There are several research studies in psychology that explore how our decisions and behaviors are influenced by the people around us. We might think we are independent and make our own individual decisions, but the research says we are more influenced by other people than we realize.

One principle from psychology that I saw at work in my own life the other day is called the ‘anchoring and adjustment heuristic.’ This principle says that when making judgments or decisions, we tend to look at what someone else does and use that as a starting point—then we adjust a little bit higher or lower.

This can get us in trouble if the person we use as a starting point is way off base.

This happened to me the other day. I was meeting up with some friends for dinner at a barbecue restaurant. At this particular restaurant, you just walk up to the front and tell the cook what kind of meat you want, as well as how much. My friend went first and ordered a pound of brisket and half a pound of ribs. I used his order as my starting point and adjusted down a bit—I ordered half a pound of brisket and half a pound of ribs.

I still ended up ordering way too much food.

This was a pretty silly example with no real consequences (except for a stomachache). However, it’s good to be aware of the anchoring and adjustment heuristic, because it can have important consequences on your life. For example, if you are in a negotiation and offer one price, it is likely that the other side will base their counter-offer on your starting position. If the other side begins by giving an offer, it is likely that you will base your counter-offer on their starting position.

Discussion: How have you seen the anchoring and adjustment heuristic at work in your life? In what ways could you use this principle to your advantage?
