Moral pathology of Instagram's structural design principles

Social media platforms such as Instagram, through their specific structural design, exert profound influences on users’ behavior, identity formation, and psychological well-being. This qualitative study aims to uncover Instagram’s underlying design principles and critically analyze their ethical implications. Data were collected through systematic observation of the platform’s interface (from October to December 2024) and document analysis of Meta’s official policies, technical reports, and peer-reviewed scholarly literature (2018–2025). Thematic analysis (using MAXQDA 2022) and a systematic literature review yielded 7 overarching themes (design laws) and 48 organizing themes (design principles). Key principles include “prioritizing engaging and popular content,” “encouraging prolonged user retention,” “relative freedom in content and identity expression,” and “algorithmic content recommendation based on behavioral tracking.” Ethical harm analysis reveals that these design principles generate extensive negative consequences through three pathways: (1) direct effects on content creators (e.g., incentivizing superficial, sensational, or deceptive content); (2) indirect effects on consumers via such content (e.g., promoting misinformation, materialism, and unrealistic lifestyles); and (3) direct effects on consumers (e.g., content addiction, filter bubbles, exposure to harmful material, and erosion of ethical values). The findings underscore the urgent need for “Ethics by Design” in social media development and caution that without structural reform, future digital platforms will exacerbate psychological and societal crises.
