C011 — Wardle and Derakhshan Information Disorder Taxonomy¶
Research: R0052 Run: 2026-03-31 Mode: claim
BLUF¶
The claim is very likely correct but requires minor qualification on the dimensional language. Wardle and Derakhshan's 2017 taxonomy classifies information disorder using the dimensions of falseness and intent to harm, producing three categories: misinformation (false, no intent to harm), disinformation (false, intent to harm), and malinformation (true, intent to harm). However, the original report uses "falseness" and "harm" as distinguishing characteristics rather than formal "axes" or "dimensions" in a strict mathematical sense.
Probability / Answer¶
Rating: Very likely (80-95%) Confidence: High Rationale: The three categories and their distinguishing characteristics are confirmed by the original Council of Europe report and multiple secondary sources. The characterization as "two dimensions" is a common and accurate summary of the framework, though the original report's presentation is more typological than strictly dimensional.
Reasoning Chain¶
- Wardle and Derakhshan published "Information Disorder: Toward an Interdisciplinary Framework for Research and Policymaking" (2017) for the Council of Europe. [Source: SRC01, High, High]
- The report defines three categories: misinformation, disinformation, and malinformation, distinguished by falseness of content and intent to harm. [Source: SRC01, High, High]
- Misinformation = false content, no intent to harm. Disinformation = false content, intent to harm. Malinformation = true content, intent to harm. [Source: SRC02, High, High]
- The Profolus analysis notes the framework uses "intentionality of harm" and "accuracy of content" as distinguishing characteristics rather than strict formal axes. [Source: SRC03, Medium, High]
- JUDGMENT: The claim accurately describes the taxonomy's core structure. The "two dimensions" framing is a widely used and reasonable summary, though the original presentation is more classificatory than axiomatic.
Hypotheses¶
H1: The claim is substantially correct¶
Status: Supported Evidence for: Three categories confirmed. Falseness and intent to harm are the distinguishing characteristics. Evidence against: Minor: the original report doesn't use the word "dimensions" formally.
H2: The claim is substantially incorrect¶
Status: Eliminated Evidence for: None. Evidence against: All sources confirm the three categories and their basis in falseness and harm.
H3: The taxonomy exists but the dimensional framing is an oversimplification¶
Status: Supported (as nuance) Evidence for: The original framework is typological (three discrete categories) rather than truly dimensional (continuous axes). The Profolus analysis notes they aren't presented as "simple X-Y axes." Evidence against: The falseness/harm distinction is used to generate the categories, which is functionally equivalent to a two-dimensional classification.
Evidence Summary¶
| Source | Description | Reliability | Relevance | Key Finding |
|---|---|---|---|---|
| SRC01 | Council of Europe report page | High | High | Official publication details |
| SRC02 | Profolus framework analysis | Medium | High | Detailed analysis of dimensions |
| SRC03 | Multiple academic references | High | Medium | Confirm three categories and their basis |
Collection Synthesis¶
| Dimension | Assessment |
|---|---|
| Evidence quality | Robust — original Council of Europe report plus academic analyses |
| Source agreement | High — all sources agree on the three categories and their basis |
| Source independence | Independent — official publication, academic analyses, teaching materials |
| Outliers | None |
Gaps¶
| Missing Evidence | Impact on Assessment |
|---|---|
| Full text of original Council of Europe report | Would confirm exact language used for the dimensional distinction |
Researcher Bias Check¶
Declared biases: The researcher's methodology references information disorder as a threat model. Influence assessment: Low risk — factual description of a published taxonomy.
Revisit Triggers¶
| Trigger | Type | Check |
|---|---|---|
| Wardle or Derakhshan revise their taxonomy | data | Monitor their publications |
| Council of Europe updates its information disorder framework | policy | Check Council of Europe media publications |
| Academic critique challenges the dimensional framing | data | Search for "Wardle Derakhshan" + "critique" |
