Here's the part of the show-trial story that should unsettle you most: it wasn't only the defendants who were persuaded. Sophisticated Western observers — a Pulitzer-winning correspondent, a US ambassador, seasoned reporters — watched the Moscow trials and came away believing them. They saw men confess to impossible crimes and concluded the men must be guilty.1
That is a second kind of dark persuasion, and it's easy to overlook because it happened to the audience rather than the accused. The show trials didn't just break the people in the dock. They fooled a good number of the people in the press gallery — and understanding how is its own lesson, because the credulous witness is a recurring figure in this whole history, right through to the age of fake news.
Walter Duranty was the New York Times's man in Moscow, and he believed the confessions. He explained them away with worldly sophistication: the defendants' self-incrimination came, he wrote, from "the stress of a guilty conscience" and "the semi-religious nature of Bolshevist fanaticism, which leads to breast-beating and cries of 'Mea maxima culpa.'"2
Read that and notice the move. Faced with men confessing to crimes they didn't commit, Duranty didn't reach for the obvious explanation (they were coerced). He reached for an exotic cultural one — these Slavic fanatics are just built for breast-beating confession. The exotic explanation let him take the confessions at face value while feeling sophisticated about it. His coverage was so bad that the Times itself, years later, called it "some of the worst reporting to appear in this newspaper." But the reassessment came far too late to help the victims.
One American reader, having absorbed Duranty's columns, wrote to a friend that he "could not doubt" the defendants were "mad dogs, criminal oppositionists, heretics, unbelievers." The propaganda had traveled: from the courtroom, through the trusted correspondent, into the reader, who now held the prosecutor's exact vocabulary as his own considered opinion.
Joseph Davies, the US ambassador to Moscow, also believed the trials proved genuine treason. And his reasoning is a small masterpiece of the way expertise can become a vulnerability rather than a defense. Writing to his daughter, Davies claimed that his many years as a lawyer qualified him to assess the validity of the testimony — and his lawyerly judgment was that the confessions were sound and the Kremlin's fears justified.3
His legal training, which should have made him skeptical, instead made him confident — confident enough to certify a fabrication. The career diplomat Charles Bohlen saw it clearly and was mortified: "I still blush when I think of some of the telegrams he sent to the State Department about the trial."4
This is the trap the credulous-witness pattern keeps springing: the observer's own competence becomes the thing that fools him. Davies trusted his ability to read testimony, so he trusted testimony that was scripted. The more sure you are that you can tell a real confession from a false one, the more available you are to a good enough performance.
The most instructive cases are the reporters who noticed something was wrong and talked themselves out of it anyway. Harold Denny, writing for the New York Times, described the defendants' behavior with real acuity: they "supplement their full confessions with eager testimony against themselves and against each other. They spring to their feet like bright pupils glad to show how much they know… these defendants do not testify like men coerced."5
He saw it. He registered the uncanniness — the too-eager self-incrimination, the bright-pupil performance, the wrongness of men marching toward a firing squad while volunteering their own guilt. And then he supplied a rationalization to smooth it over: "Perhaps it is part of the traditional Slavic-Oriental indifference to death." The same exotic-culture move as Duranty. Denny had the evidence of his own senses that these confessions were strange, and he neutralized it with a stereotype.
That is the precise anatomy of motivated credulity, and it's worth naming because it's not stupidity. Denny wasn't dumb; he was a professional observer who accurately perceived the anomaly. The failure came at the next step, where the anomaly got explained away rather than followed. The mind that has a comfortable story available ("that's just how those people are") will use it to dissolve the discomfort of the thing it actually saw. The show trials worked on the press gallery not by hiding the seam but by providing a ready-made explanation for it — and even the sharp-eyed reached for the explanation.
You are staging show trials, and you need the world to believe them. You cannot control foreign reporters directly, so you engineer their credulity structurally.
You make the confessions full and eager — not grudging but enthusiastic, defendants springing up to condemn themselves. Grudging confession looks coerced; eager confession looks sincere, and sincerity is what a distant observer reads as truth. You are betting that the very strangeness of eager self-incrimination will be explained away rather than investigated.
You rely on two allies you don't have to recruit. First, the sophisticated observer's need to feel sophisticated — he won't reach for the crude explanation (they were tortured), he'll reach for the worldly one (these fanatics just confess like this), because the worldly explanation flatters his cultural knowingness. Second, the expert's confidence in his own expertise — the lawyer who trusts his ability to read testimony will certify your script, because his skill has become his blind spot.
What tells you it's working is not that observers fail to notice the anomaly — the good ones will notice. It's that they narrate it away. When a sharp reporter writes "these defendants do not testify like men coerced" and then explains it with a stereotype instead of an investigation, your engineering of his credulity is complete. He has seen the seam and stitched it shut himself.
The evidence is the published record — Duranty's columns and the Times's later repudiation, Davies's letters and dispatches, Bohlen's memoir, Denny's dispatches — all documenting what these observers wrote at the time. We can read their credulity in their own bylines.
The tension is uncomfortable and Dimsdale doesn't fully close it: how much of this was honest error and how much was motivated? Duranty had reasons to stay in Stalin's good graces; Davies had a diplomatic interest in a functional relationship. So was the credulity a cognitive failure (the exotic-explanation trap) or a corruption (telling the sponsors what served them)? Probably both, in varying mixtures per observer — and that mixture is exactly what makes the pattern durable. Pure corruption would be easy to discount; pure error would be correctable. It's the blend — a genuine cognitive vulnerability lubricated by an interest in believing — that lets propaganda travel through trusted intermediaries into the general public.
This page is the audience-side companion to The Show Trial Confession Machine and Vyshinsky the Prosecutor. Those pages show the confession being manufactured and staged; this one shows it landing — completing its journey from the cell, through the courtroom, into the credulous correspondent, and out to the reader who ends up parroting Vyshinsky's "mad dogs" as his own opinion. The trial isn't finished when the defendant confesses; it's finished when the world believes him.
It converges powerfully forward with the book's final chapter on fake news. Dimsdale draws the line himself: the reporter who explains away the seam and the modern reader who accepts a preposterous rumor because it arrives from a trusted source are the same phenomenon. Duranty is Pizzagate's ancestor. The credulous intermediary — the trusted voice who launders a fabrication into belief — is the constant across ninety years; only the medium changed.
To behavioral-mechanics — Social Media as Scalable Coercion Architecture. The Duranty pattern — a fabrication laundered into belief by a trusted intermediary — is the mechanism social media industrializes. Where the show trials needed a Pulitzer-winning correspondent to carry the lie to the public, the platform needs only a shareable post from someone in your network. The insight the pairing produces: the credulous witness was always the load-bearing component of propaganda, and the internet's real innovation is removing the bottleneck. You no longer need to fool a few gatekeeping correspondents; you fool millions of small trusted intermediaries at once, each forwarding the fabrication to their own circle. The exotic-explanation trap and the expert's-blind-spot trap still operate — they're why 50–75% of adults rate fake headlines as credible — but now there's no Times to issue a repudiation years later, and no single byline to hold accountable. Duranty at least had a name and an employer that eventually blushed.
To psychology — Suggestibility Under Extreme Stress. The defendants were made suggestible by extreme stress; the observers were made credulous by something subtler — the comfort of a ready-made explanation and the confidence of their own expertise. The connection reveals a second, quieter channel of persuasion running parallel to the coercive one. The prisoner is broken into belief through debility and dread; the witness is eased into belief through a flattering narrative that resolves his discomfort. Same destination — accepting a fabrication as truth — reached by opposite roads, one paved with terror and one with self-regard. Coercive persuasion breaks the person inside the machine; motivated credulity seduces the person watching it, and the second is cheaper, scales further, and leaves no bruises to point to later.
Sharpest implication: The show trials persuaded not only the defendants but the press gallery — and the mechanism on the audience was motivated credulity, not coercion. The sharpest observers saw the seam ("these defendants do not testify like men coerced") and stitched it shut with a stereotype, because the mind with a comfortable explanation available will use it to dissolve the discomfort of what it actually witnessed. Expertise didn't protect the ambassador; it made him certify the fabrication. The trusted intermediary who launders a lie into public belief is the constant from Duranty to the algorithmic feed — only the bottleneck has been removed.
