Allport's Scale of Prejudice and Discrimination is a measure of the manifestation of prejudice in a society.
It was devised by psychologist Gordon Allport in 1954.
[1][2] Allport's Scale of Prejudice goes from 1 to 5.
This scale should not be confused with the Religious Orientation Scale of Allport and Ross (1967), which is a measure of the maturity of an individual's religious conviction.
