Do you believe in free will?

[Angrboda]

The constant appeal of those that refuse to address concrete criticism of the philosophy which they feel proves them correct "Neither of us can prove this or that, we're probably both wrong".

That wasn't an appeal of "those that refuse to address concrete criticism" but a well evidenced conclusion from psychological research into cognitive bias. And that's not even what I said. I said that us blaming the other is likely not going to be a case of one being all wrong and one being all right in the matter. But as usual, you're projecting your assumptions on to my words, and equivocating by restating what I said in ways that aren't faithful to what I wrote, these are common forms of cognitive bias (and reasoning mistakes) and if you think your thinking has evaded all bias, that is likely yet another cognitive bias known as the bias blindspot. I'm quite willing to accept that I'm biased and my thinking is probably in some sense irrationally biased and flawed. You apparently think you are not; I guess that makes you a new species. (And you wonder why I question your credibility?)
