Engineering a clearer future.

The Philosophy

We structure scattered knowledge against primary sources and established scholarship. The more open a topic is to interpretation, the more we surface sources and limits — and we cross-link entries with tools and in-depth articles.

What we cover

• Mystic dictionaries: Saju (stems·branches·gods), 78 tarot cards, astrology, myth, dreams, oracle.
• Psychology & personality: The MBTI 16-type matrix and personality/relationship terms.
• Life & finance terms: Tax, investing, solar terms, holidays — everyday concepts, defined.

"The best way to predict the future is to engineer it."

Who writes this — our editorial desks

OIYO content is not written by an anonymous individual but by topic-specific editorial desks that verify against primary sources and public statistics. Each desk's remit:

• Editorial Desk The OIYO editorial desk researches money, law, lifestyle, and self-understanding topics against primary sources and public statistics. Every piece carries source notes and is reviewed on a regular cycle for accuracy and usefulness.
• Research Team The OIYO research team structures material from psychometric scales, statistics, and academic literature. We name both the popular framing and its scholarly limits, so each guide works as a tool for reflection rather than a verdict.
• Psychology Research Our personality content organizes widely used models — MBTI, Big Five, attachment theory — alongside the scales behind them. We treat types as a language for situational self-observation, not a fixed identity.
• Science Desk The OIYO science desk explains astronomy, physics, and everyday science with structure before memorization. We translate textbook concepts and current consensus into plain analogies, checked so simplification never distorts the facts.
• History & Culture Desk Our history and culture content presents myth, classics, and traditional thought from primary texts and established scholarship. The more open a topic is to interpretation, the more we surface sources and competing readings.

How we work — editorial principles

Every piece (1) checks facts against primary sources, official statistics, and academic literature; (2) states limits and disclaimers for sensitive topics like psychology and health; and (3) carries an updated date and is revised on a regular cycle when the topic changes. Our goal is to give you a basis to judge for yourself rather than a verdict.
