"Cognitive surrender" leads AI users to abandon logical thinking, research finds

“Lowering the threshold for scrutiny”
Overall, across 1,372 participants and over 9,500 individual trials, the researchers found subjects were willing to accept faulty AI reasoning a whopping 73.2 percent of the time, while only overruling it 19.7 percent of the time. The researchers say this “demonstrate[s] that people readily incorporate AI-generated outputs into their decision-making processes, often with minimal friction or skepticism.” In general, “fluent, confident outputs [are treated] as epistemically authoritative, lowering the threshold for scrutiny and attenuating the meta-cognitive signals that would ordinarily route a response to deliberation,” they write.
Subjects with high trust in AI were more likely to be misled by faulty responses, while those with high “Fluid IQ” were less likely to be misled by the AI.

These kinds of effects weren’t uniform across all test subjects, though. Those who scored highly on separate measures of so-called fluid IQ were less likely to rely on the AI for help and were more likely to overrule a faulty AI when it was consulted. Those predisposed to see AI as authoritative in a survey, on the other hand, were much more likely to be led astray by faulty AI-provided answers.
Despite the results, though, the researchers point out that “cognitive surrender is not inherently irrational.” While relying on an LLM that’s wrong half the time (as in these experiments) has obvious downsides, a “statistically superior system” could plausibly give better-than-human results in domains such as “probabilistic settings, risk assessment, or extensive data,” the researchers suggest.
“As reliance increases, performance tracks AI quality,” the researchers write, “rising when accurate and falling when faulty, illustrating the promises of superintelligence and exposing a structural vulnerability of cognitive surrender.”
In other words, letting an AI do your reasoning means your reasoning is only ever going to be as good as that AI system. As always, let the prompter beware.

Academic Proof-of-Work in the Age of LLMs
Written quickly as part of the Inkhaven Residency . Related: Bureaucracy as active ingredient , pain as active ingredient A widely known secret in academia is that many of the formalities serve in large part proof of work . That is, the reason expensive procedures exist is that some way of filtering must exist, and the amount of effort invested can often be a good proxy for the quality of the work. Specifically, the pool of research is vast, and good research can often be hard to identify. Even engaging in research enough to understand its quality can be expensive. As a result, people look toward signs of visible, expensive effort in order to determine whether to engage in the research at all. Why do people insist only on reading research that’s published in well-formatted, well-written pa
How can Beijing attract top-tier Chinese AI professionals based abroad?
Beijing should shift its strategy and improve ways to attract and retain top Chinese AI professionals as America’s accelerating integration of artificial intelligence into military and national security systems puts such talent in a bind. As geopolitical tensions rise, many highly skilled Chinese researchers working at US tech and research institutions are confronting a painful dilemma, according to Dai Mingjie, a researcher at the Institute of Public Policy at the Guangzhou-based South China...
Anthropic says Claude subscriptions will no longer support OpenClaw because it puts an 'outsized strain' on systems
Why It Matters The decision by Anthropic to stop supporting OpenClaw for Claude subscriptions is significant because it highlights the challenges of integrating third-party tools with AI systems. According to a report from Business Insider, Anthropic cited the "outsized strain" that tools like OpenClaw put on their systems as the reason for this move. This strain is likely due to the additional computational resources required to support these tools, which can impact the overall performance and reliability of the AI system. The impact of this decision will be felt by users who rely on OpenClaw to enhance their experience with Claude subscriptions. OpenClaw's founder has already expressed disappointment, stating that cutting support would be "a loss." This reaction is understandable, given
