This essay provides evidence to support a promising conceptual and potentially practical set of ideas at once both principled and effective found in the work of Max Weber and Alfred Schutz addressed to the issue of ‘adequacy’ as a goal in social research. Efforts to achieve adequacy beyond the epistemological conditions required by Weber’s demand that evidence meet both causal adequacy and adequacy on the level of meaning were significantly refocused by Schutz’s later concern, responding specifically to Weber, that the (...) social sciences also address themselves to his postulate of adequacy. It states that “Each term used in a scientific system referring to human action must be so constructed that a human act performed within the life-world by an individual actor in the way indicated by the typical construction would be reasonable and understandable for the actor himself, as well as for his fellow men”. A serious attempt to implement a more expansive notion of adequacy by practically activating this postulate in the ways suggested can be beneficial not only for the social research situation but in everyday life as well.

This introduction to the following five articles discusses concepts, practices and debates before and after the adoption of the term “questionnaire” in the late nineteenth century. Information gathering by way of itemized questions was established in the early modern period (c. 1500–1700). Developments associated with questionnaires in the modern period (such as mass standardized items) began in the late 1800s; but there was significant scrutiny of the questionnaire itself in the decades between the two World Wars.
