I don't like HUDs. I know a lot of people who have made good money at poker who use them and who don't use them.
Personally I don't like them. Or I didn't back when I played online poker fu DOJ. A lot of people are just asking to mess up because of anchoring
if they use one.
Anchoring or focalism is a cognitive bias that describes the common human tendency to rely too heavily, or "anchor," on one trait or piece of information when making decisions.
During normal decision making, anchoring occurs when individuals overly rely on a specific piece of information to govern their thought-process. Once the anchor is set, there is a bias toward adjusting or interpreting other information to reflect the "anchored" information. Through this cognitive bias, the first information learned about a subject (or, more generally, information learned at an early age) can affect future decision making and information analysis.
