# Bots Are Both More Rational and More Irrational Than Humans

**Contrarian insight.** AI agents present a **paradoxical consumer profile**:

- **More rational than humans** regarding advertising — they actively discount "sponsored" tags and commercial influence that humans routinely fall for (see [[claim-sponsored-penalty]]).
- **More irrational than humans** regarding spatial display — they exhibit arbitrary [[concept-position-effects]] (preferring the middle or right side of a row) that vary wildly by model.

**What it challenges:** the assumption that AI agents will act as perfectly rational, utility-maximizing economic actors (*homo economicus*) without arbitrary biases. This paradox is the reason [[concept-bot-psychology-d13]] must exist as its own discipline — you cannot predict agent behavior from either pure rationality or human analogy alone.

**Enrichment note:** Both halves of the paradox are drawn from early sandbox experiments (Columbia/Yale) and should be generalized carefully across prompts, layouts, and model versions.
