- Scaled AI models show surprising creativity but still face issues like transfer and interpretability limitations.
Rethinking AI Intelligence and How We Measure It
Recent discussions highlight a key question: Are we truly understanding AI’s intellectual abilities? When a large language model (LLM) answers a question, does it reason like humans? Or is it just generating plausible-sounding text without genuine understanding? This distinction affects how much we trust AI’s decisions, how closely we need to supervise it, and what impacts it will have on society.
Melanie Mitchell from the Santa Fe Institute points out that we lack reliable ways to measure what AI truly knows. She calls AI an “alien intelligence” because it operates through unfamiliar mental processes. Mitchell suggests we borrow methods used in developmental psychology and comparative psychology—studies of babies and animals—to better examine AI’s cognition. These approaches could help us understand whether AI systems simulate human thought or possess something fundamentally different. Their conversation explores interpreting AI’s inner workings, recent breakthroughs like solving math problems, and lessons from the early 1900s about evaluating machine intelligence.
How Our Notions of Intelligence and Understanding Are Changing
Most of us accept that AI systems are “black boxes”—they work but we can’t see exactly how. Mitchell questions whether our own brains are less mysterious than we think. Neuroscience and psychology have tools to analyze human and animal minds, but these methods are often separate from AI research. Historically, AI aimed to mimic human cognition using direct programming, but the focus shifted to neural networks trained on vast amounts of data. This shift means AI now learns differently from how humans and animals develop intelligence.
The debate over testing AI often involves benchmarks, like math problems or language tasks. Mitchell notes that AI models can excel in specific areas but struggle to transfer those skills to different tasks. For example, solving one math problem doesn’t guarantee understanding how to solve similar, related problems. She points out the importance of careful experimental design and replication, referencing the story of Clever Hans, the horse that appeared to do math but was actually reading social cues. This highlights the need for control tests to prevent misleading conclusions about AI capabilities.
Mitchell proposes six principles for better understanding AI cognition, including avoiding human-like biases, developing robust tests, probing AI systems’ inner structures, and analyzing failures. She emphasizes that understanding AI’s true abilities requires humility and rigorous science, recognizing that much of what appears impressive may be superficial. These efforts are crucial as AI continues to evolve and shape technology, science, and society.
