If one of my horses, "finished" or not, "puts 2 hooves up" when I asked it something, I wouldnt treat it like a horse who understood what I asked. because understanding what is asked INCLUDES understanding that they have to do it without protest
we are talking of what 99.99% of the horse world will agree
using the fact that it is "commonplace" is just silly. From the michael polanyi quote I gave, i'd guess 99.99% of people at some point genuinely believed in witchcraft. People used to be willing to burn other people alive because they were so
sure that witches were real. Willing to kill over it. That was still happening only 300 years ago, and not much can happen evolutionarily to the capabilities of any creatures brain in the space of 300 years, especially one as complex as the human brain. So don't assume we're much more capable of reason than they were. But what happened was: someone scientifically minded came along and objectively questioned the anecdotal or testimonial evidence that convinced the people of the time that witches were real, and there was and still is no scientifically verifiable explanation (a bit like here) presented in defence of that. And we've learned from that process.
Why is this any different to that? Either way: a question was asked, there's been plenty of testimonies, people willing to stand up for what they believe to be true (which is entirely respectable), plenty of specific examples given and plenty of experience drawn from, but no objective answer.
