Maharishi Mahesh Yogi explained that when a sufficient proportion of a population, currently defined as the square root of 1%, practices advanced meditation techniques, a "Super Radiance" effect is created that damps down conflict. Currently six nations in Latin America have reached this threshold (see section on Latin America). Several articles have appeared in peer-reviewed journals, though their findings are by no means generally accepted. However, there has been growing interest on the part of military leaders around the world. In addition, personal experience and a large number of studies show improvements in various capabilities (e.g., reaction time, ability to focus, management of stress) that affect police and military personnel functioning.
