain scientist, insists there is something scientific to back it up.

If you have an intention, you take a pencil, you write it down. You're actually doing something physical, tactile. Then you read it silently. Then you read it aloud. Then you visualize that and you do that over and over and over again. What that will do is then embed that into your subconscious and then these different cognitive brain networks get activated.
