What is anchoring bias?

Anchoring bias is the tendency to rely too heavily on the first piece of information you receive. Once an anchor number is in mind, your estimates drift toward it even when the anchor is arbitrary and unrelated to the real answer.

What is the framing effect?

The framing effect is when the way a choice is worded changes your decision, even though the options are identical. People tend to avoid risk when an outcome is framed as a gain and take risks when the same outcome is framed as a loss.

Are cognitive biases on the AP Psychology exam?

Yes. Heuristics and biases — including anchoring, the framing effect, the availability heuristic, and the representativeness heuristic that drives the conjunction fallacy — are part of AP Psychology Unit 2 (Cognition). You should be able to define each and recognize it in a scenario.

Cognitive Bias Test

Your brain runs on shortcuts. Three quick tasks below catch anchoring, framing, and the conjunction fallacy in your own thinking — the heuristics and biases AP Psychology asks you to recognize. Answer honestly before each reveal.

Can you outsmart your own brain?

Three short questions. There are no "right" answers — just answer naturally, and we'll show you the shortcut behind each one.

What Is a Cognitive Bias?

A cognitive bias is a systematic shortcut in thinking that leads to predictable errors. Most come from heuristics — fast mental rules of thumb that usually save time and usually work, but misfire in specific situations. The three tasks above each target one of these shortcuts so you can feel it from the inside instead of just reading a definition.

The Three Biases You Just Tested

Anchoring bias is over-relying on the first number you hear. The "100" (or "12") in Task 1 was arbitrary, yet it likely tugged your estimate toward it. The real answer is 54.

The framing effect is letting wording change your choice when the options are actually identical. In Task 2, a "gain" frame ("200 will be saved") pushes most people toward the safe option, while a "loss" frame ("400 will die") pushes the same people toward the gamble — even though the outcomes are the same.

The conjunction fallacy is judging a specific combination as more likely than one of its parts. In Task 3, "bank teller and feminist" can never be more probable than "bank teller" alone, because it's a subset — but the vivid description makes the combination feel more representative. That pull is the representativeness heuristic.

Heuristics and Biases in AP Psychology (Unit 2)

Heuristics and the biases they create are squarely in AP Psychology Unit 2: Cognition. For the exam, be ready to define and identify anchoring, the framing effect, the availability heuristic, and the representativeness heuristic — and to explain that heuristics are useful shortcuts that sometimes produce errors. This is also the bridge to behavioral economics, the Kahneman-and-Tversky territory behind the tasks above.
