I think we're all likely to suffer some degree of self-deception and I've occasionally seen it in myself but deep down my rational self keeps telling me such thinking is bunkum and I'm left with no option other than to change my view. From experience self-deception is different to being wrong about things. I'm often factually wrong about matters and whilst I'm often surprised to learn about it I'm always thankful that I've been corrected. The question remains why do many of us find self-deception worrying whilst others are quite happy to live with it.
