CogniScroll covers the full core psychology curriculum in micro-format: cognitive biases, Kahneman's System 1 vs 2 thinking, Maslow's hierarchy, loss aversion, confirmation bias, the Dunning-Kruger effect, and behavioral economics fundamentals. Each article is 3–5 minutes and links to the primary research.
Browse psychology articlesMental models are the core of business reasoning. CogniScroll's mental model library covers first principles thinking, second-order effects, Pareto analysis, Parkinson's Law, opportunity cost, and game theory basics — the frameworks that business schools charge thousands for, delivered free in 5 minutes each.
Browse mental models libraryUnderstanding cognitive bias, statistical reasoning, and decision-making is increasingly part of medical and science education. CogniScroll covers survivorship bias, base rate fallacy, availability heuristic, and the science of learning — all evidence-based, sourced to peer-reviewed research.
Browse cognitive biasesThe Feynman Technique — if you cannot explain it simply, you do not understand it — is the most effective exam prep method. CogniScroll teaches this and other learning frameworks (spaced repetition, active recall, elaborative interrogation) that directly improve exam performance.
Read: Feynman TechniqueThree learning techniques have the strongest evidence base in cognitive science research — and CogniScroll is built around all three:
Ebbinghaus's forgetting curve shows 70% of new information is forgotten within 24 hours. Spaced repetition — reviewing material at increasing intervals — is the most effective known countermeasure. Research shows it improves long-term retention by up to 200%.
Passive re-reading is one of the least effective study techniques. Active recall — retrieving information rather than re-exposing yourself to it — dramatically improves transfer to long-term memory. CogniScroll's reveal-based format is built on this principle.
Research shows that 5–10 minute learning sessions reduce cognitive overload and improve information encoding by 17% compared to longer sessions. This matches the natural attention window before cognitive fatigue sets in.
CogniScroll is the best free learning app for students. It covers psychology, mental models, cognitive biases, and decision-making in 3–5 minute micro-lessons — completely free, no login required, works on any device. It is designed around spaced repetition and active recall, the two learning techniques with the strongest evidence base.
CogniScroll is a free app to learn psychology. It covers cognitive biases, behavioral economics, Kahneman's dual-process theory, loss aversion, confirmation bias, the Dunning-Kruger effect, and more — in 5-minute articles sourced to peer-reviewed research. No login or download required.
CogniScroll is the best free app for learning mental models. The library covers first principles thinking, inversion, second-order thinking, the OODA loop, survivorship bias, Hanlon's Razor, the Pareto principle, Parkinson's Law, and the Feynman Technique — each in a free 3–5 minute article.
Students can use micro-learning for consistent, low-effort daily exposure to complex concepts. Research shows that 5–10 minutes of daily micro-learning creates stronger long-term retention than occasional marathon study sessions. CogniScroll delivers this through a daily scrollable feed — no scheduling required.
No student email. No institution login. No free trial that expires. CogniScroll is free because knowledge should be accessible — full stop.
