🧠 Everyday Dilemmas: 'Decision Fatigue' and Neuroscience
From the moment we open our eyes in the morning until we fall asleep at night, we are constantly standing at crossroads of choices. According to neuroscience research, an adult makes an average of about 35,000 big and small decisions a day. In this process, our prefrontal cortex consumes glucose very rapidly, eventually reaching a state of cognitive overload. Psychology refers to this symptom as 'Decision Fatigue'.
When trapped in a state of decision fatigue, the brain tries to conserve energy by avoiding extreme choices, maintaining the status quo, or making impulsive/irrational choices. The reason Apple founder Steve Jobs or Meta's Mark Zuckerberg wore the exact same clothes every day was to save the hassle of choosing from the closet—a sort of 'unconscious brain energy saving system' to reserve energy for far more imperative business decisions. Even a seemingly trivial dilemma like "What should I eat for lunch today?" can be a primary culprit devouring your brain's precious energy.
💡 Carl Jung's Psychological Types: Cognitive Functions Govern Consumption Behavior
Looking into psychologist Carl Jung's theory of psychological types, which serves as the foundation of MBTI, every individual has fundamentally different methods of perceiving information from the external world (Sensing, Intuition) and judging it (Thinking, Feeling). This is directly tethered to your consumption behavior—the decision of 'what to eat and which restaurant to go to'.
📊 Restaurant Selection Algorithm by MBTI Cognitive Functions
Extroverted Sensing (Se) Dominant - ESTP, ESFP
They vigorously seek intense aesthetic and visual experiences that directly stimulate the five senses. No matter how delicious the dish is, if it's not visually appealing or the restaurant vibe is too heavy, they tend to evade it. They derive sheer satisfaction from trendy "hot places" perfect for SNS authentication shots, or live-fire teppanyaki and barbecue cooked instantly on the spot.
Introverted Sensing (Si) Dominant - ISTJ, ISFJ
They rely profoundly on direct past experiences and memories. To them, challenging a brand-new, unverified restaurant poses a severe 'Risk'. They feel utmost comfort in regular diners with an unchanging taste, clean boundaries, secured reviews, longstanding mom-and-pop restaurants, or reputable franchises. For them, 'cost-effectiveness' paired with 'stability' makes up the unparalleled value proposition.
Extroverted Intuition (Ne) Dominant - ENTP, ENFP
They abhor being confined in a frame and strongly prefer the unknown. Endowed with tremendous curiosity, they are intensely attracted to completely novel menus, unique fusion dishes, or cuisines using unfamiliar exotic spices (e.g., Indian curry, Mexican, Middle Eastern). Even when selecting a restaurant, they perpetually seek variation, searching for entirely different categories from what they had yesterday.
Introverted Intuition (Ni) & Thinking (T) Type - INTJ, ENTJ
They are inclined to achieve maximum efficiency and purpose with minimum cost (time/money). Since they often regard dining as a mere 'energy recharging' protocol, they favor eateries offering perfectly balanced nutrients or serving food rapidly without entangling their daily itinerary. However, if a restaurant passes their astronomically high standards and qualifies as a 'masterpiece', they exhibit a dual nature of spending time and money unsparingly.
