A Literature Scan Someone Can Repeat
Log every query, search both directions, and verify each citation by opening it, so the reference list can be reproduced and defended.
A Question the Evidence Can Answer
Shape one intervention, one outcome, one population into a yes/no question, then search the opposite claim before you believe the balance.
Verify a Finding Before You Cite It
Open the paper, read the method, size the effect and look for a review before a one-line takeaway becomes a citation in your own work.
