McLaughlin has closed his kerrison rongeur bone-biting instrument an estimated 2 million times, requiring total focus on every single bite to avoid damaging a nerve.

Lewis presses McLaughlin on how surgeons prepare for worst-case scenarios without spiraling into rumination. McLaughlin's answer is rooted in volume: where Anders Ericsson said 10,000 hours makes an expert, neurosurgery requires 50,000 hours of training plus another 50,000 of career practice. He brings out his kerrison rongeur — a bone-biting instrument he estimates closing 2 million times — to make a physical point about focus: every single bite demands total present-moment attention, because a millimeter of inattention can turn bone removal into nerve damage. His rule for West Point cadets crystallizes the principle: 'If you're casual, you create a casualty.'
The iRISE protocol — Identify, Reject first impulse, Inventory alternatives, Stabilize and re-Evaluate — is McLaughlin's systematic framework for managing black swan moments in surgery and life.
When everything goes wrong mid-surgery, the worst thing you can do is what feels natural. McLaughlin's iRISE protocol — Identify, Reject first impulse, Inventory alternatives, Stabilize, re-Evaluate — is a replicable framework for any high-stakes crisis.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
