Tversky and Kahneman [75] suggest that the anchoring effect is the product of anchoring and adjustment heuristics whereby estimates are made starting from an anchor value which is then adjusted in until the individual has reached an answer. Kahneman suggests that anchoring occurs from derivations from anchor-consistent knowledge.
Anchoring and adjustment is a heuristic used in many situations where people estimate a number. [78] According to Tversky and Kahneman's original description, it involves starting from a readily available number—the "anchor"—and shifting either up or down to reach an answer that seems plausible. [78]
Adjustment, on the other hand, is the process through which individuals make gradual changes to their initial judgements or conclusions. Anchoring and adjustment has been observed in a wide range of decision-making contexts, including financial decision-making, consumer behavior, and negotiation. Researchers have identified a number of ...
The spotlight effect is an extension of several psychological phenomena. Among these is the phenomenon known as anchoring and adjustment, which suggests that individuals will use their own internal feelings of anxiety and the accompanying self-representation as an anchor, then insufficiently correct for the fact that others are less privy to those feelings than they are themselves.
It is one of the earliest economic theories that explicitly acknowledge the notion of cognitive bias, though the model itself accounts for only a few, including loss aversion, anchoring and adjustment bias, endowment effect, and perhaps others. No mention is made in formal prospect theory of cognitive bias mitigation, and there is no evidence ...
The representativeness heuristic is simply described as assessing similarity of objects and organizing them based around the category prototype (e.g., like goes with like, and causes and effects should resemble each other). [2] This heuristic is used because it is an easy computation. [4]
To say that anchoring is the bias is to confuse the cause and effect, and not how these things are written about in the sources. In the Gilovich, Griffin, Kahneman edited volume "Heuristics and Biases: the Psychology of Intuitive Judgement", the entry in the index is for "anchoring and adjustment heuristic".
anchoring and adjustment heuristic (the inclination to overweight the importance and influence of an initial piece of information, and then adjusting one's answer away from this anchor). [ 18 ]
