Claim	C011

Claim: The Wardle and Derakhshan Information Disorder Taxonomy classifies information failure along two dimensions — falseness of content and intent to harm — producing three categories: misinformation, disinformation, and malinformation.

BLUF: The claim is accurate. Wardle and Derakhshan's 2017 Council of Europe report defines the three categories along exactly these two dimensions. The framework is widely cited and adopted.

Probability: Almost certain (95-99%) | Confidence: High
