How Randomized Controlled Trials Reveal True Causality

Randomized Controlled Trials (RCTs) are considered the gold standard for establishing causal relationships because randomization balances known and unknown confounders, control groups provide clear comparisons, and reproducibility ensures reliable results, though practical limitations like cost and ethics often require alternative observational methods.
