The Market Research Interview
Launch library · evergreen read

Businesses seeking to understand consumer preference developed their own interviewing tradition, distinct from journalism, focused on gathering structured, comparable data from many subjects rather than a rich, individual account from any single conversation. Businesses needed answers that could be compared reliably across very different customers and settings.
This tradition contributed methodological rigour to interviewing more broadly: careful attention to question wording, systematic sampling, and an awareness of how easily a poorly phrased question can distort the answers gathered across a large number of separate conversations. Sampling decisions in particular could quietly skew results if not handled with genuine methodological care.
Though its aims differ from journalistic or historical interviewing, many of its lessons about precision and consistency in question design have quietly influenced how interviewers in other fields think about the reliability of the material they gather. Many interviewers outside commercial settings still borrow this discipline when precision matters more than colour.
