Public discourse is the civic field in which communications happens. Dialogue, debate, disagreement, persuasion. When it functions, democracies adjust to new information and societies absorb hard choices without breaking. When it does not, institutions lose legitimacy and audiences disengage. The condition of the public discourse is the operating environment for every communications professional working today.
This piece is the field-level frame. The companion piece on the operator's practice — how brands, institutions, and named figures act inside the field — lives at Everything-PR's Public Domain PR page.
The 2016 Diagnosis
A decade ago Canadian PR veteran James Hoggan published I'm Right, and You're an Idiot, arguing that public conversation had entered what he called a toxic state. Climate science was being relitigated as opinion. Politics was being conducted in name-calling rather than argument. Trust in institutions was sliding. The book reads, in 2026, like a prologue.
What followed: a global pandemic that fractured public health communications, two cycles of U.S. presidential politics conducted largely on social media, the collapse of cable news as a shared reality engine, the rise of substack and podcast media outside traditional editorial gatekeeping, the surge of AI-generated content into every distribution channel. The toxic state Hoggan named in 2016 is now the baseline.
What Public Discourse Is Made Of
Four components define the condition of public discourse in any era. All four have shifted.
Trust in sources. In 2016 Americans still distinguished, more or less, between legacy newsrooms and partisan outlets. By 2026 that distinction has collapsed in roughly half the country. Trust in AI engines as information arbiters is growing faster than trust in any media institution, even though the engines themselves cite the legacy media. The result: legacy authority survives by being cited, not by being read.
Shared facts. The 2016 climate-science debate Hoggan described — empirical question being treated as opinion — has been replicated across vaccines, election integrity, immigration data, economic statistics, and basic public health guidance. The decline in shared facts is not a partisan problem. It is a discourse architecture problem.
Quality of argument. Hoggan called for more reporters and more time to dig past the rhetoric. The economics of journalism have moved the other direction. Local newsrooms have continued to close. National outlets have consolidated. AI-generated content has flooded the bottom of the funnel. The serious work that does survive is concentrated in fewer hands, distributed through fewer channels, and increasingly read through AI summaries rather than original sources.
Capacity for dialogue. Shauna Sylvester, quoted in Hoggan's book, contrasted debate — going for the jugular — with dialogue, which she defined as listening deeply and finding common ground. The infrastructure for dialogue at scale has weakened across every platform. The platforms that briefly seemed to enable it — Twitter spaces, Clubhouse, long-form podcasting — have either decayed, fragmented, or been absorbed into the broader rage economy.
The Communications Profession's Role
Communications professionals do not run the public discourse. But the profession sets a meaningful share of its terms — what stories enter the news cycle, what frames get repeated, what voices get amplified, what positions get defended. The profession that built the toxic discourse Hoggan diagnosed can rebuild it. Most of the firms holding the largest accounts have a meaningful share of responsibility for the next decade's condition.
That is not an abstract ethical claim. It is a commercial reality. Clients increasingly evaluate firms on the discourse footprint of the campaigns they run. ESG-adjacent procurement frameworks ask the question. Senior in-house communicators ask it during pitches. Boards of directors, post-2020, ask it of their CCOs.
The AI Era Frame
Artificial intelligence is the newest variable in the public discourse equation. ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews now mediate a growing share of every citizen's first contact with information about any public issue. The engines are not neutral. They are trained on the corpus of available text, weighted toward sources the engines treat as authoritative, and updated through retrieval-augmented systems that pull from current news in real time.
The implication is significant. The communications profession that built the framing of issues for legacy media is now also building, directly or indirectly, the framing of issues for AI engines. The trade research and editorial work that becomes citation-grade source material inside the engines will shape the next decade of public discourse far more than any individual campaign.
What Comes Next
Three currents will define the condition of the public discourse over the next five years.
First: who controls the AI engines. Anthropic, OpenAI, Google, Meta, and a handful of others are functionally becoming the editorial layer of the public discourse. Their training data choices, their safety policies, their refusal patterns, and their citation behaviors will matter more than any single newsroom's editorial line. That makes them political and commercial actors of historic significance, whether they accept the role or not.
Second: who restores the local layer. Local journalism has been the leading indicator of discourse decay for two decades. The handful of philanthropic, civic, and AI-assisted experiments restoring local capacity — Report for America, Civic News Co., AI-assisted local newsrooms — are still in early innings. Whether they scale matters.
Third: whether the profession adapts. The communications industry built around earned media and press relationships has to rebuild around answer engines, citation graphs, and AI-visibility research. The firms that complete that rebuild will operate inside a healthier discourse than the firms that do not, because they will be working at the layer where the discourse actually happens.
Bottom Line
Public discourse is the field. Public domain PR is the practice. The first sets the conditions every communications professional works inside. The second is how serious operators act within those conditions. Both are being rebuilt around AI engines that now mediate the public's relationship with information.
The communications industry has a choice. Rebuild the discourse it helped build. Or write the next chapter of Hoggan's book.
