情弱ほど損をする世界で生き残る方法【行動経済学×情報の非対称性】

The same product, the same performance, the same warranty. Yet, someone next door gets it for much cheaper—that's the invisible premium that those without information are unknowingly charged. This is the "information-poor premium." Insurance, smartphone plans, home equipment, used cars—why do people who don't have time to research end up paying more? And to what extent do sellers intend this premium? Using information asymmetry, search theory, shrouding (hidden added price), and anchoring as clues, we dissect the mechanism by which knowledge differences quietly translate into money. This isn't a story about "blaming the information-poor." We are all experts in some areas and laypeople in others. The moment we step into an unfamiliar field, everyone becomes information-poor—we will examine the very structure of that phenomenon.
