As I have said multiple times before, that specific question is incredibly stupid as too many people in the West have been browbeaten into giving the "correct" answer or declining to participate. Measuring racism requires the eye test and more subtle intuition, not ham-fisted polls.
On nearly all objective measures, the "West" is overall significantly less racist than it was - I know this as well when comparing things now to how they were even in my 1980s youth. Of course some people hide their racism better than others - when was that not true of any prejudice ever?
Tbh this looks rather like invoking pseudo-science to deny obvious reality.
