See Cognitive Dissonance.
Self Sabotaging Behavior (AKA: Self-handicapping) is a cognitive strategy used to withdraw efforts or create obstacles in order to keep potential failure from hurting self-esteem, or to maintain public and private self-images of competence.
Individuals have a general tendency to seek consonance between their views of themselves (self-esteem, self-concept, self-efficacy) and their lives. Critical inner voices (negative self-talk) encourage individuals to act out their defenses in all areas of their lives. Individuals are often unaware of their own self-sabotaging thoughts and behaviors.

Confirmation Bias is a tendency to remember, interpret, or selectively search for information that is consistent to one's beliefs. This type of cognitive bias is stronger for deeply rooted or emotionally charged issues. It explains other cognitive phenomena:
- Irrational primacy effect
- focus on information encountered early in series
- also see Experiential Ordering.
- Illusionary correlation
- Illusion-of-truth effect
- tendency to believe a familiar statement than an unfamiliar one
- Attitude polarization
- differing conclusions to same evidence
- Choice-supportive bias
- memory bias that makes past choices seem better than they actually were
- Belief perseverance
- belief persists after belief is shown to be false
