Defaults can influence behavior by changing the cost of choosing otherwise.

This page isolates one claim from the wider argument of The Human OS Manual.

The classification describes the evidence supporting this claim, not the Human OS framework as a whole.

Johnson and Goldstein show that default structure can substantially affect choice by changing what happens when a person takes no action and what is required to choose otherwise.

The study does not establish that every behavior is controlled by defaults or that choice architecture removes individual agency.

This evidence concerns structured choice environments in which a default changes what happens when no action is taken and what is required to choose otherwise. The book's wider friction interpretation is authorial.

Supported by appropriate human studies, major reviews, trials, cohort research, or converging evidence. The strength of the category does not remove population, dose, timing, or context limitations.

Sources are listed according to the role they play in this claim. One source may provide direct support, another may explain a mechanism, establish a limitation, or prevent an interpretation from becoming broader than the evidence allows.

The printed book preserves the claim inside the argument that gives it meaning. These references connect the current digital record to the first-edition evidence trail.

This claim connects to the following parts of the Human OS architecture. The module labels locate the claim inside the framework; they do not imply that the research source validates the architecture itself.
