In psychology, this type of cognitive bias is known as the anchoring bias or anchoring effect, which often sways decisions and occurs regardless of gender and other external factors. Even arbitrary numbers can lead participants to make incorrect estimates. In one example, participants spun a wheel to select a number between 0 and 100. The volunteers were then asked to adjust that number up or down to indicate how many African countries are in the U.N. Those who spun a high number gave higher estimates than those who spun a low number. In each case, the participant used that initial number as the anchor point for their decision. Anchoring Bias Can Influence How Much You're Willing to Pay Imagine you're buying a new car. You read online that its average price is $27,000. At the local car lot, the dealer offers you the same vehicle for $26,500, which you quickly accept, After all, you might reason, it's $500 less than what you were expecting to pay—but the dealer across town is offering the same vehicle for just $24,000, a full $2,500 less than what you paid and $3,000 less than the average price you found online. If you buy the more expensive car, you might berate yourself for making such a quick decision without shopping around. So why might you jump so quickly on that first offer? Because your initial research indicated that $27,000 was the average price—your anchor point. Despite further information, such as the possibility that other dealers might have lower prices, you based your decision on that anchor. Any price lower than that probably would have been appealing. The anchoring bias suggests that we favor the first bit of information we learn. Pixabay Anchoring Bias Can Influence How Much You Make Imagine that you're negotiating a pay raise with your boss. You might hesitate to make an initial offer, but anchoring-bias research suggests that the first person to lay their cards on the table might have the advantage. So you name a number, which then becomes the anchor—the starting point for all further negotiations. This puts negotiations in your favor because your first offer established a range of acceptable counteroffers. Any future offers will use that initial number as an anchor or focal point. Even irrelevant or incorrect details can serve as anchors. This makes media literacy—the ability to evaluate what you see and read accurately—crucial in contemporary life. Anchoring Bias Affects Much More Than Your Finances The anchoring effect has an impact on many areas beyond financial and purchasing decisions. Take these examples: How old should your kids be before you allow them to date? Your kid argues that their peers are dating at 14, but you were raised to believe that 16 is the minimum dating age. Thus, 16 is your anchor, and any other age will be relative to that.How long do you expect to live? If your parents were both very long-lived, you might automatically expect to live a long life. Because of this anchoring point, you might ignore the fact that your parents lived a healthier, more active lifestyle than yours.How much television should your children watch each day? If you watched lots of TV as a kid, a few hours might seem acceptable.What is causing a patient's chronic pain? The anchoring effect can influence a physician's ability to diagnose an illness because their first impression of symptoms can become an anchor point that affects all subsequent assessments. How the Primary Effect Works Nora Carol Photography/Getty Images Awareness Is Key The next time you're making an important decision, consider the possible impact of the anchoring bias on your choices. Are you giving enough weight to all of the available information and possible options, or are you basing your decision on an existing anchor point? 10 Cognitive Biases That Impact Thinking 6 Sources Verywell Mind uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
