Key Ideas
Nudge Theory
Small changes in choice architecture can dramatically influence decisions without restricting freedom. This is "libertarian paternalism"—preserving choice while steering toward better outcomes.
Mental Accounting
People treat money differently depending on its source and intended use, violating the economic principle of fungibility. We create mental "buckets" that influence spending behavior.
Endowment Effect
People value things more highly simply because they own them. The mug you own is worth more to you than an identical mug you don't own.
Planner vs. Doer
We contain two selves: a far-sighted planner who makes good intentions and a myopic doer who acts on impulse. Understanding this tension is key to behavior change.

Influence on My Work
Thaler's work is foundational to my thinking on Agentic Decision Sciences. His key insight—that context shapes choice—applies directly to how we design AI systems that interact with human decision-makers.
Specific Applications
- AI as Choice Architect: AI systems inevitably structure the choices presented to users. Thaler's framework helps us think about the ethical dimensions of this role.
- Default Settings in AI: What should AI systems do by default? Like Thaler's retirement savings research, the default matters enormously.
- Nudges vs. Manipulation: Where is the line between helpful nudging and harmful manipulation? Thaler's "asymmetric paternalism" principle offers guidance.
"If you want people to do something, make it easy. Remove the obstacles."
