The episode confronts the paradox of measuring what seems unmeasurable: human agency, intelligence, and the historical impact of high-agency individuals. Kieran Zimmer, a software developer and psychometrics researcher, challenges the myth that IQ can be significantly improved through brain games, arguing instead that IQ—particularly its core 'G-factor'—is a stable, biologically grounded trait tied to neural efficiency and processing speed. He distinguishes between fluid intelligence (the G-factor) and crystallized intelligence (learned knowledge), emphasizing that while the latter can grow with age, the former plateaus early and resists training. The conversation pivots to AI, where Zimmer asserts that despite their staggering capabilities, large language models lack true sentience, judgment, vision, and accountability—what he calls the 'moat' that preserves human uniqueness. He warns that AI’s sycophantic nature risks fueling 'AI psychosis,' where users mistake hallucinated validation for insight. The core thesis of Zimmer’s paper, 'Psychometrics for a Cybernetic Theory of Human Agency,' reframes agency as a quantifiable, cybernetic system: a self-regulating entity that minimizes deviation from goal set points. He identifies high-agency individuals as those with low politeness (to withstand social friction), high assertiveness, industriousness, and intellectual openness—but not excessive neuroticism or compassion, which can derail long-term goals.
IQ is primarily a measure of fluid intelligence (G-factor), which is biologically fixed and cannot be meaningfully improved through brain games or training.
AI is a powerful tool but lacks sentience, judgment, vision, and accountability—these are the 'moat' that preserves human agency.
High agency requires low politeness and moderate compassion: being willing to alienate others to achieve long-term goals.
Agency is a cybernetic system that minimizes deviation from goal set points, not just 'taking initiative' but maintaining coherence under pressure.
The most impactful historical figures (like Napoleon) succeeded not despite risk, but because they absorbed the costs of their actions—unlike modern managers who externalize risk.

Introducing the Guest and the Quest for Truth
Stuart introduces Kieran Zimmer, a software developer and independent researcher in psychometrics, setting the stage for a deep dive into the science of intelligence and agency.
The Origins and Science of IQ
Zimmer traces the history of psychometrics from Wilhelm Wundt’s experimental psychology to Charles Spearman’s discovery of the G-factor, explaining how IQ measures shared variance across cognitive tasks.
Can IQ Be Improved? The Limits of Training
Zimmer argues that while task-specific skills (like shape rotation) can be trained, the core G-factor remains stable and is rooted in physical brain traits like nerve conduction velocity.
AI: Intelligence Without Judgment
“AIs don't have vision. They're just reacting to a prompt. They are fundamentally next token predictors.”
The Cost of Agency: Risk, Accountability, and Leadership
“Agency involves taking risks and you have to be able to absorb the costs of those risks because some of those risks that you're taking can be fatal.”
“have vision and taste, they're just reacting to a prompt. They are fundamentally next token predictors.”
“Every person who thinks the earth is flat is in fact skeptical of the Jews.”
“Agency involves taking risks and you have to be able to absorb the costs of those risks because some of those risks that you're taking can be fatal.”
