While this approach has some heuristic value, if the disease falls in the C category and is not pursued adequately, it will minimize the … Y1 - 1999/1/1. In this particular heuristic, individuals first use an anchor, or some ball park estimate that surfaces initially, and adjusts their estimates until a satisfactory answer is reached.

Anchoring is the fact that people tend to cling on to the first piece of information (or anchor) they encounter, and let their subsequent actions, such as estimates, arguments, and conclusions, be made in relation to it. The key point about the anchoring heuristic is that different starting points yield different estimates, which are biased towards the initial value or number. The heuristic maintains that anchoring bias is caused by insufficient adjustment because final judgements are assimilated toward the starting point of a judge's deliberations. ...
