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.	Manifest content analysis is a quantitative research technique that systematically counts the explicit, surface-level features of communication messages — words, sources, themes, images, or actors that are directly visible in the text or media artifact — according to a predefined coding scheme. Rooted in Bernard Berelson's classic definition of content analysis as the 'objective, systematic, and quantitative description of the manifest content of communication,' it is one of the foundational empirical methods of mass communication and media research.
