‘Any feedback?’ gives the reader a large, undefined task. They may comment on punctuation when you need to know whether the argument makes sense.
Specify the review: ‘Could you check whether the opening explains the problem clearly for a first-time reader? I’m not looking for line edits yet.’ This gives the reviewer a useful lens and prevents work on details that may soon change.
Explain the stage of the work when it affects the request. A rough outline invites structural feedback. A final document may need factual verification and a check for missing information.
If there are several questions, identify the most important one. ‘My main concern is whether the example supports the conclusion’ helps the reviewer allocate attention.
Avoid framing the request so that only praise feels acceptable. ‘Looks good, right?’ makes disagreement socially harder than a question that genuinely invites assessment.
Also give the person enough time and context to respond. A clear question cannot compensate for an unavailable document or a deadline that has already passed.
Before requesting feedback, finish this sentence: ‘The answer will help me decide whether to…’ If you cannot complete it, narrow the request until the reviewer can tell what their response is meant to improve.
