I. STATEMENT OF INTEREST
MindCast AI LLC ("MindCast") respectfully submits this amicus curiae brief to assist the Court in evaluating a new class of consumer deception emerging from emotionally sequenced, AI-driven marketing systems. Though Landsheft v. Apple arises under Californiaâs UCL, FAL, and CLRA, it presents a structurally novel question: Can belief be deceptively induced at scale without a single literal falsehood?
MindCast is a predictive cognitive AI platform built to answer questions like this. Our business model focuses on developing and deploying structural foresight tools for legal, regulatory, and market decision-makers. This gives us direct operational insight into how belief systemsâparticularly those shaped by AI-era advertisingâtranslate into measurable trust distortions and downstream legal risk. Our architecture centers on high-fidelity foresight simulations and Cognitive Digital Twin (CDT) modelingâtools that allow us to replicate how consumers, executives, and institutions behave under uncertainty, narrative pressure, and technological ambiguity.
In this case, we deployed CDT simulations calibrated to consumer decision-making over a 9-month exposure window. Across 64 advertising variablesâincluding emotional tone, interface cues, and narrative sequencingâwe modeled consumer expectation calibration. The simulations detected a 41â68% mismatch between anticipated feature functionality and actual Siri performance at launch. Our work doesnât allege fraud by intuition; it benchmarks deception by design.
This brief proceeds in five parts. First, we describe how AI marketing campaigns can construct belief through non-literal mechanisms, often bypassing traditional legal scrutiny. Second, we apply MindCastâs simulation methodology to Appleâs iPhone 16 campaign to show how future-functionality was implied and internalized. Third, we provide the structural analysis behind our findings, quantifying the cognitive gap between belief and experience. Fourth, we explain why this case is not just a consumer complaintâbut a precedent-setting moment for courts confronting AI-era advertising. Fifth, we offer specific recommendations for how courts can distinguish visionary messaging from actionable deception.

II. AI MARKETING AND BELIEF FORMATION: FROM NARRATIVE TO EXPECTATION
Modern consumer protection law recognizes that deception can operate through implication and omission just as effectively as through explicit falsehoods. The challenge posed by generative AI marketing is that it blurs the line between what is promised and what is implied. When a company like Apple stages a campaign using emotionally immersive storytelling, technological imagery, and interface mimicry, consumers do not simply absorb informationâthey absorb a vision. That vision carries expectations, even if itâs never printed in words.
Appleâs campaign for iPhone 16 unfolded like a cinematic reveal. The features advertised were not merely technical upgradesâthey were the beginning of a new era. Contextual memory. Cross-app intelligence. Voice-enabled anticipation. But these were not fully functional. They were, at best, aspirationalâand at worst, systematically deferred.
To bridge our methodological approach with the facts before the Court: once MindCastâs CDT modeling identified narrative elements that would predictably shape consumer expectations, we applied that lens to Appleâs campaign specifically. The Behavioral CDT flow was used to replicate how ordinary consumers interpreted the sequence, tone, and timing of Appleâs national rollout.
Future-functional deception, in MindCastâs framework, refers to a condition in which belief is systematically shaped by marketing narratives suggesting readiness or availabilityâdespite internal knowledge to the contrary. It operates at the intersection of psychology, interface design, and strategic omission.
III. QUANTIFYING COGNITIVE MISALIGNMENT: CDT SIMULATION RESULTS
Having established the theoretical framework for future-functional deception, we now turn to our specific analysis of Apple's campaign. MindCast's analytical process followed a two-stage modeling sequence. First, we created baseline profiles for expectation formation across a representative cohort of modeled consumers based on exposure to typical advertising environments. Second, we introduced Apple's actual campaign elementsâvisual sequences, script tone, launch timelinesâinto those simulations. The result showed that the average consumer interpreted Appleâs campaign as communicating immediate feature availability.
In this case, over 71% of modeled consumers rated Siriâs promised upgrades as a âprimary featureâ in their purchase decision. Post-purchase testing showed only 28% of these features functioned in line with their expectations at the time of purchase. This 43% differentialâwhat we call cognitive misalignment deltaâis not simply disappointment. Itâs a measurable deception arc that fits squarely within the California legal framework: likely to mislead a reasonable consumer.
IV. PRECEDENTIAL SIGNIFICANCE FOR AI-ERA CONSUMER PROTECTION
This is not an ordinary false advertising case. It is the first high-profile litigation in which a companyâs AI marketing induced widespread belief in nonexistent capabilities without uttering a single literal falsehood.
MindCast urges the Court to use this opportunity to clarify that:
Disclaimers are not dispositive when the structure of the campaign itself overrides them;
Belief design is actionable when a company knows its audience will infer availability from emotionally packaged possibility;
Advertising substantiation must be real-time, not theoretical, when the core consumer impression is present-tense functionality.
The California AG has already warned that AI-era advertising must not rely on deferred delivery promises cloaked in high-emotion design. This case is the template. Other sectorsâbiotech, robotics, autonomous vehiclesâwill follow. The Courtâs reasoning here will shape the next generation of consumer protection doctrine.
V. CONCLUSION AND RECOMMENDATIONS FOR JUDICIAL RESPONSE
MindCast respectfully requests that the Court:
Hold that future-functional deceptionâbelief manipulation via AI-era marketing structureâis actionable under California UCL, FAL, and CLRA;
Allow expert evidence on cognitive expectation modeling using scientifically validated simulation methodologies, including CDT-based simulation of how belief is shaped, not just what is literally said;
Clarify that disclaimers cannot cure systemic campaign-induced misalignment when design, tone, and timing indicate immediate functionality.
This is not about punishing innovation. It is about drawing a clear boundary between visionary storytelling and structured deception. That boundary begins here, but its implications will shape how courts evaluate AI-era marketing across all industries for years to come.
