なぜマウントで眠れなくなるのか【社会心理学×進化心理学】

"I didn't mean any harm." For some reason, I can't sleep on nights when someone says that to me. Why do those words, the ones that made me feel superior, keep coming back to me in bed? This book explores this mystery from two perspectives: "social comparison theory" from social psychology and "hierarchy and survival" from evolutionary psychology. ■ Table of Contents 0:04 Introduction | Sleepless Nights 2:42 Chapter 1 | The Invisible Measuring Stick 6:11 Chapter 2 | Hierarchy as a Lifeline 10:12 Chapter 3 | The Alarm That Rings at Night 13:49 Chapter 4 | The Echoes of Territory 17:14 Epilogue | The Forest at Dawn *Timestamps are calculated taking into account the length of the eye-catching image and title card.

Festinger's social comparison theory and how upward comparison lowers mood and self-esteem. Data showing that social media is a "flood of upward comparison." The evolutionary reasons why the brain treats a drop in rank as a "danger to life," and the mechanism by which alarms continue to sound at night. The mismatch between Dunbar's number and social media, and the perspective that those who "put down" are also driven by the same brain. ■ Main References Leon Festinger (1954) "A Theory of Social Comparison Processes," Human Relations, 7(2) ── Proposed social comparison theory.
