But you have to be able to have a control. I heard Barbara Sakitt speak around 1976-77. She was the author of the widely cited "Counting Every Quantum" (1972) and she basically said that her original methodology was flawed. Unfortunately, no one cites her later work and I don't have access to the full text of "Information received from unseen lights" (1976) which I think was the paper she was presenting.
