ADVICE

Use AI To Spot Shifts Then Apply Human Judgement

Use AI to detect emerging patterns quickly, then decide whether the move reflects a real fundamental change or market panic.
Fletcher: let AI flag shifts and then apply human judgment to classify them as structural or emotional.

INSIGHT

Intelligence Is Fast Effective Planning

Human brains evolved to act and invent plans (stories) rapidly; intelligence equals effective planning and fast plan-updating.
Fletcher says smart people act faster, their plans succeed more, and they pivot quickly when plans fail.

ADVICE

Match Plan Novelty To Market Novelty

Match the novelty of your plan to the novelty of the environment: use off-the-shelf plans when stable and innovate rapidly when volatility rises.
Monitor your emotions as a signal: fear/aggression means your planning rate lags the environment.

Hedgeye Founder and CEO Keith McCullough sits down with Primal Intelligence author Angus Fletcher for a Real Conversation that goes straight to the source of performance: how the human mind actually works under uncertainty.

Keith has mentioned Primal Intelligence multiple times on The Macro Show and in The Early Look because the book challenges something most investors take for granted — that better logic automatically leads to better outcomes. Fletcher argues that human intelligence is not primarily built on cold calculation. It is built on narrative, imagination, adaptive thinking, and the ability to simulate possibilities before they happen. In other words, the very capabilities required to navigate volatile markets.

Markets are complex adaptive systems driven by human behavior and shifting expectations. You cannot spreadsheet your way through every inflection point. Success requires pattern recognition, dynamic risk management, probabilistic thinking, and the discipline to update without ego. Fletcher’s work explains why some investors thrive under pressure while others freeze.

In this conversation, Keith and Angus will explore how story-based cognition shapes decision-making, why imagination is essential for forecasting, and how investors can strengthen their ability to adapt during drawdowns and regime shifts. At a time when algorithms and AI dominate headlines, this discussion focuses on the distinctly human edge — the mental frameworks that drive conviction, resilience, and long-term performance.
