In intellectual history, the Idea of Progress is the idea that advances in technology, science, and social organization can produce an improvement in the human condition. That is, people can become better in terms of quality of life (social progress) through economic development (modernization), and the application of science and technology (scientific progress). The assumption is that the process will happen once people apply their reason and skills, for it is not divinely foreordained. The role of the expert is to identify hindrances that slow or neutralize progress.
