Theory Briefing

  • Nitrogen narcosis and high-pressure nervous syndrome can cause hallucinations and violent outbursts in deep-sea divers, blurring the line between diver and danger.
  • The phenomenon illustrates how environmental stressors can override rational decision-making, a core concept in stress-inoculation and cognitive load theory.
  • Cases discussed show that even trained professionals are not immune — expertise offers little protection when brain chemistry is chemically altered by depth pressure.
