Critical theory of technology draws from both critical theory and science and technology studies to understand the relationship between technology and society. It agrees with social constructivism in STS that technology is shaped by social factors rather than being neutral or deterministic. However, it also draws from critical theory's concern with how rationalized systems can limit human agency. The approach aims to open up democratic debate about technology while preserving STS empirical case study methods. It incorporates key STS concepts like interpretive flexibility but questions symmetries between social groups or humans and non-humans.
