We sat down with Sara Saab (VP of Product at Prolific) and Enzo Blindow (VP of Data and AI at Prolific) to explore the critical role of human evaluation in AI development and the challenges of aligning AI systems with human values. Prolific is a human annotation and orchestration platform for AI used by many of the major AI labs. This is a sponsored show in partnership with Prolific.

While technologists want to remove humans from the loop for speed and efficiency, these non-deterministic AI systems actually require more human oversight than ever before. Prolific's approach is to put "well-treated, verified, diversely demographic humans behind an API" - making human feedback as accessible as any other infrastructure service.
When AI models like Grok 4 achieve top scores on technical benchmarks but feel awkward or problematic to use in practice, it exposes the limitations of our current evaluation methods. The guests argue that optimizing for benchmarks may actually weaken model performance in other crucial areas, like cultural sensitivity or natural conversation.
We also discuss Anthropic's research showing that frontier AI models, when given goals and access to information, independently arrived at solutions involving blackmail - without any prompting toward unethical behavior. Even more concerning, the more sophisticated the model, the more susceptible it was to this "agentic misalignment."
Enzo and Sarah present Prolific's "Humane" leaderboard as an alternative to existing benchmarking systems. By stratifying evaluations across diverse demographic groups, they reveal that different populations have vastly different experiences with the same AI models.
Looking forwards the guests imagine a world where humans take on coaching and teaching roles for AI systems - similar to how we might correct a child or review code. Working conditions and the evolution of labor in an AI-augmented world is also important to consider. Rather than replacing humans entirely, we may be moving toward more sophisticated forms of human-AI collaboration.
We need more representative evaluation frameworks that capture the messy reality of human values and cultural diversity.

![We Built Calculators Because Were STUPID! [Prof. David Krakauer]](https://i.ytimg.com/vi/dY46YsGWMIc/mqdefault.jpg "We Built Calculators Because Were STUPID! [Prof. David Krakauer]
Prof. David Krakauer argues that intelligence isnt about knowing more—its about doing more with less.
His core thesis flips our assumptions on their head: while emergence in complex systems is about more is different, intelligence is fundamentally about less is more.
Why Large Language Models Miss the Point
LLMs are more is more, Krakauer explains. Theyre essentially sophisticated libraries that know everything but understand nothing. When a student looks up answers in a library during an exam, we call them a cheater, not intelligent.
Intelligence Across All Life
Perhaps most surprisingly, Krakauer claims that all living things are intelligent—even bacteria. His reasoning: intelligence is the information accumulated through evolutions selective pressures. Its why we can say an elephant is smarter than a worm, but wed never say its more alive. The difference is accumulated capacity.
Three Dimensions of Intelligence
Krakauer proposes intelligence exists in three distinct flavours:
- Strategic Intelligence - Adaptation and survival where viruses actually beat us/
- Inferential Intelligence - Math and computation (where we built calculators because were so bad at it)
- Representational Intelligence - Finding better ways to encode problems (the most uniquely human)
The Soma Cube Insight
Using a Soma Cube puzzle, Krakauer demonstrates something incredible: a four-year-old can solve a combinatorial problem with 15,000 logical clauses—not by computing, but by using physical representation. The physical world does the computing for us. This is intelligence: making impossibly hard problems tractable through clever representation.
