Definition
Humans are not irrational — they are arational. Logic is one input among many. Emotion, instinct, and subconscious cues shape most behavior most of the time. The brain processes 11 million bits of information per second; only 40 reach conscious awareness. The rest are processed through five categories of predictable distortion that bend behavior away from pure logic in consistent, anticipatable ways. Every operator, every cast member, every Guest is arational. The operator who designs their building as if people are rational — who communicates through logic alone, who builds systems assuming people will follow the most efficient path, who expects stated values to produce aligned behavior — is designing for a human being that does not exist. The operator who designs with arational behavior in mind builds with the grain of human nature rather than against it.

Explanation
— [Temporal Discounting]
The brain’s systematic tendency to overweight what is immediate and underweight what compounds. Five grandchildren: [Present Bias], [Future-Self Disconnect], [Projection Bias], [Exponential Growth Bias], [Opportunity Cost Neglect].
— [Attention Distortion]
The brain’s systematic tendency to notice some signals while filtering others, and to interpret what it notices through the lens of what came first, what was most vivid, what came just before, and what was subtly suggested before deliberation began. Five grandchildren: [Anchoring], [Framing Effect], [Salience Bias], [Contrast Effect], [Priming].
— [Choice and Design Distortion]
The systematic ways that the structure of a decision environment shapes what people do, often more powerfully than the information or incentives surrounding it. Three grandchildren: [Choice Overload], [Label and Category Effects], [By Design Or By Default].
— [Judgment Distortion]
The systematic ways that judgment bends away from objective analysis through invisible shortcuts. Three grandchildren: [Anchoring] (cross-referenced from [Attention Distortion] — first inputs steer all subsequent judgment), [Overconfidence Bias] (people overestimate the reliability of their own judgments — the operator who is certain their read is correct is most at risk of being wrong; the confident pre-shift that doesn’t account for what could go wrong, the certain vendor negotiation that doesn’t account for what the vendor actually needs), [Loss Aversion] (losses hurt more than equivalent gains feel good — the cast member who protects their current standing rather than risk visible failure, the operator who holds a failing standard rather than admit it needs to change, the Guest who defaults to the familiar rather than try something new).
— [Social Distortion]
The systematic ways that social context bends individual judgment and behavior. Three grandchildren: [Conformity Bias] (people align with the group even when they privately disagree — the pre-shift where everyone nods and nobody objects is running conformity bias, not alignment; the post-shift where nobody surfaces the real problems because the dominant read is “it was fine”), [Social Proof] (others’ behavior becomes a guide in uncertain moments — the Guest who orders what the table next to them ordered, the cast member who holds the standard the senior cast member holds rather than the one the operator set, the new hire who absorbs the building’s actual culture before they absorb the stated one), [Groupthink] (the desire for harmony suppresses dissent and weakens judgment — the leadership team that approves a bad decision because nobody wanted to be the lone voice, the pre-shift that produces false consensus, the operator who mistakes a quiet cast for an aligned one).
