  The validity of the assertion that some recent double-slit interference
experiments, conducted by Radin et al., would have tested the possible role of
the experimenter's mind in the collapse of the quantum wave function, is
questioned. It is emphasized that quantum mechanics doesn't need any
psychophysical ingredient to explain the measurement processes, and therefore
parapsychologists shouldn't resort to the latter to support the possibility of
psychokinesis, but search for more convincing explanations.
