Denial of fact
In this form of denial, someone avoids a fact by utilizing deception. This lying can take the form of an outright falsehood (commission), leaving out certain details to tailor a story (omission), or by falsely agreeing to something (assent). Someone who is in denial of fact is typically using lies to avoid facts they think may be painful to themselves or others.
Denial of responsibility
This form of denial involves avoiding personal responsibility by:
blaming: a direct statement shifting culpability and may overlap with denial of fact
minimizing: an attempt to make the effects or results of an action appear to be less harmful than they may actually be
justifying: when someone takes a choice and attempts to make that choice appear acceptable due to their perception of what is right in a situation
regression: when someone acts in a way unbecoming of their age
Someone using denial of responsibility is usually attempting to avoid potential harm or pain by shifting attention away from themselves.
Denial of impact
Denial of impact involves a person’s avoiding thinking about or understanding the harms of his or her behavior has caused to self or others, i.e. denial of consequences. Doing this enables that person to avoid feeling a sense of guilt and it can prevent him or her from developing remorse or empathy for others. Denial of impact reduces or eliminates a sense of pain or harm from poor decisions.
