INTRODUCTION

English translation pending.

CORE DEFINITION

The privacy paradox describes the inconsistency between stated privacy attitudes and actual disclosure behavior. Surveys show strong concern about data collection, while the same users accept tracking, share personal information for small discounts, and skip reading privacy notices. The gap reflects bounded rationality, present bias, and the cognitive cost of evaluating complex terms rather than genuine indifference to privacy.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Privacy by Design: set protective defaults instead of relying on what users say they want. - Behavior Over Statements: judge privacy risk by observed disclosure, not by survey responses. - Nudge Selection: simplify choices so decisions match users considered preferences.

Anchor fast decisions

Privacy costs are delayed, diffuse, and hard to evaluate, while the benefit of disclosure is immediate and concrete. Limited attention and cognitive load push users toward the easy option, so stated concern does not translate into protective behavior. This breaks any design assumption that users will defend their own data.
