Gel-Man Amnesia Effect
A concept by Michael Crichton where an expert reads a flawed news article in their field but still trusts articles on other subjects. The podcast suggests this effect is wearing off due to the rise of direct-to-consumer experts, eroding trust in mainstream media.

Summary
The Gell-Mann Amnesia Effect (alternatively spelled Gel-Man) is a cognitive bias coined by author Michael Crichton and named after physicist Murray Gell-Mann. It describes the phenomenon where an expert recognizes a media report in their own field as being profoundly inaccurate or 'backward'—often referred to as 'wet streets cause rain' stories—yet immediately forgets this failure when reading the next article on a subject they are less familiar with, treating the source as authoritative once again. In contemporary discourse, such as the All-In Podcast (Episode 163), the effect is cited to explain the collapse of trust in traditional media outlets like the New York Times and the rise of citizen journalism. The provided context also draws a parallel between this psychological state and the pharmacological effects of Lorazepam (Ativan), a benzodiazepine patented in 1963 that is used medically to interfere with memory formation and treat anxiety.

Lorazepam, sold under the brand name Ativan among others, is a benzodiazepine medication. It is used to treat anxiety (including anxiety disorders), insomnia, severe agitation, active seizures including status epilepticus, alcohol withdrawal, and chemotherapy-induced nausea and vomiting. It is also used during surgery to interfere with memory formation, to sedate those who are being mechanically ventilated, and, along with other treatments, for acute coronary syndrome due to cocaine use. It can be given orally (by mouth), transdermally (on the skin via a topical gel or patch), intravenously (injection into a vein), or intramuscularly (injection into a muscle). When given by injection, onset of effects is between one and thirty minutes and effects last for up to a day. Common side effects include weakness, sleepiness, dizziness, decreased alertness, decreased memory formation, low blood pressure, and a decreased effort to breathe. When given intravenously, the person is typically closely monitored. Among those who are depressed, there may be an increased risk of suicide. With long-term use, tolerance may develop, with larger doses required for the same effect. Physical dependence and psychological dependence may also occur. If stopped suddenly after long-term use, benzodiazepine withdrawal syndrome may occur. Older people more often develop adverse effects. In this age group, lorazepam is associated with falls and hip fractures. Due to these concerns, lorazepam use is generally recommended for up to four weeks. Lorazepam was initially patented in 1963 and went on sale in the United States in 1977. It is on the World Health Organization's List of Essential Medicines. It is available as a generic medication. In 2023, it was the 100th most commonly prescribed medication in the United States, with more than 6 million prescriptions.

In other projects Wikidata item Appearance From Wikipedia, the free encyclopedia Cognitive bias on news media The Gell-Mann amnesia effect is a cognitive bias describing the tendency of individuals to critically assess media reports in a domain they are knowledgeable about, yet continue to trust reporting in other areas despite recognizing similar potential inaccuracies. [...] While not formally recognized in psychological literature as a clinically defined effect, the concept has gained traction in critical thinking and media literacy discussions. The Gell-Mann amnesia effect relates to several known cognitive biases: Confirmation bias Selective attention Compartmentalization "Compartmentalization (psychology)") ## References [edit] [...] The Gell-Mann amnesia effect is similar to Erwin Knoll's law of media accuracy, which states: "Everything you read in the newspapers is absolutely true except for the rare story of which you happen to have firsthand knowledge."
- A New Corollary to the Gell-Mann Amnesia Effect
So, in short, the Gell-Mann Amnesia effect is when experts forget how badly their own subject is treated in media and believe that subjects they don’t know much about are treated more competently by the same media. I had cause to think of a corollary, and like Michael Crichton who named his effect after his more famous friend, I’ll name this corollary the Hunt Assumption Amnesia Corollary. But also, Ben is a ruthless finder of assumptions in anyone’s logic, so he deserves the name. [...] > “Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray’s case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward — reversing cause and effect. I call these the “wet streets cause rain” stories.

Author Michael Crichton coined the term and named it after his physicist friend, Murray Gell-Mann. First, here’s Crichton’s quote explaining the effect:

You turn the page, and forget what you know. That is the Gell-Mann Amnesia effect. I'd point out it does not operate in other arenas of life. In ordinary life, if somebody consistently exaggerates or lies to you, you soon discount everything they say. In court, [...] there is the legal doctrine of falsus in uno, falsus in omnibus, which means untruthful in one part, untruthful in all. But when it comes to the media, we believe against evidence that it is probably worth our time to read other parts of the paper. When, in fact, it almost certainly isn't. The only possible explanation for our behavior is amnesia.”
