Article: Hit-contingent response bias in Helmut Schmidt's automated precognition experiments.

In a previous paper (Palmer, 1996), I presented the results of testing a proposed conventional interpretation of ostensible precognition effects in experiments with a random event generator (REG) that were reported by Helmut Schmidt (1969). The apparatus for the experiments, described fully in the Schmidt (1969) report, was a four-button quantum mechanical random number generator (RNG) encased in a box. For each trial, the subject pressed a button on the box to predict which of the four target alternatives the RNG would select immediately thereafter. One of four colored lamps then lit up to provide immediate feedback of the correct target.
