But you are assuming that voice telepathy is real.

Long-distance communication: Another 2014 study conducted by psychiatrist Carles Grau and his colleagues found that brain-to-brain communication via the Internet is possible. In my book, “Tinker Dabble Doodle Try: Unlock the Power of the Unfocused Mind” I describe an experiment in which they proved that a person thinking of the words "hola" or "ciao" in India could communicate this to people in Spain without saying it out loud, being seen, or typing it. Information can, in fact, be transmitted across large distances when the Internet is the highway that connects the two people.

Instead of "ciao," which is sort of obvious, perhaps they should have tried thinking "Tutankhamen."

The sample sizes in these studies are very small, and the findings have not been well-replicated. The ability to duplicate findings is a far more complex issue than we can deal with in this blog, but suffice it to say that many scientists do not believe that replication of any such finding is statistically feasible.

I mean, okay, if two people are very familiar with each other, they could very possibly predict what the other one is thinking or is about to say, based on the circumstances, not on anything else. If results cannot be duplicated, is it still science?

My daughter, for example. She has a knack for knowing what's going on in my head. It does not require telepathy. Just being observant, paying attention to what's going on at the moment, plus familiarity with the other person, is enough.

I chuckled about the part on schizophrenia. Just because someone claims he is "hearing voices" does not make it so.

Thank you for your information and opinion @Albert Manfredi.
