Claims. Evidence. Framing.
Decide for yourself.
The Assertion independently examines claims that are often presented as facts—in health, public policy, media, science and current affairs.
How we examine a claim
04
Notice the Nudge
Examine how language, framing and omitted context may steer the reader.
01
The Assertion
Identify the precise claim being made.
02
The Evidence
Trace the claim to its sources and examine what the evidence actually shows.
03
The Limits
Set out weaknesses, assumptions and questions the evidence cannot answer.
05
What Remains Unknown
Separate what is established from what remains uncertain, disputed or unknown.
