5 decks to anchor critical thinking tools: identify fallacies in context, understand the biases that distort information, spot misinformation, read numbers methodically, verify sources. Spaced repetition turns theoretical knowledge into reflexes.
Each deck covers a domain of critical thinking. Recommended in the order presented for logical progression — each deck builds on the previous ones.
Ad hominem, straw man, slippery slope, false dilemma, appeal to tradition, cherry picking — the 35 most common fallacies in public debate. Learning to name them is learning to spot them when they appear before you.
View deck →Confirmation bias, halo effect, authority bias, anchoring, availability bias — the mechanisms that distort our information processing without our realizing it. Knowing these biases doesn't eliminate them, but naming them helps build awareness.
View deck →Mechanisms of false information spread, distinction between disinformation / malinformation / misinformation, filter bubble effects, conspiracy theory vs real conspiracy, emotionalization of information. Understanding why misinformation works to better protect yourself.
View deck →Mean vs median, correlation vs causation, sampling bias, Y-axis manipulation, misleading percentages, effect size — the classic traps in data communication and the reflexes for detecting them.
View deck →SIFT (Stop, Investigate, Find better sources, Trace), lateral reading, reverse image search, source evaluation, institutional fact-checking. The operational methods for verifying information before sharing or trusting it.
View deck →Most educated people know that cognitive biases and logical fallacies exist. Confirmation bias, ad hominem, misinformation — these concepts circulate widely. The problem: knowing a bias theoretically doesn't protect you. Under the pressure of a debate or faced with emotionally charged information, critical reflexes disappear.
Critical thinking is a practical skill, not a body of knowledge. It develops through training, not reading. Spaced repetition creates exactly this training: each flashcard presents a fallacy, a bias or a statistical trap in a concrete context, until recognition becomes automatic.
These 5 decks won't make you infallible — no one fully escapes their own biases. But they give you precise vocabulary to name what you detect, and reflexes anchored enough to slow down before accepting information or an argument too quickly.
The 'Logical Fallacies and Rhetorical Manipulation' deck is the recommended entry point. Fallacies are the most identifiable manipulations once you know how to name them. Starting here gives practical vocabulary that subsequent decks will deepen.
These decks are built around concrete cases: a debate excerpt, a newspaper headline, a truncated graph. The FSRS algorithm re-presents these cases precisely when your recognition starts to weaken — anchoring detection reflexes, not abstract definitions.
The real test of these decks isn't your score in memia — it's the next time you read an article with a misleading chart, attend a debate with an ad hominem, or receive emotionally charged information. With these reflexes anchored, you naturally slow down before reacting.
Yes. Critical thinking is a component evaluated in many competitive exams: journalism schools, political science programs, civil service exams and some business schools that include synthesis or debate components. These decks cover the tools most frequently mobilized: identifying fallacies, reading charts, evaluating sources.
A cognitive bias is an involuntary mental mechanism that distorts judgment — you can't fully protect yourself from it because it operates outside awareness. A logical fallacy is a deliberate or unintentional error of reasoning in an argument — an identifiable and nameable logical flaw. These categories overlap: a fallacy can exploit a bias. The two corresponding decks complement each other.
No, and psychology research confirms this. Knowing about confirmation bias doesn't prevent you from activating it. What helps: developing reflex habits that slow down information processing before validation — exactly what regular training through flashcards on concrete cases achieves.
Yes. The 'Information Verification Methods' deck covers operational techniques like the SIFT method, lateral reading, reverse image search and primary vs secondary source evaluation. These techniques apply immediately to your daily news reading.
Yes. Rhetorical manipulation and cognitive biases aren't limited to public debate — they're omnipresent in internal presentations, board meetings, negotiations and decision-making under pressure. Managers who master these tools make better decisions and run better meetings.
