Most of the performance psychology you have been sold did not survive a harder test. Under Pressure is the volume of The Trader's Mind that says so out loud — and then hands you the short, real list of what did survive, which is worth more precisely because it is real. This volume separates, on the page and on purpose, what held from what did not. The performance findings that survived replication — the explicit-monitoring account of choking, the parts of stress inoculation that hold, flow read as a framework rather than a switch — are taught as load-bearing. Then an entire part is given to the famous ideas that did not survive: ego depletion, power posing, grit, the strong growth-mindset claim, trait mental toughness, the inverted-U "law," and the popular over-extension of the ten-thousand-hour rule — each handed to you in the same passage as the meta-analysis or replication that undercut it, with deliberate practice the one correctly-scoped survivor. The book states plainly that within performance psychology proper the broken findings outnumber the survivors, and that the volume's robust spine is carried by the stress-physiology evidence: allostatic load, the acute-stress shift in risk, the cost of sleep debt, the line between a gambling disorder and disciplined trading, and the burnout construct. The clinical material is strictly educational — no screen, no checklist, no diagnosis — and routes disorder-adjacent signals to a licensed clinician. It closes with a short recalibration toolkit that takes no move from a finding that failed to replicate. Standalone-readable. What you will learn: - Which celebrated performance findings broke under replication — and the evidence that broke them - The explicit-monitoring mechanism behind choking, and what it implies under live size - What stress physiology actually does to risk-taking, decision quality, and sleep-deprived judgment - The honest line between disciplined active trading and a behavioral-addiction profile - Why the surviving spine of this field is the stress body, not the famous slogans - A pressure self-audit and recalibration practice built only on what survived Who this book is for: Serious retail and aspiring-professional futures traders who have been sold "grit," "flow," and "mental toughness" and want to know which of it is real.
