Experiments estimate causal effects by comparing outcomes across groups. When assignment is random, each group is expected to be similar before treatment.
Random assignment reduces selection bias and makes the observed difference easier to interpret as a causal effect.
Every source becomes a book with traceable citations, active recall, notes, and review history.
Ask questions against the current paragraph, chapter, or full book. Answers keep citations attached.
Highlights, notes, concepts, tags, and semantic search accumulate across every book.
