Metaphors as Scaffolds: Spatial, Embodied, Fantastical, and Relational Framings for Youth Usable Privacy Design

2026-05-07

AI Summary

This study addresses the limitations of current privacy designs for adolescents, which often reduce privacy to abstract management tasks while overlooking its relational, contextual, and embodied cognitive dimensions. Through three qualitative studies involving youth aged 13–24, the research systematically integrates metaphor analysis and situated design evaluation to propose, for the first time, that metaphor selection constitutes a critical ethical decision in privacy design. Findings indicate that spatial metaphors reduce cognitive load, embodied metaphors facilitate norm negotiation, and fantastical metaphors enhance perceived control and engagement, whereas relational metaphors may inadvertently weaken boundary awareness—particularly posing risks in AI companion products. These insights offer both theoretical grounding and practical pathways for designing usable privacy mechanisms aligned with adolescent cognitive characteristics.

Abstract

Mainstream usable privacy design frames privacy as administrative work -- settings, toggles, consent checkboxes -- abstracted from the relational, contextual, and embodied registers in which youth reason about disclosure. Drawing on a cross-project reading of three prior studies with youth aged 13--24, we examine how the metaphors that scaffold a privacy interaction shape the reasoning young users bring to it. \textit{Spatial} metaphors reduce cognitive load by recruiting intuitions about navigating physical space. \textit{Embodied} metaphors furnish a shared moral vocabulary that makes implicit norms about public and private space negotiable among users. \textit{Fantastical} metaphors recast privacy management as discoverable play, raising engagement with the granular controls that nuanced self-presentation requires. \textit{Relational} metaphors, by contrast, can lead youth past their own stated boundaries when felt intimacy masks institutional data flow, a risk already visible in AI companion products. Metaphor selection, we argue, is best understood as a first-order ethical design decision for youth privacy.
