The History of the Written Questionnaire
Launch library · evergreen read
The written questionnaire offered something the spoken interview could not: a standardised set of questions, asked identically to every respondent, making comparison between many answers considerably more reliable than informal conversation ever could.
This standardisation came at a cost, since a fixed written question cannot adapt in the moment the way a live interviewer can, missing the follow up opportunities that a genuine spoken exchange would naturally allow.
Researchers gradually learned to combine both approaches, using structured written questionnaires for breadth and occasional spoken interviews for depth, treating the two formats as complementary rather than as competing alternatives to each other.
The written questionnaire's basic promise, comparable answers gathered at scale, remains as valuable today as it was at its origin, even as the specific tools used to distribute and analyse it have changed considerably. Together, the two approaches continue to shape how organisations gather opinion at any meaningful scale.
