IT is often considered as a technical science or engineering. Traditionally testers are techies who focus on analysing requirements and turning them into a series of test cases. Some also analyze product risks and write (master) test plans. Focus is on technical and analytical skills. But testing requires a lot more! Testing is about attitude, skills, communication, behavior, collaboration and (critical and/or systems) thinking. The seven basic principles of the Context-Driven School tell us that people, working together, are the most important part of any project's context. That good software testing is a challenging intellectual process. And that only through judgement and skill, exercised cooperatively throughout the entire project, are we able to do the right things at the right times to effectively test our products. In these principles there is a lot of non technical stuff that has a major influence in my work as a tester. This talk gives insight in why testing is a social science. It also gives some examples of what a tester can take away from social sciences. Anthropology teaches us about how people life, interact, something about culture. Education/didactic helps acquire new or modifying existing knowledge, behaviors, skills, values, or preferences. Sociology learns us empirical investigation and critical analysis and gives insight in human social activity. Psychology is the study of the mind and behavior and helps testers understand individuals and groups.
