Depends what you mean by “reading minds.” If we’re talking about constant broadcasting of everything everyone thinks, then you’ve got an information overload that would be like living in the midst of very loud static all the time. I think not.
If I could selectively tune into a small part of someone’s mind—not necessarily the speech center, then I might consider it. But as it is, I would argue that I, and all of us, already do read minds. We have become extraordinarily sensitive to many different cues that people give off as to what they think.
Of course, some of us are better than others. That’s a matter of experience and training and skill, combined with a lack of handicaps. I think people with social anxiety disorder have a harder time reading minds than most people. So do those on the autism spectrum.
If you could actually dig into a person’s mind and somehow intercept thoughts as they happened, would you get any more truth than you get now? I’m not at all sure that you would. Minds are actually made up of many different parts, and they don’t all agree, and you might catch one thought that doesn’t actually end up being the consensus output of that person’s brain. Then where would you be?
