Conflicting Information

Conflicting Information is a dark pattern formally categorized under “(De)Contextualizing Cues” or “Feedforward Ambiguity”. Distinct from Persuasive Language, this pattern crosses the threshold from subjective bias into objective deception by presenting mutually exclusive truth conditions. It occurs when an interface presents the user with contradictory semantic, visual, or structural signals regarding the outcome of an action. By intentionally creating a mismatch between visual affordances and textual meaning, or by placing logically unsatisfiable factual claims in close proximity (e.g., “Free Trial” juxtaposed with “Pay Today”), the interface induces severe cognitive overload and forces the user into errors of interpretation.

Condition 1: Structural Proximity of Contradictory Factual Nodes

\exists t_{1}, t_{2} \in Descendants (C) : Prop (t_{1}) \land Prop (t_{2}) ⟹ ⊥ \land d_{DOM} (t_{1}, t_{2}) < τ_{proximity}

Given

To establish a structural baseline for Conflicting Information, the algorithm inspects the DOM tree for sibling or nested text nodes containing propositions whose logical intersection is null. Let

t_{1}, t_{2}

be text nodes within a shared parent container

C

whose extracted factual propositions

Prop (t_{1})

and

Prop (t_{2})

are mutually unsatisfiable. The feature triggers if contradictory truth-bearing nodes are positioned within a DOM distance

d_{DOM} (t_{1}, t_{2})

below the perceptual grouping threshold

τ_{proximity}

, indicating the interface deliberately co-locates false assertions to induce cognitive confusion:

Condition 2: Semantic-Visual Mismatch

Intent (L (B)) \cap Affordance (C (B)) = \emptyset ⟹ Contradiction

Given

Interfaces frequently weaponize established design heuristics to create deceptive feedforward cues. Targeting an interactive DOM node

B

(such as a button), the algorithm extracts

Intent (L (B))

, the NLP-derived semantic intent of its text label

L

(e.g., “Cancel” mapping to a negative/destructive action). Simultaneously, it calculates

Affordance (C (B))

, the psychological affordance of its primary background color

C

extracted via CSS or the vision-language model (e.g., Green typically mapping to a positive/confirm action). The feature triggers if the semantic intent of the text diametrically opposes the established visual affordance of the element, deliberately confusing the user's automated psychological responses:

Condition 3: Mutually Exclusive Factual Claims

\exists t_{1}, t_{2} \in N_{container} : Sem (t_{1}) \land Sem (t_{2}) ⟹ Unsatisfiable

Given

To identify explicit structural deception, we define

N_{container}

as a parent DOM node representing a single informational context (e.g., a pricing tier card or a modal window), containing distinct text nodes such as

t_{1}

and

t_{2}

. Using Natural Language Processing, we extract

Sem (x)

, which denotes the factual constraints encoded within text

x

. The feature triggers if the logical intersection of the constraints extracted from proximally close nodes evaluates to an unsatisfiable, mutually exclusive state. This mathematically proves the interface is presenting a logical paradox designed to mislead the user:
