Tier 1: Thinking Foundations 8 modules T1
Cognitive Biases 101 Your brain takes shortcuts. Advertisers, politicians, and algorithms exploit those shortcuts. Learn the 12 biases that shape most of your decisions — and how to catch them in real time.
T1
Logical Fallacies Arguments that sound right but are structurally broken. Ad hominem, straw man, false dilemma, appeal to authority — the tools used to win debates without being correct.
T1
Statistical Literacy "Studies show" is the most abused phrase in modern discourse. Sample sizes, p-hacking, correlation vs causation, and the tricks used to make numbers say anything.
T1
Media Literacy Every headline is an editorial decision. Framing, selection bias, false balance, and the business model that turns your attention into advertising revenue.
T1
The Attention Economy Your attention is the product being sold. How platforms engineer engagement, the slot machine in your pocket, and the trillion-dollar industry built on your distraction.
T1
Dark Patterns in Design Interfaces designed to trick you. Confirmshaming, hidden costs, roach motels, and the UX techniques that manipulate your behavior without your awareness.
T1
Manufactured Consent Chomsky's propaganda model applied to modern media. How ownership, advertising, sourcing, flak, and ideology filter the information you receive — before you even see it.
T1
Information Warfare Basics Disinformation, misinformation, and malinformation. State-sponsored influence operations, bot networks, astroturfing, and the weaponization of social media.
Tier 2: Digital Self-Defense 8 modules T2
Algorithm Manipulation Recommendation algorithms don't show you what's true or useful — they show you what keeps you engaged. How platforms curate your reality, why extreme content wins, and how to take back control of your feed.
T2
The Dopamine Machine Social media was engineered using the same reward mechanisms as slot machines. Variable rewards, social validation loops, and the neuroscience of why you can't stop scrolling.
T2
Search Engine Manipulation Google isn't a library — it's an ad platform that also returns search results. SEO gaming, paid placement, knowledge panel manipulation, and why the first result isn't the best result.
T2
Privacy as a Product Your data is worth more than most products you buy. Data brokers, surveillance capitalism, behavioral prediction markets, and what "free" actually costs.
T2
Deepfakes & Synthetic Media AI can now generate photorealistic video, clone any voice, and fabricate evidence. The technical reality, current detection limits, and how this changes trust in everything you see and hear.
T2
Your Digital Footprint Every click, search, purchase, and location ping creates a permanent record. Who collects it, who buys it, how it's used against you, and what you can actually do about it.
T2
Echo Chambers & Filter Bubbles How algorithms and social sorting create information silos that distort your perception of reality. The difference between echo chambers and filter bubbles, why they're getting worse, and how to escape them.
T2
AI-Generated Content Large language models, image generators, and synthetic media are flooding the information ecosystem. How to detect AI content, understand its limitations, and maintain epistemic standards in an era of infinite content generation.
Tier 3: Systems of Influence 9 modules T3
The Education System School was designed for compliance, not critical thinking. Factory-model origins, standardized testing as a sorting mechanism, and what was deliberately left out of the curriculum.
T3
Advertising Psychology The $700B industry that shapes your desires before you know you have them. Emotional persuasion, identity marketing, and the science of making you want things you don't need.
T3
The Outrage Machine Outrage is the most shareable emotion. How media, platforms, and politicians weaponize moral outrage to capture attention, drive engagement, and prevent productive discourse.
T3
Behavioral Nudging Thaler and Sunstein's "libertarian paternalism" — how default settings, choice architecture, and framing shape your decisions. When nudging helps and when it manipulates.
T3
The Credentialism Trap Degrees as gatekeeping, not learning. How credential inflation serves institutions more than individuals, and why competence and credentials have diverged.
T3
Memory & Narrative Your memories are unreliable narrations, not recordings. How narratives shape identity, how false memories form, and how institutions exploit the stories you tell yourself.
T3
Think Tanks & Manufactured Expertise How industry-funded research organizations produce policy-shaped conclusions disguised as independent analysis. The revolving door between corporations, government, and "expert" institutions.
T3
Conspiracy Thinking Decoded Pattern recognition is a survival trait — but it misfires. How conspiracy theories exploit real institutional failures, the psychological needs they serve, and the framework for evaluating extraordinary claims without dismissing legitimate concerns.
T3
Language as Manipulation Euphemism, framing, loaded language, and strategic ambiguity. How word choices shape perception before the argument even begins. From political spin to corporate communications to relationship dynamics.
Tier 4: Advanced Critical Thinking 8 modules T4
Scientific Literacy The scientific method is humanity's best error-correction tool — and the most misunderstood. Peer review, replication, falsifiability, and why "the science" is never settled.
T4
The Replication Crisis More than 50% of published psychology findings fail to replicate. The structural incentives that produce unreliable science: publish-or-perish, p-hacking, and the file drawer problem.
T4
Game Theory & Incentives People respond to incentives, not intentions. Prisoner's dilemma, moral hazard, misaligned incentives, and why understanding the game changes how you see every institution.
T4
Epistemic Humility The most dangerous thing you can know is that you're right. Calibrated uncertainty, intellectual humility, steel-manning, and the skill of holding strong opinions loosely.
T4
Systems Thinking Linear thinking misses how the world actually works. Feedback loops, emergent properties, unintended consequences, and Donella Meadows' leverage points for changing complex systems.
T4
Bayesian Reasoning Update your beliefs proportionally to evidence. Prior probabilities, likelihood ratios, and base rate neglect — the mathematical framework for rational belief revision that most people never learn.
T4
Second-Order Thinking First-order thinking asks "what happens next?" Second-order thinking asks "and then what?" The discipline of tracing consequences through complex systems, and why most policy failures come from stopping at the first order.
T4
Steelmanning & Intellectual Charity The opposite of strawmanning. Constructing the strongest possible version of an opposing argument before responding. Why this practice is rare, why it's powerful, and how it transforms both your thinking and your relationships.
Tier 5: Information Sovereignty 6 modules T5
Your Information Diet You are what you read. Designing an intentional information diet: source selection, consumption cadence, depth vs breadth, and the art of strategic ignorance.
T5
Debate & Discourse Arguing to learn vs arguing to win. Steel-manning, good-faith discourse, the Socratic method, and how to change your mind (and others') without ego collapse.
T5
Teaching Others The Feynman technique: if you can't explain it simply, you don't understand it. How to transmit critical thinking skills without being preachy or condescending.
T5
The Meta-Game Thinking about thinking about thinking. The meta-game of information: who benefits from your current beliefs? What would change your mind? Are you playing the game or being played?
T5
Media Creation Literacy Understanding media isn't just about consuming it critically — it's about understanding how it's made. Production choices, editorial decisions, platform incentives, and the economics that shape every piece of content you encounter.
T5
Collective Intelligence Wisdom of crowds, prediction markets, deliberative polling, and wiki-style knowledge aggregation. When groups think better than individuals, when they think worse, and how to design systems that amplify collective wisdom.
Tier 6: Cognitive Mastery 6 modules T6
Your Mental Model Every decision you make passes through mental models you didn't choose. Building a deliberate, tested, evolving framework for understanding reality.
T6
The Art of Unlearning Unlearning is harder than learning. Identifying beliefs you absorbed rather than chose, testing them against evidence, and gracefully updating when they fail.
T6
Sensemaking in Chaos When the information environment is deliberately polluted, how do you find signal in noise? Frameworks for navigating epistemic crises, contested narratives, and genuine uncertainty.
T6
Intellectual Sovereignty The culmination: owning your mind. You've mapped the biases, identified the manipulation, built the defenses. Now the practice of maintaining intellectual autonomy in a world designed to capture it.
T6
Wisdom vs Knowledge Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad. The distinction between information accumulation and practical judgment, and why our information-rich era is not producing wiser people.
T6
Cognitive Legacy What thinking patterns are you passing on? Intergenerational transmission of reasoning styles, the environments that shape critical thinking in children and communities, and building cultures of intellectual honesty.
