How Fear and Fatigue Degrade Human Judgment by Jordan

How Fear and Fatigue Degrade Human Judgment by Jordan - October 2026 Scholarship Essay

The first time I watched fear hijack a brilliant mind, I was hanging off a granite wall in Yosemite. My climbing partner, an engineer who could do thermodynamics in his head, froze three hundred feet off the deck. His hands shook. He kept mumbling about the anchor, a piece of gear I knew was bombproof. His body was doing exactly what human bodies do when the amygdala takes the wheel: narrowing his attention, flooding his blood with adrenaline, and degrading the very prefrontal cortex he needed to assess risk clearly.

That moment planted the research question that has driven my last fifteen years of work: how do fear and fatigue degrade human judgment in high-consequence environments, and can we train people to think clearly anyway?

I came at the question from an unusual angle. I am a trained behavioral scientist and social psychologist, but I am also a rock climber and ultra-endurance athlete. Early on, I realized that the alpine world is a perfect field laboratory. On a big wall, the variables that confound laboratory experiments disappear. Motivation is absolute. Stakes are real. Decisions matter in a way no lab scenario can replicate.

I started keeping meticulous notes on what happened to my own thinking on long routes: how sleep deprivation made simple route-finding feel impossible, how fear compressed my sense of time, how exhaustion made me irrationally certain about bad decisions. What began as field notes became a systematic investigation. I started designing informal experiments on myself and with climbing partners. We tested simple interventions at altitude: structured breathing protocols before committing moves, checklists borrowed from aviation, forced pauses to reassess when fear spiked. Some worked. Most failed, and the failures were the most instructive. I learned that willpower is a terrible strategy under pressure. Systems beat motivation every time.

That insight deepened my understanding of the subject far beyond what textbooks had given me. In my neuroscience training, I had learned about the amygdala and prefrontal cortex as diagrams. On a wall at 2 a.m., I learned them as lived experience.

The research question expanded: it was no longer just about climbing. Surgeons, pilots, first responders, soldiers, anyone who makes consequential decisions while frightened and exhausted faces the same biology I was studying on rock.

This is why I am pursuing the ALM in Psychology through Harvard Extension School. I want to take fifteen years of field observation and put it on a rigorous scientific foundation. The questions that began on a cliff face, how fear distorts judgment, how fatigue erodes decision quality, how to build systems that preserve clear thinking under pressure, deserve real answers backed by real science.

What started as curiosity about my own shaking hands became a life's work: understanding human behavior so we can reduce suffering and help people perform when it matters most.
