Introduction and Speaker Context
📌 The speaker introduces the next speaker, referred to as "Docdes" (Dr. Riu Hasan), a neurosurgeon and the speaker's mentor since college.
🎤 The preceding discussion touched upon social intelligence and the concept of being intelligent yet annoying.
🤔 The speaker humorously admitted to realizing he was annoying only after turning 40 and subsequently working hard (though not entirely successfully) to change that behavior.

Critique of the Book on Rationality
🤯 The book being discussed is deemed "very heavy" and academic, resembling a six-semester textbook on human brain function.
😲 The speaker claimed to be a fast reader, consuming 250 pages in under one minute, but still found the book's prologue and Chapter 1 demanding due to complex charts and data.
🚫 He joked that 99.9% of readers would not want to read the entire book, suggesting those who enjoy it are "strange," similar to the authors.

Human Cognition: Emotion vs. Rationality
🧠 Approximately 99.9% of human decisions are driven by emotional decisions, not rational ones (e.g., walking, driving established routes).
⚽ Examples cited include athletes (football players training for 8-10 hours) and badminton players responding to shuttlecocks within 50 nanoseconds, all relying on ingrained emotional/subconscious recording rather than conscious rational thought.
🛑 While rational thinking is necessary (e.g., for designing a nuclear reactor), it is less frequently used; non-scientific thinking has prevailed for thousands of years, suggesting it is sometimes more "beneficial" for survival.

Social Intelligence and Emotional Control
✨ Social intelligence is described as the next level of emotional intelligence, both being skills that require training.
🤯 The common teaching that "nothing is impossible" is fundamentally irrational and counterproductive to genuine rational thought, as many things *are* impossible (e.g., rolling an eight on a standard die).
😇 Non-rational thinking provides comfort; for instance, attributing lightning to an angry God was a comforting explanation for 5,000 years until science provided the rational explanation (positive and negative cloud interactions).

Emotional Intelligence in Practice
🛑 Emotional intelligence is not about suppressing emotion, but preventing emotions from too frequently hijacking rationality.
🍵 An example of good emotional intelligence is simply enjoying food (like eating a *melinjo*) without over-analyzing its botanical classification (monocotyledon vs. dicotyledon).
🇯🇵 The actions of Japanese citizens following the Japan Airlines accident demonstrate high societal emotional intelligence: following directions immediately (a doctrine ingrained since childhood) ensures societal order, despite individuals sometimes being prone to being "annoying" ("individual njelei").

Key Points & Insights
➡️ Truly rational thinking is a trainable skill; if not trained from childhood, people will default to non-rational thinking patterns.
➡️ Prioritize emotional regulation so that emotions do not constantly override rational assessment, exemplified by avoiding analyzing every trivial activity.
➡️ Societal excellence (like in Japan) is often achieved through rigorous training in social norms (like queuing or apologizing), which involves training the brain *not* to feel overly important.
