Abstract: Anchoring effects refers to a phenomenon that an irrelative anchor biases a subsequent numerical judgment under uncertain circumstances. The influencing factors and intervention measures vary considerably according to different types of anchoring effects. For example, traditional anchoring effect is affected by the characteristics of anchor information, ability variables, emotional factors and individual differences. The basic anchoring effect is affected by expertise and time pressure. The self-generated anchoring effect is affected by motivation variables, cognitive factors and internal beliefs. Future studies could focus on exploring cognitive processing mechanism, the process of analogical reasoning and DDS system in order to help reduce the anchoring bias.

Key words: anchoring effects, traditional anchoring effect, basic anchoring effect, self-generated anchoring effect
