Psychology & social science
People are the instrument and the subject, so design and ethics matter more here than anywhere.
What counts as evidence: Behavioral or survey data collected under a pre-registered design, or careful synthesis of existing studies.
- Use a validated scale where one exists rather than writing your own questions.
- Decide your sample and analysis before collecting — no fishing afterward.
- Get informed consent, and parental consent for participants under 18.
- Keep responses anonymous and store them somewhere locked.
