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.

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.
Anchoring and adjustment theory in economics is where people's decision-making and outcome are affected by their initial reference point. The reference point for a consumer is usually the status quo. Status quo bias results in the default option to be better understood by consumers compared to alternatives options.
The Cognitive Bias Codex. A cognitive bias is a systematic pattern of deviation from norm or rationality in judgment. [1] Individuals create their own "subjective reality" from their perception of the input. An individual's construction of reality, not the objective input, may dictate their behavior in the world.
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 anchoring bias, or focalism, is the tendency to rely too heavily—to "anchor"—on one trait or piece of information when making decisions (usually the first piece of information acquired on that subject). [11] [12] Anchoring bias includes or involves the following:
People display an impact bias when they overestimate the intensity and durability of affect when making predictions about their emotional responses. It is a cognitive bias that has been found in populations ranging from college students (e.g. Dunn, Wilson, & Gilbert, 2003; Buehler & McFarland, 2001), to sports fans (Wilson et al, 2000), to ...
