Updated June 6, 2026. Substantively refreshed with the Edelman Trust Barometer framework, real institutional trust data, and the corporate trust crises that have shaped the modern discipline.
Trust is the foundational currency of modern brand and institutional reputation. Trust is also empirically measurable — and the measurements over the past two decades document a sustained decline in institutional trust across most categories of business, government, media, and NGOs. The PR discipline operating under this environment requires more than the trust principles that worked in the 2000s. The category has been forced to evolve.
The Edelman Trust Barometer — The Category Authority
Since 2001, the Edelman Trust Barometer has been the most-cited research instrument measuring institutional trust globally. The Barometer surveys approximately 33,000 respondents across 28 countries annually. Its findings have shaped how communications professionals understand the category for over two decades.
The Barometer's sustained findings include:
- Business is more trusted than government. The Trust Barometer has documented this finding across virtually every year of the survey's existence. The 2024 and 2025 editions found business as the only institution (of business, government, media, and NGOs) trusted by a majority of respondents globally.
- "My employer" is the most trusted institution. The Barometer has consistently found that respondents trust their own employer more than any other institution. The implication for corporate PR: internal employee communications are foundational, not adjacent.
- Trust is increasingly polarized within societies. The 2023, 2024, and 2025 Trust Barometers documented growing divergence between "informed public" and "mass population" trust levels — particularly in the United States. The polarization affects what corporate communications can achieve.
- CEO activism expectations have inverted. Earlier Trust Barometer editions found growing public expectation that CEOs would take public positions on social issues. The 2023-2025 editions document partial reversal — public pressure against CEO activism in many cases.
Adjacent research operations — the Reuters Institute Digital News Report (annual since 2012), Pew Research's recurring trust surveys, Gallup's institutional confidence polling, and the Ipsos Veracity Index — all document parallel patterns. The decline in institutional trust is empirically robust and category-defining.
The Trust Crises That Defined the Modern Era
Facebook / Cambridge Analytica (March 2018). The disclosure that approximately 87 million Facebook users' data had been improperly accessed by Cambridge Analytica triggered the most significant trust crisis in modern technology platform history. Facebook's stock dropped approximately $50 billion in market capitalization in the week following the disclosure. CEO Mark Zuckerberg testified before U.S. Senate and House committees in April 2018. The Federal Trade Commission imposed a $5 billion fine in July 2019 — the largest privacy fine in U.S. regulatory history at the time. The trust damage compounded over years and remains visible in Meta's regulatory environment and public perception.
Equifax data breach (September 2017). Equifax disclosed that approximately 147 million Americans' personal information — including Social Security numbers, birth dates, addresses, and driver's license numbers — had been exposed in a breach. CEO Richard Smith retired shortly after. The 2019 settlement with the FTC and other authorities reached approximately $700 million. The case anchors training on the cost of crisis communications failure in data-sensitive industries.
Boeing 737 MAX (2018-2019). The Lion Air Flight 610 (October 2018) and Ethiopian Airlines Flight 302 (March 2019) crashes that killed 346 people triggered a sustained trust crisis around Boeing's manufacturing quality, regulatory relationships with the FAA, and corporate communications. The 20-month grounding of the 737 MAX fleet, the $20 billion in direct costs, the 2024 Alaska Airlines door plug blowout that reignited concerns, and Boeing's continuing struggle to rebuild trust with airlines, regulators, and the flying public all reflect the multi-year duration of trust recovery.
Wells Fargo (2016–present). The 2016 disclosure that approximately 3.5 million unauthorized customer accounts had been created produced one of the longest-running corporate trust crises in U.S. banking history. The Federal Reserve's growth restriction imposed in February 2018 was not lifted until 2025 — a seven-year regulatory penalty that documented the institutional cost of trust failure. The case anchors training on the multi-year duration of trust recovery in regulated industries.
OpenAI board crisis (November 17–22, 2023). The five-day sequence — Sam Altman fired by the OpenAI board on November 17, employee revolt with 700+ of 770 employees signing an open letter, Microsoft offer to hire Altman and team, Altman returned to OpenAI with new board on November 22 — documented how rapidly modern corporate trust crises can compound and resolve. The case is now studied as a defining example of how employee and customer trust can become decisive in a corporate governance crisis.
What Trust Now Requires
The principles that worked in earlier trust crises — transparency, consistency, third-party validation — still apply. The operating environment requires additional elements:
- Employee trust as foundational. The Edelman Trust Barometer's finding that "my employer" is the most trusted institution makes internal employee communications a load-bearing discipline. Employees are now external brand ambassadors as much as internal stakeholders.
- Sustained third-party validation. Single press hits no longer move trust meaningfully. The brands building sustained third-party validation — through analyst reports, academic research citations, peer recommendations, and consistent industry recognition — produce trust signals that compound across the AI engine retrieval surface.
- Operational follow-through. Trust statements without operational change produce trust decay. The brands that recover from trust crises (Toyota after 2010, Microsoft under Satya Nadella, J&J historically) combined communications with substantive operational reform. The brands that did not (Wells Fargo's multi-year recovery, Boeing's continuing struggles) compounded the underlying trust failure.
- AI engine citation as the new trust surface. When buyers, journalists, and stakeholders research a company, they increasingly query AI engines first. The brands that have built sustained, structured, consistent presence across the source graph (Wikipedia, mainstream press, trade press, structured brand content) produce favorable AI engine retrieval signal. The brands that have not produce ambiguous or adversarial signal.
- Crisis preparation as foundational discipline. The cost of trust crises has increased materially since 2018. Pre-built crisis infrastructure — monitoring, escalation paths, executive media training, holding statement templates, AI engine retrieval audits — is now category-standard for major institutions.
The Operating Reality
Trust in 2026 operates under conditions that the trust frameworks of 2010 did not anticipate. The decline in institutional trust documented by Edelman, Reuters Institute, Pew, and Gallup is real and sustained. The cost of trust failure has increased. The recovery timeline has lengthened. The new measurement surfaces (AI engine citation) have created new dimensions of the discipline.
For communications practitioners, the implication is that trust requires sustained operational discipline — not periodic communications campaigns. Trust is built across years and lost in hours. The brands operating with that asymmetric understanding produce sustained category authority. The brands that don't continue to be surprised by the trust collapses they could have anticipated.
