Time series analysis indicated that during three assemblies of approximately 7000 experts in the TM Sidhi Programme (the square root of one per cent of the world’s population at that time), there was a significant increase in the World Index of international stock prices, indicating improved confidence in the world economy. During control periods at the same time of year in the five years prior to these assemblies, there was no significant change in the World Index.Ref.‘Time series impact assessment analysis of reduced international conflict and terrorism: Effects of large assemblies of participants in the Transcendental Meditation and TM-Sidhi program’. Paper presented at the American Political Science Association Annual Meeting, Atlanta, Georgia, August 1989

During periods when the size of a group of participants in the TM Sidhi Programme in the USA exceeded the square root of one per cent of the national populations of the USA and Canada together, there was a significant improvement in a comprehensive quality of life index comprising behavioural variables (reduction in the total of homicides, suicides, motor vehicle fatalities, and cigarette consumption), controlling for changes in national economic trends, such as unemployment.Ref.Proceedings of the Social Statistics Section of the American Statistical Association (Alexandria, Virginia: American Statistical Association): 38–43, 1996

Quality of life in Israel improved significantly, as measured by an index comprising decreased crime, increased Tel Aviv Stock Exchange index, and improved national mood (analysis of daily news), when a large group was participating in the TM Sidhi Programme in Jerusalem.Ref.Journal of Conflict Resolution 32: 776–812, 1988

Quality of life was measured by improvement in a comprehensive index that includes crime, auto accidents, motor vehicle fatalities, deaths due to other causes, alcoholic beverage consumption, cigarette consumption, unemployment, and pollution.Ref.The Journal of Mind and Behavior  8: 67–104, 1987
