Why might the anchoring and adjustment heuristic lead us to make errors in estimation?

The anchoring and adjustment heuristic can lead to errors in estimation because individuals often rely too heavily on an initial piece of information (the anchor) when making decisions. This initial anchor can skew their judgment, causing them to insufficiently adjust their estimates even when additional relevant information is available. Consequently, their final estimates may remain close to the anchor, leading to systematic biases and inaccuracies in their evaluations. This bias is particularly pronounced when individuals are not aware of the influence of the anchor on their thinking.
