Some sociologists also argue that, particularly in the West, where racism is often negatively sanctioned in society, racism has changed from being a blatant to a more covert expression of racial prejudice. The "newer" (more hidden and less easily detectable) forms of racism – which can be considered embedded in social processes and structures – are more difficult to explore as well as challenge. It has been suggested that, while in many countries overt or explicit racism has become increasingly taboo, even among those who display egalitarian explicit attitudes, an implicit or aversive racism is still maintained subconsciously.
