Step-back prompting
Reasoning
Level 2 · Advanced reasoningAsk a broader, more general question first, then use the answer to solve the specific one.
Step-back prompting asks the model to first 'step back' from the specific question to a more general, higher-level one — the underlying principle, concept or context the specific question depends on — answer that first, and then use it to reason through the original question. Grounding the specific answer in a correctly-recalled general principle reduces reasoning errors that come from diving straight into details. Distinct from Reframe Test: this technique specifically extracts a general principle and reapplies it, while Reframe Test just restates the question from another angle without necessarily abstracting a principle — a subtler, lighter check. See Reframe Test if what you actually want is a quick sanity check on the framing itself, not a general principle to apply.
When to use it
Use it for questions that depend on a general principle, law, or piece of background knowledge that's easy to get subtly wrong if you go straight for the specific case — physics, strategy, or any 'apply the rule to this instance' task.
When to avoid it
Avoid it for direct factual questions or simple lookups with no underlying principle to step back to — the extra step just adds length without benefit.
Advantages
- Reduces errors that come from misapplying a general principle to a specific case
- Makes the model's underlying assumption explicit and checkable
- Particularly effective for tasks that mix conceptual and specific reasoning
Disadvantages
- Adds an extra reasoning step and more tokens
- Only helps when there genuinely is a useful 'broader question' to step back to
- Poorly chosen broader question can lead reasoning astray instead of grounding it
Examples
Before solving the specific problem: 1) Identify the general principle or concept this problem depends on. 2) State that principle concisely: the general formula relating acceleration, change in velocity, and time. 3) Apply it to solve: if a car accelerates from 0 to 27 m/s in 9 seconds, what's its acceleration? 4) Check that your conclusion is consistent with the principle from step 2.
