Big Brain Index or Big Hype?
Anthropic: Introducing The Conceptual Reasoning Index
Anthropic says it can score AI ‘deep thinking’—commenters say ‘sure, buddy’
TLDR: Anthropic launched a new test to rate how well AI handles complicated, hard-to-check ideas about the future and safety. The community reaction was brutally split: some see useful research, while others mocked it as a self-serving scoreboard and a shiny new marketing stunt.
Anthropic and Redwood Research just unveiled the Conceptual Reasoning Index, a new score meant to measure how well AI can handle big, messy questions with no easy right answer—think philosophy, future planning, and how to avoid AI disasters. On paper, it’s serious stuff: three tests, a public website, and a pitch that better “thinking” from AI could help humans manage the risks of more powerful systems. But in the comments, the mood was less standing ovation and more record-scratch skepticism.
The strongest reaction? A lot of readers simply did not buy the premise. One commenter hit the brakes at the opening line about AI helping us understand our situation, basically saying: hold on, maybe interrogate that idea first. Others instantly turned the benchmark into a meme, with one person dubbing it the “Trust Me Bro benchmark,” which pretty much tells you how much faith they have in a test for judging vague, hard-to-prove reasoning.
And then came the real drama: credibility politics. Critics side-eyed the fact that this is a benchmark Anthropic helped fund, while Anthropic also comes out looking great on it. That sparked the spiciest accusation of all: is this science, or premium marketing with extra steps? One user summed up the company’s weird fan-hate relationship perfectly: people love Anthropic’s models, but hate the surrounding “shenanigans.” Even the more measured skeptics asked a fair question: if AI scores are rising smoothly anyway, is this new scoreboard actually revealing anything new—or just adding another glossy number to the pile?
Key Points
- •Anthropic and Redwood Research introduced the Conceptual Reasoning Index (CRI), an aggregate benchmark for evaluating AI conceptual reasoning.
- •The article argues that many AI risk reduction tasks lack practical empirical feedback loops and require argument-based reasoning.
- •CRI is built from three benchmarks: LMCA, ACCoRD, and DTBench capabilities.
- •The CRI website, conceptualreasoning.ai, is intended to be updated as new models and benchmarks are released.
- •LMCA is described as a dataset of curated, expert-rated conceptual arguments with 560 position texts and 1,461 arguments across topics such as decision theory, philosophy, and advanced AI risk.
