The first factor is the acquaintanceship with the invitation initiator, the second — the professional solidarity of sociology students (when they are invited by a sociologist). We used a sample of 253 second-year students from two faculties of the Higher School of Economics. The overall response rate was 49%. ANOVA showed a significant effect for the acquaintanceship with the invitation initiator factor: if the request was from a familiar lecturer the response rate is 58%, whereas if the request came from an unknown person, the rate is 44%. At the same time the effect of the professional solidarity factor was not observed.
