Percentage of RWU (black bars) versus PC (white bars) students who believe one of the following statements describes them best: A = I accept evolution and express it openly regardless of others’ opinions, B = no opinion, C = I accept evolution but do not discuss it openly to avoid conflicts with friends and family, D = I believe in creationism and express it openly regardless of others’ opinions, E = I believe in creationism but do not discuss it openly to avoid conflicts with friends and family.
