evaluation of problems. As a result of this, earlier studies hypothesized that people with more depressed moods would tend to use anchoring less than those with happier moods. However, more recent studies have shown the opposite effect: sad people are more likely to use anchoring than people with happy or neutral mood. In a study focusing on medical practitioners, it was found that physicians that possess positive moods are less susceptible to anchoring bias, when compared to physicians with neutral moods. This was specifically found to be because a positive mood leads to information processing that is more systematic which leads to more efficient problem solving. This leads to a decreased anchoring effect. Experience Early research found that experts (those with high knowledge, experience, or expertise in some field) were more resistant to the anchoring effect. However, anchoring happens unconsciously which means that unless someone who is knowledgeable is warned prior, they are still susceptible to anchoring. Since then, however, numerous studies have demonstrated that while experience can sometimes reduce the effect, even experts are susceptible to anchoring. In a study concerning the effects of anchoring on judicial decisions, researchers found that even experienced legal professionals were affected by anchoring. This remained true even when the anchors provided were arbitrary and unrelated to the case in question. Also, this relates to goal setting, where more experienced individuals will set goals based on their past experiences which consequently affects end results in negotiations. Expertise is when a judge has relevant knowledge. In a study using price estimation of cars, it was found that relevant knowledge positively influenced anchoring. Expertise in cognitive bias is related to experience however the two are not exclusively exhaustive. In a study using stock return estimates, it was found that expertise decreases behavioural bias significantly. It was found that other factors like cognitive ability and experience where there is no susceptibility to anchoring or a susceptibility as it increases, tend to become factors that decrease the effects of anchoring when they are an expert. Personality Research has correlated susceptibility to anchoring with most of the Big Five personality traits. The personality traits are as follows. Conscientiousness, a character that is orderly and responsible. Neuroticism, an individual that has an uneasy nature and is unstable. Extraversion which is where a person is sociable and outgoing in nature. Openness to experience which is an intelligent and creative personality trait.
