Ray Dalio has practiced meditation since 1968.

True: biographical sources (Dalio's own book Principles, the David Lynch Foundation, or reliable profiles) show he began practising meditation (Transcendental Meditation) in 1968 and has continued to practise it up to 2020. Mostly true: the start date was 1968 or 1969 (e.g. sources differ by one year), or there were short breaks, with practice continuing. Mostly false: he began meditating several years later than 1968, or stopped for a long period. False: reliable sources show he did not begin until well after 1968, or does not practise meditation.

   “So in 1968, he became a daily practitioner of Transcendental Meditation — a discipline he has continued to find helpful throughout his life.”

4. E4 Our Founder Bridgewater Associates Own record

   “In 1969, he learned the practice of Transcendental Meditation, to which he attributes much of his success.”

Entrepreneur (E1) and a Transcendental Meditation organisation's article (E3) both put the start of Dalio's meditation practice in 1968. Bridgewater's founder page (E4) says he learned Transcendental Meditation in 1969, so the sources disagree by one year. E2 and E3 say he kept up the practice over the following decades. The resolution criteria treat a one-year difference between sources, with practice continuing, as mostly true.
