Recently, I have been reading Plagues of the Mind by Bruce Thornton, about which I will say more shortly, on the epidemic of false knowledge that surrounds us these days.
False knowledge is what we know that ain’t really so. And often common sense will help us see why it can’t be so. Here’s one example: We are told that the human and chimp genomes are 99.5% similar.
You heard that? Now forget it. Here is a more realistic summary, with explanation, offering a figure in the 70 per cent range – a figure you can believe is reasonable.
I use this example because no one has much difficulty figuring out the difference between a human and a chimpanzee, and if the 99.5% folk were right, it should be difficult. Otherwise, the only conclusion I can draw is that the genome is not as important a source of information as we once supposed.
This, by the way, has nothing whatever to do with controversies over common ancestry of humans and chimps. In theory, we have a common ancestor with silverfish too, but if you hear that your genome is 97.5% similar to that of a silverfish, you should suppose that some pretty important information is stored somewhere other than the genome.
Incidentally, if it were true that the human and chimpanzee genomes were 99.5 percent similar, that would shoot genetic determinism dead in the water. Just sayin’ is all …
In short, common sense is our best defense against epidemics of false knowledge blowing through the pop science media.
That said, in response to my skepticism about new mind reading techniques, someone wrote to assure me that, at the pace of current progress, there is no doubt we will soon use machines to read minds. (my reply below) Read More ›
