Anchoring is where an individual relies too heavily on an initial piece of information offered (considered to be the “anchor”) when making decisions. This could be a previous research document or something someone said earlier that day. When this bias is in effect, the type of anchor is less relevant than the fact there’s an anchor in place to begin with.
A useful counter-measure is to write a quick list of the main thoughts one is having at any certain time, and place them in order of what they consider to be of importance. Then ask, are they justified to be in that order?
