Mapping the invisible architecture of judgment.Tools for clearer thinking and better decisions in an age of artificial intelligence.
Interactive explorer of 20+ mental shortcuts — where they help, where they hurt, and how to deploy them deliberately.
An interactive periodic table of cognitive biases. Select elements to synthesize archetypes and diagnose real-world decision failures.
A head-to-head challenge pitting your gut instincts against an AI baseline. Reveals where human intuition excels — and where it reliably fails.
Experiential simulations engineered to trigger specific cognitive biases. Identify the trap before it closes.
Measures the gap between your confidence and your accuracy. Build the habit of knowing what you know — and what you don't.
Walks you through complex problems step by step, surfacing assumptions, alternatives, and blind spots at each stage.
Generates a structured adversarial perspective on any decision. Forces genuine consideration of the alternative you're resisting.
Maps competing values onto a visual landscape, making the real costs of every option visible before you commit.
Identifies when you're deciding too fast, too slow, or with the wrong deliberation level for the stakes at hand.
Surfaces the statistical baseline before any prediction. Counters optimism bias by anchoring judgment in population-level evidence.
Maps which decision sub-tasks belong to human judgment and which belong to algorithmic processing.
Surfaces and ranks your actual values — not the ones you assume you hold — before a high-stakes decision demands you choose.
Reframes decisions held hostage by prior investment entirely around future value, severing the anchor of past cost.
Interactive demo of loss aversion and reference dependence. Reveals how your value function systematically distorts choice.
Separates meaningful patterns from statistical noise in data, decisions, and incoming information.
Surfaces the gap between how an experience will feel and how it will be remembered. Design for both selves.
Assume the decision has already failed, then reconstruct why — before you've committed and while you can still change course.
Converts any probability claim into Bayes' theorem, natural frequencies, and icon arrays. Makes conditional probability intuitive.
Long-form investigations into the architecture of judgment, choice, and the minds that mapped them
The unlikely journey from working-class Portland to behavioral decision science, and the people, risks, and ideas behind Yellowlights.ai.
In a world built for instant responses, the pause is the most radical design choice available. A case for deliberate hesitation.
From Aristotle's phronesis to AI-augmented forecasting, the lineage of thinkers who built the science of how we choose.
He was the most brilliant psychologist of his generation. He died at fifty-nine. History has been catching up ever since.
He spent his life mapping the flaws in human judgment. At ninety, he made his final decision. The most deliberate of all.
For a decade, Kahneman and Tversky were inseparable. What they built changed economics, law, and medicine — and how any honest person looks at their own mind.
He kept a chalkboard nobody else could read. Four decades later, it earned him a Nobel Prize.
He's the most frequently cited legal scholar in America. The real question is whether there's anything he hasn't written about.
Philip Tetlock spent decades studying expert prediction. What he found should unsettle anyone who trusts their own convictions.
Two camps spent decades talking past each other. Then they wrote a paper together and, to their own surprise, couldn't find a fight worth having.
A review he didn't like led him, eight years and one unlikely friendship later, to write the truest book of his career.
Cognitive bias isn't a character flaw. It's an evolutionary mismatch — ancient hardware running in a modern environment.
The debiasing industry assumes your intuitions are the enemy. Gerd Gigerenzer disagrees — and so does the data.
The most dangerous thing a decision-maker can do is confuse how certain they feel with how right they are.
Everyone talks about bias. Almost no one is talking about the larger problem: random variability in judgments that should be identical.
The quality of most decisions is determined before deliberation begins. Everything is framing.
Modern work culture rewards urgency. It penalizes deliberation. Here's the cognitive cost nobody's accounting for.
Organizations don't just inherit their founders' ideas — they inherit their biases. A structural analysis of how shortcuts become policy.
Training individuals to think better rarely works. Redesigning the environment they decide inside of usually does.
AI doesn't just inherit human cognitive biases — in key domains, it amplifies them. The question isn't whether to use it. It's how.
Two retail field experiments reveal why adjusting an algorithm’s inputs can help while overriding its decisions can hurt.
Booking.com made testing a challenge to authority. Its own experiment-quality audit shows why that culture also needs scrutiny.
A bakery experiment tests when checklists support good work and when documenting it gets in the way.
Too Good To Go turned uncertain surplus into a marketplace. Its growth raises questions about value and measurable waste reduction.
