The Taxonomy

Five tiers, one red line

Not all influence is attack, and a framework that cannot tell the difference protects no one. The taxonomy classifies cognitive and information operations across five tiers — from activity states have always conducted, to conduct history has already judged criminal — precisely enough for legal application, plainly enough for policy use.

Working Draft

Status. What follows is the working structure prepared for the First Psychosecurity Summit, published for orientation and comment. The summit amends and adopts; nothing here is final. Definitional detail, classification rules, and the questions reserved for the room are deliberately not reproduced.

01 · Dimensions

How operations are classified

The taxonomy assesses an operation along five dimensions, and assigns it to the highest tier whose defining criteria it meets:

Target

Population at large → defined group → named individual.

Intent

Inform → persuade → deceive → destabilise → decompose.

Transparency

Overt and attributable → deniable → covert.

Coordination

Isolated act → sustained campaign.

AI enablement

None → augmenting human operators → autonomous and adaptive.

Target and intent do most of the classificatory work; transparency and coordination generally aggravate rather than define; AI enablement is the scaling condition that makes the framework urgent, not the boundary of the offence.

02 · The Five Tiers

From public diplomacy to the red line

TierCategoryDefining criteriaAssessment
IPublic diplomacy & strategic communicationsOvert, attributable. Target: populations. Intent: inform, persuade.Legal and expected. Conducted by all states, including democracies.
IICovert influence operationsDeniable or falsely attributed messaging. Target: populations. Intent: persuade or deceive.Ethically contested. Governed by existing norms and domestic law.
IIIComputational amplificationBot networks, synthetic personas, manufactured consensus. Target: populations. Intent: deception at scale.Ethically contested; increasingly regulated (EU DSA and analogues). Still mass influence.
IVTargeted cognitive operations against individualsCoordinated harassment, doxxing, intimidation, reputation attack against named individuals — short of systematic decomposition.Presumptively unlawful under domestic law. The contested borderland.
VPsychological decomposition operations (AI-driven Zersetzung)Systematic campaign against a named individual or defined group, with intent to decompose psychological integrity, relationships, reputation, or sense of reality.The red line. Prohibited. When widespread or systematic, a potential crime against humanity.

The tiers are cumulative in seriousness but not in method: a Tier V operation may use every technique of the tiers below it. What moves conduct across the red line is the combination the Declaration's draft criteria describe — target (individual civilians, not populations), intent (decomposition, not persuasion), systematicity (campaign, not incident), and method (capabilities achieving precision, scale, or deniability beyond unaided human operators).

Tier IV deserves a note: it is the borderland where much present-day harm actually lives — pile-ons, doxxing, coordinated reputation attack. The taxonomy neither excuses it nor inflates it; it names it as presumptively unlawful under existing domestic frameworks, while reserving Tier V for the systematic decomposition that international law is needed to reach.

03 · The Graduated Scale

Ethics redlines: a 1–10 scale of operational acceptability

Alongside the taxonomy of operations, the framework carries a graduated scale of methods — a 1-to-10 ladder from routine to unequivocally prohibited. It serves two functions at once: an internal safeguard for institutions that conduct legitimate influence activity, and a yardstick for assessing adversary conduct.

LevelsBandCharacter
1–3RoutineOvert, truthful, attributable communications; strategic emphasis; overt persuasion using behavioural insight, directed at populations. Standard practice with doctrinal safeguards.
4–6ContestedOperations raising serious ethical questions — deniability, deception, targeting refinements. Require senior oversight and explicit authorisation pathways.
7–10ProhibitedMethods crossing ethical redlines, culminating in systematic psychological decomposition. No authorisation pathway exists at any level of seniority.

The level-by-level definitions, worked examples, and boundary cases are part of the summit's working papers and will be published with the adopted framework.

04 · What Happens Next

From draft to doctrine

The taxonomy and scale above are two of the six elements of the Psychosecurity Framework, alongside escalation thresholds, an attribution framework, industry accountability pathways, and the capstone Declaration. Strawman drafts of all six go before the First Psychosecurity Summit for amendment and adoption; the adopted texts will be published here for wider endorsement.
