Claims from this post (5)
In the order they appear in the post. Each quotation is the speaker’s words in this post. A label such as “Supported” or “Can’t be checked” is the claim’s current assessment; its page has the evidence and the reasons.
Assessment: SupportedSaid
“In my 2023 Senate testimony, in a 2023 essay here, and in my 2024 book Taming Silicon Valley, I strongly advocated for a system of preflight testing for AI models deployed at large scale, ideally mandatory, transparent and independent, modeled perhaps on the FDA’s analysis of costs and benefits for pharmaceuticals.”
What we tested: In his 2023 Senate testimony, a 2023 essay, and his 2024 book Taming Silicon Valley, Marcus strongly advocated preflight testing for AI models deployed at large scale, ideally mandatory, transparent and independent, perhaps modeled on the FDA's cost-benefit analysis for pharmaceuticals.
What happened: Marcus explicitly recommends FDA-style review before widespread deployment. Elsewhere in this transcript he calls for independent scientists and qualified external reviewers, and a licensing safety case weighing benefits against harms. (Tech Policy Press, )
Assessment: Can’t be checkedSaid
“As recently as a few months ago, getting the US to implement preflight testing seemed hopeless, given a great hostility to AI regulation that was then widespread in Washington.”
What we tested: As recently as a few months before July 2026, getting the US to implement preflight testing seemed hopeless, given great hostility to AI regulation that was then widespread in Washington.
Assessment: SupportedSaid
“But the Mythos moment got The White House to consider and in fact implement preflight testing to some degree (though not with the transparency or independence or breadth or mandatoriness that I believe to be critical).”
What we tested: The Mythos moment caused the White House to implement AI preflight testing to some degree, though without the transparency, independence, breadth or mandatoriness Marcus considers critical.
What happened: The White House set up voluntary pre-release review of frontier models, and the order explicitly rules out mandatory preclearance. This matches 'to some degree' and 'not mandatory'. (Infosecurity Magazine, )
Assessment: Can’t be checkedSaid
“it cannot be just the government and big tech companies that make these decisions, particularly because of the potential for conflict of interest in a time in which the US government is contemplating take a stake in AI companies.”
What we tested: It cannot be just the government and big tech companies that make AI preflight testing decisions, particularly because of the potential for conflict of interest while the US government is contemplating taking a stake in AI companies.
Assessment: Can’t be checkedSaid
“The FINRA model that he suggests is excellent, and the world will be a better place if it is implemented, with transparency and independence.”
What we tested: The FINRA model Hassabis suggests is excellent, and the world will be a better place if it is implemented with transparency and independence.
Held from this post (2)
These records did not pass every check, so nothing about them is published. Held is not a finding.
- The two reviews reached different assessments. Our reading, not assessed: After the 2023 Senate hearings nothing happened on AI preflight testing, and the policy climate changed markedly when Trump took office.
- The two reviews read the claim differently
