Course overview
What you'll learn
Dan Ariely's Predictably Irrational reveals how we systematically deviate from rational decision-making through concepts like the relativity trap, the power of FREE!, arbitrary coherence in pricing, and the high cost of social norms. You've likely encountered a predictably irrational summary that lists these experiments, but knowing about the decoy effect or endowment effect isn't the same as catching yourself falling for them in real time. Reading about anchoring doesn't teach you to recognize when your salary expectations, negotiation stance, or purchase decisions are being manipulated by irrelevant numbers.
This course makes you work with Ariely's findings through case studies where you identify which bias is at play before checking your reasoning, flashcards that test whether you can distinguish between different types of irrationality, and written assignments where you analyze your own recent decisions through the lens of behavioral economics. You'll listen to podcast episodes that debate whether Ariely's conclusions hold across cultures, practice designing choice architectures that either exploit or counteract these biases, and receive AI feedback on your ability to apply these frameworks to business, personal finance, and relationship scenarios. Each module includes retrieval practice that forces you to recall experiments and predict outcomes before seeing results.
This course works for anyone making decisions under uncertainty—managers designing incentive structures, marketers crafting offers, individuals trying to understand why they overspend or procrastinate, or students of psychology and economics who want applied fluency. If you've ever wondered why you behave against your own interests, this course builds the pattern recognition to catch it happening.
Course curriculum
8 modules, designed for mastery
The Relativity Trap: Why We Judge Everything Comparatively
~60 minExplore how context shapes perception through Ariely's experiments on comparative decision-making. You'll analyze real pricing structures to identify decoy options and practice spotting when your judgments are being anchored by irrelevant comparisons.
The Fallacy of Supply and Demand: Arbitrary Coherence and Price Anchoring
~75 minWork through Ariely's Social Security number experiments and examine how initial prices become self-perpetuating references. Apply this to salary negotiations and consumer behavior through case studies that test your ability to identify arbitrary anchors.
The Cost of Zero Cost: Why FREE! Makes Us Irrational
~55 minInvestigate the disproportionate appeal of free options through Ariely's chocolate experiments. You'll design promotional scenarios and predict consumer behavior, then analyze why free shipping, trials, and add-ons distort our cost-benefit analysis.
Social Norms vs. Market Norms: When Money Ruins Relationships
~80 minStudy the collision between social exchanges and financial transactions. Through workplace scenarios and personal relationship case studies, you'll practice identifying when introducing payment degrades motivation and goodwill, applying Ariely's daycare fine experiments.
The Influence of Arousal: Decision-Making in Emotional States
~50 minExamine Ariely's experiments on how emotional and physical arousal changes preferences and predictions. Work through scenarios involving anger, attraction, and stress to understand why we systematically underestimate state-dependent behavior.
Procrastination and Self-Control: The Problem with Future Selves
~70 minApply Ariely's research on present bias and commitment devices to your own behavior. You'll design self-control mechanisms, analyze why deadlines impose structure, and practice creating precommitment strategies for health, finance, and productivity goals.
The High Price of Ownership: Endowment Effect and Loss Aversion
~65 minWork through experiments showing why we overvalue what we own. Analyze business negotiations, pricing strategies, and personal attachment to identify when the endowment effect is distorting valuation, and practice techniques to counteract it.
Expectations and Placebo Effects: How Beliefs Shape Experience
~85 minInvestigate how price, branding, and expectations alter actual experiences through Ariely's beer and pain medication experiments. Apply these principles to marketing, product positioning, and personal perception, testing your ability to predict belief-driven outcomes.

Everything you need
Six learning formats, one complete experience
Every module delivers content across multiple formats — each chosen for a specific learning science reason.
AI-Generated Podcasts
Two voices — an expert and a curious learner — break down complex topics in engaging conversations. Listening activates different cognitive pathways than reading, deepening comprehension.
Structured Key Concepts
Clear, pedagogically-framed core knowledge organized for progressive understanding. Each concept builds on the last, creating a coherent mental model.
Real-World Case Studies
Applied examples from actual scenarios show how theory works in practice. Case-based learning bridges the gap between knowing a concept and using it.
Interactive Flashcards
Active recall — testing yourself — is proven to improve retention by 50%+ compared to passive review. Flashcards make retrieval practice effortless.
Quizzes & Assessments
Multiple-choice questions with detailed explanations test understanding and reveal knowledge gaps before you move on. Mastery-based progression ensures nothing is skipped.
Written Assignments
Writing forces deeper processing than multiple choice. Synthesize your learning by applying concepts to realistic scenarios, with instant AI-powered feedback on your analysis.
Built on learning science
Every format is here for a reason
Erudia courses combine five proven learning methods into one seamless experience — so knowledge sticks, not just passes through.
Spaced Exposure
Content revisited across multiple formats — audio, text, flashcards, quizzes — reinforces memory through varied repetition. Each encounter strengthens the neural pathway differently.
Retrieval Practice
Flashcards and assessments force active recall — proven to improve retention by 50%+ versus passive reading. Every quiz is a memory-strengthening event.
Synthesis Through Writing
Written assignments require deeper processing than multiple choice. When you explain a concept in your own words, you discover what you truly understand and what you don't.
Multi-Format Learning
Audio, reading, case studies, and interactive practice mirror how people naturally absorb complex information. Each format activates different cognitive pathways, building richer understanding.
Mastery-Based Progression
You can't skip ahead until you've demonstrated understanding. This isn't arbitrary — it's how lasting learning works. Each module builds on the foundations laid by the previous one.
What learners are saying
Real courses, real feedback
“I expected a surface-level overview, but the course actually got into altitude-specific soil biology, frost-resilient guild planting, and water management for mountain terrain. The case studies were specific enough that I could apply them to my own site. The podcast episodes were perfect for listening while working in the garden.”

“I've read the book twice, so I was skeptical a course could add anything. It did. The module on counter-strategies completely changed how I think about defensive positioning, and the written assignments forced me to actually apply the laws to situations I'm dealing with at work — not just passively absorb them.”

“This covered territory I haven't seen in any other course — residual valuation models for streaming libraries, probabilistic forecasting for franchise IP, portfolio construction across film, TV, and gaming assets. The quizzes caught gaps in my understanding I didn't know I had. Genuinely useful for anyone working in media finance.”

FAQ
Frequently asked questions
No. The course covers all the key experiments and concepts, so you can start without reading the book. That said, having read it enriches the experience—you'll recognize the studies and can focus entirely on application rather than comprehension. Many learners use this course as a companion while reading or as a way to deeply internalize ideas after finishing.
Both. Ariely's research shows how these biases work regardless of intent. The course helps you recognize when you're being influenced (by marketing, pricing, social pressure) and when you're falling into these patterns yourself. You'll work through ethical implications in the Social vs. Market Norms module, but the primary goal is building awareness, not manipulation tactics.
Predictably Irrational goes beyond listing biases—it demonstrates systematic patterns in when and how we deviate from rationality. Knowing about anchoring is different from catching it in real-time salary negotiations or price comparisons. This course builds recognition fluency through repeated practice identifying which specific form of irrationality is operating in ambiguous scenarios, not just memorizing definitions.
