The difference between a study and a survey
Launch library · evergreen read
A survey asks people directly about their views, experiences or behaviour, and its value depends heavily on who was asked and how the questions were worded at the time. A study more broadly refers to a piece of research, which might use a survey, but might instead observe behaviour or test an intervention directly.
Surveys are useful for capturing opinion and self reported experience, but they rely on people accurately recalling and honestly reporting their own behaviour, which is not always reliable, particularly on sensitive topics where people may answer in a way that feels more socially acceptable than the truth.
Understanding which method underlies a claim helps set the right expectations. A survey result tells you about stated opinion at a moment in time, while a study designed to observe actual behaviour may tell a different, sometimes more revealing, story about the same underlying issue entirely, one that a stated opinion alone would never have surfaced.
