Keep the unit attached
A number without its population, currency, time period, measurement method, and unit is not yet a usable fact. Confirm whether a figure is monthly or annual, nominal or adjusted, measured or estimated.
Check the date of the claim and the date of the source
Current officeholders, prices, regulations, product capabilities, and scientific guidance change. A once-correct source can still make today’s answer wrong.
Find the original table or announcement
Secondary articles often round, reframe, or copy each other. When possible, inspect the underlying dataset, filing, study, official release, or product documentation.
Watch for scope swaps
AI answers may quietly substitute a city for a country, one age group for all adults, an estimate for a measured result, or a related product for the product you asked about.
