Sociologists explore the notion of thinking infrastructures to refer to a broad range of phenomena such as rankings, ratings, and algorithms that structure attention, shape decision making, and guide cognition. In sections on valuing, tracing, governing markets, and infrastructure society, they consider such topics as prospective sensemaking and thinking infrastructure in a large-scale humanitarian crisis, performing apparatus: infrastructures of valuation in hospitality, smart grids and smart markets: the promises and politics of intelligent infrastructures, a communication perspective on the fabric of thinking infrastructure: the case of social media analytics, and designing infrastructure for the poor: transactions within unstable ecologies.
