T. Chartrand et al., When manipulation backfires: The effects of time delay and requester on the foot-in-the-door technique, J APPL SO P, 29(1), 1999, pp. 211-221
We examined the effects of 2 variables on compliance rates within the foot-
in-the-door procedure. Participants who agreed to a small request were pres
ented with a larger request either immediately after the first request or 2
days later. The second request was presented either by the same person or
by a different requester. Compared to a control group receiving only the la
rge request, participants were more likely to agree to the second request i
n all experimental conditions except one. When the same requester presented
the second request without delay, participants were less likely than the c
ontrol group to agree to the target request. This latter condition represen
ts a situation in which typical foot-in-the-door procedures can backfire on
the requester.
