A strong element of prejudice is cognitive bias: the prejudiced person falls into a number of traps in thinking ranging from basic cognitive lacunae involving memory and perception to more complex errors in thinking such as overgeneralisation and subjective validation (this means seeing truths and connections where there may be none). However, critical thinking goes further than cognition alone: different theories point to a broad repertoire of attitudes, emotions and developmental patterns that can all be considered in the educational response to prejudice.
