5 decks to anchor the key definitions and reference points of general knowledge: global institutions and organizations, fundamental economic concepts, political and institutional concepts, everyday scientific notions, orders of magnitude. Fundamentals for everything else.
Each deck covers a fundamental domain of general knowledge. These decks are dense with key concepts — many notions in few cards. Recommended as a foundation before tackling the more advanced thematic clusters.
UN, IMF, World Bank, NATO, WTO, G7, G20, International Criminal Court — who does what, who decides how, who funds whom. The organizations that structure global governance and whose decisions appear in every news bulletin.
View deck →GDP, inflation, unemployment, trade balance, monetary policy, interest rates, sovereign debt — the macroeconomic concepts that newspapers discuss daily and that many citizens understand only vaguely. An essential foundation for reading economic news.
View deck →Liberal democracy, rule of law, federalism, separation of powers, populism, sovereignty, secularism, constitution — the concepts of political vocabulary that allow understanding debates on systems of government and their crises.
View deck →DNA, cell, atom, electromagnetic waves, entropy, placebo, virus vs bacterium, metabolism — the fundamental scientific notions every adult should understand to read science and health news without getting lost in jargon.
View deck →World population, GDP of major powers, CO2 emissions, speed of light, cosmic distances, geological ages — the orders of magnitude that prevent you from being manipulated by numbers out of context and that let you quickly verify the coherence of information.
View deck →Essential general knowledge isn't what you don't know — it's what you think you know. Most educated adults have an approximate definition of GDP, a vague idea of what the IMF does, a fuzzy notion of what liberal democracy means. These approximations suffice day-to-day until they don't.
Fundamentals need to be precise to be useful. The difference between correlation and causation, between public debt and deficit, between virus and bacterium — these distinctions seem trivial until they change your understanding of an entire subject. Spaced repetition anchors these definitions precisely, until they're available under pressure.
These 5 decks are not an encyclopedia. They're 79 cards selected to cover the most frequent blind spots in general knowledge: the organizations cited without really knowing what they do, the economic concepts used approximately, the scientific notions that get confused. A solid foundation for everything else.
The 'International Institutions and Organizations' deck is the recommended entry point. Knowing what the UN, IMF and WTO do gives context for the subsequent decks on economic and political concepts. These 15 cards are dense but fundamental.
The value of these decks isn't learning what you don't know — it's sharpening what you think you know. Many concepts will be recognized but poorly defined. The FSRS algorithm identifies exactly these grey areas and works on them until the definition is precise and available under pressure.
These 5 fundamentals decks are designed as a foundation before more advanced thematic clusters: geopolitics, history, science, economics, critical thinking. Once fundamentals are anchored, these advanced topics become much more accessible and cross-domain connections emerge naturally.
These 5 decks cover multi-domain fundamentals — the basic concepts that appear across all subjects. The other clusters (geopolitics, history, science, economics) deepen each domain with 5 to 6 dense decks. Starting with essential general knowledge lays a foundation that makes the advanced clusters much more accessible.
Yes. Competitive civil service exams, business school admissions and journalism programs systematically include fundamental general knowledge questions: international institutions, basic economic concepts, scientific notions. The memia decks cover exactly these angles. They're also useful for university entrance exams and professional job interviews.
Absolutely. Many adults want to consolidate their general knowledge fundamentals to be more comfortable in professional discussions, public debates, or simply for personal satisfaction. These 5 decks represent the minimum foundation for a well-informed 21st-century adult.
Yes — the selectivity is deliberate. These decks cover the 79 most fundamental concepts, not 790. The goal isn't comprehensiveness but solidity of foundations. A precise definition of these 79 concepts is worth more than a fuzzy knowledge of 500. They serve as a foundation for denser thematic clusters.
Yes, and it's even recommended. Doing 'Essential General Knowledge' in parallel with 'Geography and Geopolitics' or 'World History' creates cross-domain connections that reinforce anchoring in both. The FSRS algorithm automatically manages review sessions for each deck independently.
First deck accessible without a credit card. In 15 minutes a day, you build the fundamentals that give meaning to all other subjects.
