Sometimes people hold a core belief that is very strong. ~Frantz Fanon (author of The Wretched of the Earth) on Cognitive Dissonance
Tina Miller, MA,CFLE stashed this in quotes
“Sometimes people hold a core belief that is very strong. When they arepresented with evidence that works against that belief, the newevidence cannot be accepted. It would create a feeling that isextremely uncomfortable, called cognitive dissonance. And because itis so important to protect the core belief, they will rationalize,ignore and even deny anything that doesn't fit in with the core belief.”― Frantz Fanon, Black Skin, White Masks
Belief is a powerful thing.
