#' How important is it to ask pointed questions?
#'
#' In this experiment, each individual was asked to be a seller of an iPod (a
#' product commonly used to store music on before smart phones...).  They
#' participant received $10 + 5% of the sale price for participating.  The
#' iPod they were selling had frozen twice in the past inexplicably but
#' otherwise worked fine. The prospective buyer starts off and then asks one of
#' three final questions, depending on the seller's treatment group.
#'
#' The three possible questions:
#' - General: What can you tell me about it?
#' - Positive Assumption: It doesn't have any problems, does it?
#' - Negative Assumption: What problems does it have?
#'
#' The outcome variable is whether or not the participant discloses or hides
#' the problem with the iPod.
