At the close of the experiment in each village, were subjects who were under the impression that the deadline to deposit the affected notes had already passed told that in fact it had not? Also, was there a concern that subjects who had such a mistaken impression (possibly as a result of experimenters' information dissemination) would rid themselves of notes that could have been deposited?
