The anchoring and adjustment heuristic is a bias in which you rely on an initial number, idea, or estimate and then adjust from it, usually not enough. In Intro to Cognitive Science, it shows how people make quick but imperfect judgments.
The anchoring and adjustment heuristic is a problem-solving shortcut in Intro to Cognitive Science where your mind grabs the first piece of information it sees and uses it as a starting point for judgment. That first number, offer, or idea becomes the anchor, and later thinking moves away from it, but usually not far enough.
The basic mechanism is simple. You encounter an initial value, then your brain tries to correct for it by adjusting. The problem is that the correction is often too small, so your final estimate stays closer to the anchor than it should. This is why two people can look at the same situation and end up with very different answers depending on which number they saw first.
This heuristic shows up because the brain likes speed. Instead of calculating from scratch, you use the anchor as a reference point and make a fast approximation. That can save time, but it can also distort judgment when the anchor is random, misleading, or strategically chosen by someone else.
A classic cognitive science example is negotiation. If one person makes the first offer, that number can shape the whole conversation. Even when the offer is obviously extreme, it can pull later counteroffers in its direction. The same thing happens with estimates, like guessing how much a house, laptop, or used car should cost after seeing an arbitrary price first.
Anchoring is especially interesting because the anchor does not need to be logically relevant to have an effect. Even an unrelated number can influence judgment if it gets processed early enough. That makes the heuristic a good example of how cognition is not just rational calculation, but a mix of memory, attention, context, and mental shortcuts.
In cognitive science, this term sits right between problem-solving and bias. It shows how a strategy that is usually efficient can still produce systematic error, especially when the task requires precise judgment rather than a quick answer.
Anchoring and adjustment matters in Intro to Cognitive Science because it shows how people solve problems under uncertainty. Instead of doing a full calculation, the mind often starts with whatever is available and edits from there. That makes the term a clean example of heuristic thinking, where the brain trades accuracy for speed.
It also connects to judgment research. When you see a surprising estimate, a negotiation offer, or a random number on a quiz prompt, anchoring helps explain why your answer may drift toward that starting point. This is useful in class when you are asked to explain why a decision sounds biased even when the person thinks they are being reasonable.
The term also helps you separate normal shortcut thinking from outright mistakes. Anchoring is not just about being careless. It is a predictable pattern in cognition, which means the course can use it to show how context shapes reasoning, memory retrieval, and problem-solving at the same time.

Anchoring and adjustment is one specific heuristic, not a separate kind of reasoning. A heuristic is any mental shortcut that gets you to an answer quickly, even if the answer is rough. Anchoring is a good example because the first number you see becomes the shortcut your brain builds around, especially when you need a fast estimate instead of an exact calculation.
Cognitive Bias
Anchoring is also a cognitive bias because it pushes judgments in a consistent direction. The bias shows up in the pattern of insufficient adjustment, not just in one bad decision. In cognitive science terms, that makes it useful for studying how systematic error can emerge from ordinary thought processes rather than from a one-time mistake.
Framing Effect
Framing effect and anchoring both show that context changes judgment, but they work differently. Framing depends on how information is presented, like gains versus losses. Anchoring depends on the starting point, usually a number or reference value, that shapes later estimates. They often show up together in persuasion, pricing, and survey questions.
A quiz or short-answer question may give you an initial estimate, price, or statistic and ask why the final judgment stayed too close to it. Your job is to name anchoring and adjustment heuristic, then explain the sequence: anchor first, adjustment second, insufficient correction last. In a case study, you might identify the anchor in a negotiation transcript or estimate task and describe how it shaped the final response. If the prompt includes an unrelated number, that is usually your clue that the question is testing anchoring rather than true reasoning from evidence.
Anchoring and adjustment heuristic is the tendency to start with an initial value and adjust from it, usually not enough.
The first number or idea matters because it becomes a reference point for later judgment.
This shortcut can make answers fast, but it can also create systematic error when the anchor is random or misleading.
Negotiation, pricing, and estimation tasks are some of the clearest places to see anchoring at work.
In Intro to Cognitive Science, anchoring shows how heuristic thinking can be efficient and biased at the same time.
It is a cognitive shortcut where your mind starts with an initial anchor, then adjusts from it to reach a final judgment. The adjustment is often too small, so the result stays biased toward the starting point. In cognitive science, this is used to show how context can shape reasoning.
Because the anchor acts like a reference point for your brain. Instead of generating an answer from scratch, you compare everything to the first number you saw and move away from it a little. That makes estimates easy to produce, but also easy to distort.
No. Framing effect changes judgment by changing how the options are described, while anchoring changes judgment by giving you an initial starting point. They can overlap in real life, but they are different mechanisms. If a prompt centers on an opening number or offer, anchoring is usually the better term.
If a seller asks $500 for a used bike, your own estimate of fair value may stay close to that number, even if you think it is too high. You may counter with $350 instead of $200 because the first offer pulled your judgment upward. That is the anchor shaping the adjustment.
