Stop Bashing Free Will!":
When people doubt free will, they are more likely to behave badly. After reading a passage from a book that challenged the validity of free will, students were more likely to cheat on a mathematics exam.

There would be no point in even describing it as highly ethical behaviour.
Horgan wants to be a materialist atheist but still have free will, as if such a position were even possible.
One can understand a non-materialist atheist assuming free will, of course, but then the non-materialist does not claim to have a theory by which the movement of elementary particles accounts for everything.
