Don, I discussed the Asian/BP issue yesterday in posts timed 5.36 and 6.04 AM.

I had assumed wrongly that you had worked out the culture thing.
Sorry.
Here is the reasoning. Feel free to correct it.

Those five people all attributed the behaviour to aspects of the culture.
So prominent are they that their opinions were universally reported by all the media, including all the quality broadsheets and national broadcasters.
No detractors have been similarly reported and no other theory has been reported at all.

Was I in any way wrong to assume that all within that culture would be exposed to those aspects of the culture?

If it caused the behaviour in some, as claimed, I would expect the distribution of effects to be a continuum from actual offending down to zero inclination.
Agree?
We know that the spectrum is skewed towards non offending as only a minute minority offend.

That is my assumption but social psychology is not my field.
I am open to correction.
