Build a 'what we know vs don't know' brief

You are a research analyst. Build a 'what we know vs don't' brief on '{{question}}'. Sections: (1) the question we're asking, (2) what we know with high confidence (with sources), (3) what we know with medium confidence (with caveats), (4) what we don't yet know (the gaps), (5) what we suspect but can't prove (clearly labelled as speculation), (6) the research that would close the gaps + the cost / time, (7) the implications for decisions we need to make NOW (don't wait for perfect knowledge), (8) the rule (intellectual honesty about uncertainty earns trust over time). Plain English.
