Given your last "physicist" claimed to have done double slit experiments in which he recorded data from the detectors, got a non-intereference pattern, deleted the data, and the pattern magically changed to an intereference pattern....(This is highly suspect because a), its never been reproduced, b) data is actually not recorded in a double slit experiement, and c) the guy is a con just trying to sell his books)
I bothered to read the paper, and I see a few problems. First, the test is not double blind, the researches who analyze the EEG's (which is already subjective) have knowledge of the experiment conducted, thus provide bias on the data. Second, the two "observers" are in adjacent rooms that are not sound proofed, the second observer would be able to hear the first observers movement and breathing. Third, the experiment has never been repeated (at least according to the paper). Forth, all other quantum experimentation proves the opposite.
