Anchoring, Activation, and the Construction of Values

Area of Science:

• Cognitive Psychology
• Behavioral Economics
• Decision Science

Background:

• Anchoring is a widespread judgment bias where decision-makers are influenced by arbitrary starting points.
• This bias affects various judgments, including knowledge recall, financial valuation, and social perceptions.
• Recent research explores the underlying cognitive mechanisms driving anchoring effects.

Purpose of the Study:

• To investigate the cognitive processes underlying the anchoring bias.
• To test the hypothesis that anchoring operates through feature activation and construction.
• To identify potential debiasing strategies for anchoring effects.

Main Methods:

• Five experiments were conducted to examine anchoring effects.
• Manipulations focused on prompting participants to consider features of the target item.
• Measures included judgments of value and belief, alongside cognitive process assessments.

Main Results:

• Prompting consideration of features *different* from the anchor significantly reduced anchoring.
• Encouraging focus on features *similar* to the anchor did not influence the bias.
• Cognitive measures supported the anchoring-as-activation hypothesis.

Conclusions:

• Anchoring may occur by increasing the accessibility of shared features and decreasing the accessibility of distinct features.
• Considering dissimilar attributes offers a mechanism for debiasing anchoring.
• The anchoring-as-activation model may explain other judgment phenomena.
