The Evidence-Based Question is the second free-response question on the redesigned AP Psychology exam. You get summaries of three research sources and a prompt, and your job is to make a defensible claim and back it with evidence from the sources — connected by actual psychological reasoning. Think of it as a mini-DBQ for psychology.
What Earns Points on the EBQ
- A defensible claim that answers the prompt — specific enough to be supported, not a restatement of the question.
- Evidence from at least two different sources — a specific finding, statistic, or design detail from each. Naming the source ("Source B found that…") keeps you organized and makes the reader's job easy.
- Reasoning that connects each piece of evidence to your claim — the "because" sentence that explains WHY the finding supports your position, using a correctly applied psychology concept.
The Mistakes That Cost the Most Points
- Evidence without connection. Quoting a source and moving on earns the evidence point at best. The reasoning point requires you to explicitly link it: "this supports my claim because…"
- Vague evidence. "Source A supports this" is not evidence. "Source A's participants who studied in spaced sessions recalled 30% more items" is.
- Concept misapplication. Dropping in a vocabulary term that doesn't fit costs credibility — a correctly applied everyday explanation beats a misused technical one.
- Ignoring a source that complicates your claim. The strongest responses acknowledge and handle it; a claim can be defensible without pretending the third source doesn't exist.
A Simple EBQ Structure That Works
One sentence of claim. Then for each of two sources: one sentence of specific evidence, one sentence of reasoning tying it to the claim with a psych concept. Five to seven sentences total can earn full credit — the EBQ rewards precision, not length.
How to Practice
AimFive grades EBQ responses on exactly these criteria — claim, source evidence, and reasoning — with published calibration data. The fastest improvement loop is write → see which point you missed → rewrite the same response to earn it.
