These events are described in his books Programming and Metaprogramming in the Human Biocomputer: Theory and Experiments and The Center of the Cyclone, both published in 1972.

Experiments have repeatedly found that people tend to test hypotheses in a one-sided way, by searching for evidence consistent with the hypothesis they hold at a given time.

Experiments testing Bell-type inequalities in situations analogous to EPR's thought experiments have been consistent with the predictions of quantum mechanics, suggesting that local hidden variables theories can be ruled out.

Experiments with the moss Physcomitrella patens, however, have shown that choice of the gelling agent — agar or Gelrite-does influence phytohormone sensitivity of the plant cell culture.
