key concepts in thinking, reading, and reflection.
Active reading is a method of engaging with text through questioning, annotating, and reflecting — rather than passively scanning words on a page.
Compound thinking is the process by which small, regular reflections accumulate over time into a rich web of interconnected ideas — each new reflection building on and connecting to previous ones.
Critical thinking is the disciplined process of evaluating information, arguments, and assumptions to form a reasoned judgment — rather than accepting claims at face value.
Deep reading is sustained, focused engagement with a text that involves critical analysis, emotional connection, and reflection — as opposed to skimming or scanning.
An information diet is the deliberate curation and limitation of your information intake — choosing quality over quantity to improve thinking, focus, and retention.
Metacognition is thinking about your own thinking — the awareness and regulation of your cognitive processes, including how you learn, remember, and form opinions.
Reflective thinking is the deliberate process of examining your own thoughts, beliefs, and responses to experiences or information — turning raw input into personal insight.
Slow thinking is deliberate, effortful cognitive processing — what psychologist Daniel Kahneman calls 'System 2' thinking — as opposed to the fast, automatic, intuitive judgments of System 1.
Spaced repetition is a learning technique where information is reviewed at progressively longer intervals to maximize long-term retention.
The forgetting curve is a model showing how information is lost over time when there is no attempt to retain it — typically losing 70% within 24 hours.
