Anchoring is the behavioral pattern where the first piece of information we receive about a situation is what all other data points are compared to. For example, the price of the first menu item we see at dinner, the degree of physical pain experienced when exercising, or perceived positivity or negativity in an interaction with a person -- whatever our first experience of these contexts might be, we're likely to view all information received afterward as being either worse or better than those initial impressions.
When I’ve read about anchoring, its been discussed as a cognitive bias, and it appears to be viewed as a huge blind spot in human reasoning. But if this is such a strong tendency, it must serve us in some contexts (or have served us at one point in time).
So, does anchoring ever improves our judgement, instead of deprecating it?
