What Are Social Sciences?

Social sciences are the academic disciplines that study human behavior, social organization, and the structures and processes by which people live together. They include sociology, psychology, economics, political science, anthropology, communication studies, and related fields. Unlike the natural sciences, which study phenomena that exist independent of human interpretation, social sciences examine objects (institutions, norms, networks, meanings) that are partly constituted by the beliefs and actions of the people who participate in them.

For engineers and technologists, the social sciences provide empirical knowledge about users, organizations, and societies that shapes how technology is designed, deployed, and governed. Human factors engineering, technology policy, and human-computer interaction all draw systematically on social science methods and findings.

Behavioral Science and Psychology

Behavioral science studies how individuals make decisions, form habits, respond to incentives, and interact with designed systems. Psychology contributes theories of perception, memory, attention, motivation, and emotion that are directly applicable to interface design, safety engineering, and health behavior change interventions. Cognitive psychology informs the design of controls, displays, and workflows to match human information-processing capacities and limitations.

Behavioral economics, which blends psychology with economic theory, has demonstrated that human decision-making systematically departs from the rational-agent model: people are loss-averse, influenced by how choices are framed, and susceptible to cognitive biases that compound in high-stress or high-complexity environments. ACM's Digital Library contains extensive HCI research applying behavioral findings to interface design and persuasive technology.

Sociology and Social Network Theory

Sociology studies the structures and dynamics of human groups, organizations, and institutions. It examines how social norms emerge and change, how organizations coordinate, how inequalities are produced and reproduced, and how social change occurs. For technology studies, sociology provides tools to analyze why some technologies are adopted and others are not, how technical standards are negotiated, and how digital platforms affect social inequality.

Social network theory analyzes relationships among actors as graphs whose structure influences information flow, influence, and coordination. The concepts of network centrality, clustering, and bridge positions apply to email communication within organizations, citation networks in science, and friendship networks on digital platforms alike. Research on network effects and platform dynamics appears regularly in IEEE Transactions on Network Science and Engineering.

Journalism and Communication Studies

Journalism and communication studies examine how information is produced, distributed, and received in societies. The field addresses professional norms of reporting, the economics of news production, the social effects of media framing, and the structural conditions that enable or constrain freedom of the press. Digital technologies have transformed journalism by disrupting advertising-based business models, enabling direct-to-audience publishing, and accelerating both information and misinformation distribution.

Computational journalism applies data analysis, natural language processing, and algorithmic systems to news research and production. Automated fact-checking, structured event extraction, and audience analytics tools raise questions about accuracy, accountability, and the professional role of journalists. NiemanLab at Harvard documents evolving practices at the intersection of technology and journalism.

Applications

Social sciences contribute to engineering and technology practice in a range of ways:

• Human factors: ergonomics, cognitive psychology, and sociology of organizations inform the design of workplaces, controls, and safety systems to reduce human error.
• User experience: behavioral science and ethnographic research guide the design of products and interfaces that fit users' mental models and workflows.
• Technology policy: political science and institutional economics inform regulatory design for telecommunications, data protection, and platform governance.
• Health communication: social psychology and communication studies guide the design of public health campaigns, patient education materials, and clinical decision support systems.
• Organizational design: sociology and organizational psychology help technology companies and institutions manage change, coordinate distributed teams, and assess cultural barriers to adoption.
• Misinformation research: communication studies and network theory identify how false information spreads and what interventions reduce its reach.
