Confirmation bias can lead us to ignore signs that a relationship is unhealthy or has no future, by pushing us to focus only on evidence that supports the hope that the relationship will improve.

The concept of confirmation bias, widely documented in cognitive psychology, accurately describes our tendency to favor information that confirms our pre-existing beliefs while dismissing contradictory evidence (Nickerson, 1998, literature review). This mechanism is well-studied in the context of interpersonal relationships where emotional investment is high, reinforcing the difficulty of objectively perceiving a toxic dynamic. Dr. Smith's explanation is scientifically grounded in its basic principles, as the brain does indeed seek to reduce cognitive dissonance to maintain a form of internal consistency. While the 'plastic plant' analogy is a simplified clinical metaphor, it correctly illustrates the phenomenon of maintaining expectations despite repeated contrary evidence. There is no notable exaggeration here, as the author explicitly states that confirmation bias is one factor among others and advises against any impulsive decision, which demonstrates a cautious and balanced approach.
