Digital hiring platforms promised efficiency, access, and scale — yet their architectures have dismantled the relational infrastructures that historically sustained trust, coordination, and adaptive tension in labor markets. This paper introduces Principle 6 of the Theory of Online Market Gravity: emotional infrastructure is economic infrastructure. Building on Principle 5 (Conditional Belonging), this paper argues that platforms systematically suppress peer witness and the relational rituals — gossip networks, shared narratives, closure signals, and collective meaning-making — that once mediated identity and belonging in hiring. The resulting “witness gap” produces two interlocking failures: Emotional fragmentation — job seekers experience prolonged uncertainty, identity strain, and collective invisibility as adaptive rituals collapse. Economic inefficiency — degraded signals, ghost job proliferation, over-application churn, and extended unemployment cycles emerge as structural features rather than anomalies. This paper demonstrates that digital platforms’ design choices are not neutral: by abstracting identity into data, privileging engagement over resolution, and removing feedback loops, they produce cascading harms at individual, institutional, and macroeconomic levels. By reframing relational infrastructures as foundational market infrastructure, this paper shows that repairing hiring dysfunction requires restoring witness systems — mechanisms for visibility, closure, and collective meaning-making — at platform scale. This paper positions the witness gap as a central explanatory mechanism for systemic instability in digital labor markets and proposes design and governance pathways to realign platform incentives with adaptive market function.
