Aim
This paper examines the decay of trust as a central feature of contemporary social division.

Methodology
This paper employs an integrative conceptual review methodology, synthesizing ideas from published and accessible sources to develop a broader account of trust decay. The paper draws on current published and other accessible sources. It employs a non-database-centric strategy that uses Google Scholar and other search engines.

Background
The paper traces this crisis through three related developments: the postmodern challenge to objective truth, the weaponization of communication through disinformation and narrative manipulation, and the erosion of confidence in institutions that once helped stabilize public knowledge.

Findings
The paper argues that polarization is not only a disagreement over facts but also a breakdown in the shared standards by which facts are judged. It shows how emotionally charged framing, motivated reasoning, group identity, and digital amplification contribute to fragmented realities and deepen mistrust.

Contribution
The paper also considers the implications of this trust crisis for democratic discourse, education, journalism, and civic life. It concludes that rebuilding trust requires more than fact-checking.

Impact on Society
It requires a renewed commitment to critical thinking, transparent institutions, media literacy, and shared standards of evidence to support meaningful public debate.

Future Research
Misinformation and disinformation often reveal underlying narratives, experiences, and socio‑political tensions. Therefore, a study of anthropological misinformation could provide useful insights.
