Peter Gamma from www.petergamma.org mentioned two projects which eventually could be secret projects, for whatever reasons:
The secret meditation research projects of Mind Monitor developer James Clutterbuck & his wife at the University of Toronto in Canada:
And the one of Lars at Laghsam Zurich which is eventually funded by companies such as for instance Roche Pharma Basel:
But secret meditation research projects with only one or two persons do not make much sense. These only would make sense with a statistically relevant group of people, as for instance all the teachers and eventually some students of Lagham Tibetan Meditation in Zurich.
