Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'информированный консенсус' – this is a calque and sounds unnatural. The standard term is 'информированное согласие'.
- Do not confuse with simple 'разрешение' (permission) or 'одобрение' (approval), as 'informed consent' carries a specific legal/ethical weight.
Common Mistakes
- Using it for trivial permissions (e.g., 'I gave informed consent for my friend to borrow my pen').
- Omitting 'informed' when the specific term is required in technical contexts (e.g., 'We need consent' vs. 'We need *informed* consent').
- Using as a verb (e.g., 'He informed consented' is incorrect).

Key elements typically include disclosure of information, comprehension by the subject, voluntariness of the decision, competence of the subject, and formal agreement (often documented).
Yes. While originating in medicine, it is now standard in psychological research, social science studies, data privacy regulations (like GDPR), and any context where a person's autonomous agreement based on understanding is ethically or legally required.
