Stress and Performance Science
The biology and psychology of stress, performance, and human limits — research that underpins Jason's coaching, writing, and personal philosophy. The central finding cuts against decades of popular health messaging: stress is not the enemy of performance. The belief that stress is harmful is. Two interconnected bodies of science extend from this insight: the first explores how mindset shapes the body's hormonal stress response, with direct consequences for health, behavior, and resilience; the second maps the physiological levers — deliberate practice, sleep, visualization, and nutrition — that determine how far a person can actually develop. Together they form a coherent picture of what performance requires and what gets in the way.

stress-mindset-science — How Mindset Shapes the Stress Response
The science behind why how you think about stress changes what stress does to your body. Covers Kelly McGonigal's reframe of stress as the experience of pursuing meaningful goals, the DHEA-to-cortisol growth index as a biomarker of performance under pressure, behavioral divergence by mindset, counter-intuitive trauma findings, the challenge response and tend-and-befriend modes, and the psychology of expectations, conviction, and confidence. The core argument: mindset interventions are not soft personal-development reframes — they produce documented hormonal and behavioral changes that compound over time.
performance-optimization — Practical Levers for Building Capability
The physiology of skill acquisition and peak performance. Covers Ericsson's deliberate practice framework and mental representations, the myelination mechanism underlying skill acquisition, the evidence on sleep as a performance variable (elite violinists averaged 8h36m per night), visualization science including power posing and elite gymnasts' two-stage mental rehearsal protocol, and the nutrition and physical health factors that make the body a better performance instrument. The core argument: performance is built through specific, tractable practices — not talent, not grinding, not willpower.
