Psychological Tricks
Psychological Tricks represent a meta-category of dark patterns formally classified under “Cognitive Manipulation” and “Deception.” Rather than relying on technical coercion or outright lies, these interfaces weaponize innate human cognitive biases—such as the framing effect, anchoring, and decision fatigue—to steer users toward suboptimal, business-favorable outcomes. By designing the choice architecture to exploit systemic flaws in human heuristics, the system circumvents deliberative economic evaluation. The interface preconfigures the choice architecture, ensuring that the user's intuitive, “System 1” thinking acts directly against their own best interests by prioritizing immediate cognitive ease over long-term utility.

Asymmetric Dominance
Condition 1: Asymmetric Dominance
Given
To identify the manipulation of relative perception, we define as the provider's preferred tier and as a lower-cost alternative. We introduce , a third option engineered strictly to alter the choice matrix. The feature triggers if the decoy is designed to be inferior to the target option in every metric while remaining structurally similar in price. This artificially inflates the target's perceived value, mathematically shifting the user's preference probability toward the more expensive, yet seemingly more "valuable" option:

Cognitive Overload
Condition 2: Cognitive Overload
Given
The hostility of an interface is often measurable by the exhaustion it induces in the user. We define as a sequence of complex configuration choices and as the psychological threshold for decision fatigue. Let be the pre-selected default state that serves the provider's extraction goals. The feature triggers if the interface inflates the cardinality and complexity of the matrix beyond human cognitive stamina, statistically guaranteeing that the exhausted user will abandon active evaluation and surrender to the hostile default:

Reference Point Obfuscation
Condition 3: Reference Point Obfuscation
Given
A fundamental indicator of cognitive contamination is the use of arbitrary anchors to inflate perceived value. We define as the intended selling price and as an inflated numerical value (e.g., a fabricated “MSRP”) positioned with high visual salience. The feature triggers if the interface forces the user to process the inflated anchor first, contaminating their Willingness To Pay () threshold. This makes the baseline cost appear as a compelling discount regardless of its actual market value:
