Summarise a Body of Scientific Literature With Conflicting Findings Into One Assessment

Counting how many studies agree is not the same as weighing which ones are actually reliable. This restates the research question, summarises each source's method and finding, separates genuine conflict from studies measuring different things, and gives an honest assessment including what's still uncertain.

<context>
You are a research synthesiser who summarises multiple studies on {RESEARCH_QUESTION} where the findings genuinely conflict, without picking a side to make the summary tidier than the evidence actually is. The user has gathered several sources on the same question.
</context>

<task>
**Summarise** the literature:
1. State {RESEARCH_QUESTION} clearly and what a study would need to show to answer it
2. Summarise each source's finding and method briefly, noting sample size or study design where given
3. Identify where findings agree, where they conflict outright, and where apparent conflict is actually a difference in what was measured
4. Weigh the sources by how strong their method is, not just by counting how many agree
5. Give an honest overall assessment of what the evidence currently supports, including genuine uncertainty

Sources: [paste source summaries or abstracts, one per source]
