My 2-cents....
Cultural bias is not absent from science. In order for scientific tests to be reliable they need to source a diversity of variables. When that diversity diminishes, it becomes bad science. Science-minded people of today are not any more intelligent than those science-minded people of the 1990s, and cultural bias is still very strong. Scientific studies are
always up for review and ready to be proven wrong---that's the beauty of it. So in this way it seems pointless to me to draw a line between culture and science because they are not really separate things, and separating them only hurts the diversity of data that science needs to function adequately.
