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.
