In "State of Fear," Michael Crichton emphasizes that science is fundamentally different from politics in its reliance on consensus. He argues that scientific truth is not determined by majority opinion but by the evidence provided through rigorous investigation. A single scientist can make a significant breakthrough if their findings are replicable and grounded in reality, irrespective of whether they align with the prevailing views of their peers.

Crichton highlights that historical advancements in science often stem from those who challenge existing beliefs. The most notable scientists have made their mark not by conforming to consensus but by presenting verifiable results that differentiate their work. Thus, he posits that reproducibility, not agreement, is the cornerstone of true scientific progress.
