Why Does the Insurance Adjuster Sound So Friendly on the Phone?
Warmth is the cheapest tool available to anyone whose job is to pay you less, which is why it is never in short supply. The call is friendly because of: 1) reciprocity of disclosure, a warm voice pulls details out of you that no form ever would 2) the halo effect, once he seems decent you stop reading what he sends as carefully 3) anchoring, the first offer exists to reset what you believe the claim was ever worth. Nice is not the opposite of adversarial. Sometimes it is the method.
