Evaluating biological claims and communicating uncertainty
≈ 48 minEvaluating biological claims and communicating uncertainty
A scientific claim needs appropriate evidence, a clear link between evidence and reasoning, and honest limits. Check the source, method, sample, comparison and whether correlation is being mistaken for causation. Communicate results with labels, units, a conclusion tied to data and a limitation. Uncertainty is not weakness: stating what evidence cannot yet show makes a conclusion more trustworthy.
