When Belief Becomes Evidence: Conspiracy Thinking and the Collapse of Institutional Trust
A Manhattan Foundation poll released on 1 May 2026 found that 47 percent of Democrats believe the attempt on Donald Trump's life in Butler, Pennsylvania, was fabricated or staged. Let that number settle. Nearly half of one of America's two major parties — a party that styles itself the defender of democratic norms, the party of evidence and expertise — has settled on the view that a former president faked his own near-assassination. This is not a fringe phenomenon. This is the center of the Democratic coalition.
The poll's release coincided with Trump himself dismissing NATO as a "paper tiger" — an alliance that, he said, had failed to support the United States in its confrontation with Iran despite trillions in American spending on the bloc. Whether one agrees with Trump's framing of NATO or not, the coincidence is instructive. You have a political movement arguing on one side that American institutions cannot be trusted to stage a crime, while the political figure it opposes argues that the alliance those institutions built cannot be trusted either. Both claims inhabit the same epistemic universe: one where trust in established fact has become a partisan variable.
The Poll Is Not the Problem
Forty-seven percent of Democrats embracing a conspiracy theory about an assassination attempt would be alarming on its own. But it becomes something more significant when placed alongside the broader trajectory of American political information consumption. Polls tracking belief in specific conspiracy theories — that the 2020 election was stolen, that the Sandy Hook shooting was staged, that chemtrails poison the population — have been climbing for years across both parties. What the Manhattan Foundation data reveals is that the phenomenon is not ideologically located. Conspiracy thinking is a bipartisan habit, differentiated by content but uniform in structure. Each party's base相信自己是被针对的受害者, believing itself targeted by elaborate hoaxes designed to maintain power the other side does not legitimately hold.
The structural logic is simple and corrosive. When a political community loses confidence in the institutions meant to adjudicate truth — courts, intelligence agencies, mainstream media, electoral administration — it fills the vacuum with whatever narrative its preferred voices provide. For Democrats, that narrative now includes the idea that Trump staged his own shooting to engineer sympathy and consolidate political power. For Republicans, the corresponding article of faith is that the 2020 election was systematically rigged. Both cannot be simultaneously true, and both require the same underlying premise: that official accounts cannot be trusted and that the real truth is hidden.
NATO's Credibility Problem Is Different — But Related
Trump's dismissal of NATO as a paper tiger operates in a related but distinct register. This is not conspiracy thinking in the narrow sense. The alliance has genuinely struggled to meet defense spending commitments. European members have, at various points, underdelivered on the two-percent-of-GDP target that Washington has pressed for years. The grievances Trump articulates are rooted in a genuine asymmetry — the United States has carried a disproportionate share of the alliance's operational burden, a point that predates Trump's political emergence and reflects real structural imbalances in how NATO allocates costs and responsibilities.
But the framing matters. Describing NATO as a paper tiger is not a policy critique. It is a declaration about the unreliability of the institutional arrangements America built after 1945 — arrangements that, whatever their imperfections, have undergirded European stability and American influence for eighty years. When the president of the United States characterizes the alliance as fundamentally fraudulent, he is doing something more consequential than complaining about budget allocations. He is signaling that the rules-based order is optional, that commitments made by previous administrations can be unilaterally revalued, that allies should not plan around American guarantees because those guarantees fluctuate with electoral outcomes.
This matters for a reason that goes beyond the immediate geopolitics. The credibility of American commitments — to NATO, to Japan, to South Korea, to the broader web of alliances that constitute American hegemony — depends on predictability. If allied governments cannot be confident that an American president will defend them, they will seek alternative arrangements. That is not a theoretical risk. It is already visible in European discussions about strategic autonomy, in Asian hedging by countries that once considered American protection a fixed variable.
The Feedback Loop
What connects the poll numbers and the NATO rhetoric is not just a shared atmosphere of institutional distrust. It is a feedback loop. American politicians — and here the pattern crosses party lines, though Trump has made it more explicit than most — have learned that attacking institutions generates political returns. The intelligence community, the Justice Department, the Federal Reserve, the press: each has been subjected to sustained delegitimization by one faction or another. The effect is cumulative. When Democrats argue that the Trump shooting was staged, they are borrowing the same rhetorical toolkit that Republicans used to discredit the 2020 election results. The methods are identical; only the targets differ.
This creates a situation where governing becomes impossible on the basis of shared fact. If significant portions of the electorate — whether Democratic or Republican — believe that elections are rigged, that assassination attempts are staged, that courts are politically captured, then the mechanisms for resolving disputes peacefully atrophy. Democracy requires a basic agreement about what happened. Not agreement on what it means, not agreement on what should be done — just agreement on what occurred. Without that foundation, every political conflict becomes existential, because there is no neutral arbiter to appeal to.
The media ecosystem makes this worse. Outlets that serve partisan audiences have incentives to amplify claims that confirm their viewers' priors, regardless of evidentiary quality. When a Manhattan Foundation poll shows nearly half of Democrats believing a conspiracy theory about a shooting, that number does not emerge from nowhere. It reflects years of coverage that treated every Trump-era controversy as potentially fraudulent, that raised questions about the credibility of law enforcement and intelligence agencies, that modeled suspicion of official accounts as a reasonable epistemic posture. The chickens have come home to roost, and they look exactly like the chickens the other side has been raising for just as long.
What Follows When Institutions Collapse
The political scientist's answer to institutional erosion is reform — strengthening guardrails, improving transparency, rebuilding trust through demonstrated competence. That answer is not wrong, but it assumes political actors want institutions to function. When institutions function, they constrain power. When they do not function, power operates without constraint. For politicians who have learned that attacking institutions pays electoral dividends, the rational move is to keep attacking them. Both parties have done this, at different times and in different registers, and neither has shown much appetite for the patient, unglamorous work of restoration.
Trump calling NATO a paper tiger is not a foreign policy statement. It is a domestic political signal — an indication that the alliance America built is subject to revision based on personal grievance rather than strategic calculation. The forty-seven percent of Democrats who believe the assassination attempt was fabricated are, in their own way, sending an equivalent signal: that official facts are negotiable, that what matters is what your side believes, that truth is a political resource to be deployed rather than a shared condition to be discovered. These two phenomena are not the same, but they emerge from the same soil. When the ground itself erodes, the structures built on it become unstable, whether they are military alliances or democratic consensus.
The most consequential question in American politics right now is not who wins the next election. It is whether there is enough remaining agreement about how elections work, how power transfers, how facts are established — enough shared institutional legitimacy — to make the outcome of an election matter. The evidence from the polling data, and from the rhetoric coming out of Washington, suggests that question is no longer rhetorical.
