概要	Holsti's method is a percent-agreement reliability index for content analysis, popularized by Ole Holsti's 1969 textbook and derived from Osgood's earlier formula. For two coders it is twice the number of coding decisions on which they agree divided by the total number of decisions each made — a simple, intuitive measure of how often coders reach the same judgment.	Intercoder reliability is the degree to which independent coders, applying the same coding scheme to the same content, arrive at the same coding decisions. In content analysis it is the central guarantee that findings reflect the messages rather than the idiosyncrasies of who happened to code them, and reporting a chance-corrected reliability coefficient is a near-universal requirement for publication in communication research.
