## TL;DR
The scientific method — observation→question→hypothesis→experiment→analysis→conclusion — is humanity's most reliable path to knowledge. Its power lies not in proving theories true, but in systematically eliminating false ones.

## Core Explanation
Thomas Kuhn's paradigm shift model (1962) describes scientific progress as revolutionary transitions: normal science operates within paradigms until anomalies trigger crisis, resolved by adopting new paradigms.

## Detailed Analysis
Modern reforms address weaknesses: p-hacking, publication bias, low statistical power. Open Science: preregistration, data/code sharing, preprint servers (arXiv, bioRxiv), Registered Reports (peer review before results known).
