I agree with this assessment.Siggy_G wrote: We [can't] access other minds, because that would require access to the exact same EM signals and in the exact same structural manner as they are distributed within their brain.
By way of analogy, you might say that a radio is just as connected to all of the radio signals moving through the air as it is to the one that is playing on the radio at the moment. So why is it that only one station plays at a time?
First, the radio is tuned to one station.
Second, sometimes more than one station does play--and the result is a garbled noise that can be hard to make sense of.
In the same way, I believe people 'tune' in to their own particular "frequency". But just as the radio can pull in more than one signal, so can the human mind. ESP, and other paranormal phenomena may be just that. And although the Hollywood version of this almost certainly doesn't exist--there is a fairly convincing body of evidence that suggests that people can 'tune' into things they shouldn't be able to. Statistically, the numbers are quite significant--although even the best still seem to get things wrong more often than they get them right.
Another possibility is that some forms of mental illness may be caused (in part) by tuning in to unusual 'frequencies'... and the person's inability to deal with what they perceive.
