Decision-Making and Judgment Biases

The Pollyanna principle, also called Pollyannaism or positivity bias, is the tendency for people to remember pleasant items more accurately than unpleasant ones. Research suggests that at a subconscious level the mind tends to focus on the optimistic, while at the conscious level it more often focuses on the negative.
