What is positivity bias?
Positivity bias, also known as the “Pollyanna Principle,” is a beneficial form of bias that influences how individuals perceive their own lives and interpret past events. Named after Pollyanna, the excessively cheerful orphan girl from Eleanor H. Porter’s 1913 novel, this principle highlights a widespread tendency across cultures and individuals to focus on positive information while downplaying negative words. This bias operates on both the conscious and subconscious levels.
Positivity bias helps individuals emphasize positive words and remember pleasant items, leading to a generally optimistic outlook on the future. Although the Pollyanna hypothesis suggests that this bias can sometimes result in unrealistic expectations, it generally contributes to increased happiness, better health, and improved social connections. People tend to maintain a more favorable view of their circumstances despite adversity by focusing on positive elements and minimizing negative aspects.
