The Neuroscience of Decision-Making Under Stress

Regarding your sleep comments, wouldn't undiagnosed sleep apnea also have a similar impact?

I would say anything that interrupts sleep and doesn’t allow you to get a full night sleep with the cycles of deep, rem, light and awake at the normal benchmarks (for you that a sleep study doctor could tell you) could impact your capabilities.

If being awake for 18 hours creates a cognitive impairment equivalent to a 0.05 BAC, how might systemic sleep deprivation among attorneys impact their ethical obligations to provide "competent" representation under ABA Model Rule 1.1?

This is perhaps one of the most underexamined ethical questions in the legal profession. The research cited in this course that states approximately 18 hours of wakefulness can produce cognitive impairment comparable to a 0.05 BAC comes from sleep science literature. But the directional finding is consistent: sustained sleep deprivation meaningfully degrades judgment, memory consolidation, and decision-making quality. Under Rule 1.1, competence requires the "thoroughness and preparation reasonably necessary" for the representation. If an attorney's cognitive capacity is significantly impaired by sleep deprivation, there's a real argument that systemic overwork can be an ethics issue. Practically, this raises questions the profession hasn't fully answered: At what point does chronic sleep deprivation constitute a failure of competence? Do law firms have any institutional duty to guard against it? Here's what I do know: your firm isn't home with you at night. Owning your sleep is ultimately on you. I say that with full awareness of how hard that is when you're in the office until all hours. I remember those all-nighters. But advocacy starts with self-advocacy. Something as simple as "I want to bring the most value to this firm, and without enough sleep, I'm not able to do that" opens a conversation that benefits everyone. Note: I'm not a neuroscientist or ethics counsel. This answer reflects the research I explored in building this course. For formal ethics guidance, consult your state bar.

In the context of ABA Rule 3.5 (Impartiality and Decorum of the Tribunal), what is the ethically permissible way for an advocate to respond when a judge exhibits abusive or obstreperous behavior on the record?

Great question and one where the neuroscience in this course speaks directly to the challenge. Under ABA Rule 3.5, an advocate must maintain decorum even when a judge does not. Practically, that means: Make a clear record. Calmly note the behavior on the record without matching the judge's tone. Your composure becomes evidence. Request a recess if you need a moment to regulate. This is not weakness; it's strategy. Move for recusal if the behavior rises to bias or prejudice affecting a fair proceeding. File a judicial conduct complaint after the matter concludes, if warranted. What's relevant from this course: abusive judicial behavior is a high-stakes stressor that can trigger the exact amygdala-hijack response discussed, narrowing your thinking precisely when you need strategic clarity. Advocates who have practiced stress-regulation techniques are better equipped to respond professionally in the moment rather than reactively. Note: I'm not a neuroscientist, and this isn't legal ethics counsel… it's an answer grounded in the research explored in this course. For jurisdiction-specific ethics guidance, consult your state bar's ethics hotline.

What if you fall asleep while watching TV to relax? Does this sleep period get "credited" toward your bed sleep?

I’m not a sleep expert, but from my understanding of the research – the answer is “partially” but with significant caveats. My understanding is that “TV sleep” is typically fragmented and shallow – you get very little deep sleep or REM which are the most critical stages for memory consolidation, stress hormone regulation and physical restoration. The light and audio suppress melatonin and interrupt sleep cycling. You brain basically stays on alert as it’s processing the sensory input. Then if you move to bed, you’ve discharged the sleep pressure without completing a proper sleep cycle – which makes it harder to fall into deep sleep in bed. So you might feel like you slept, but you wake up feeling unrefreshed because you skilled the restorative sleep needed for that. So, it counts a little but it’s not great. The journey is yours, Marlo
