I mean, answering your question seems to be exactly the point of the book.

If one were take you as genuinely curious about how people might convince themselves of a belief that seems entirely alien and implausible to you, the next step would probably be to earnestly read the book with the credit of good faith in its authors.

I think we can take for granted that doing so would not persuade you of very much, but it might inform you, so that you're no longer so "mind blown".
