Funny, but could be useful. I see this very similar to deletion checks on web pages that we put for users, to avoid an unwanted situation. By simplifying the scenario as a binomial distribution ( right and wrong decision). It would be interesting to calculate the change/reduction in probability of the wrong decision by using these tools/checks and the utility of wrong decision, which in case of the phone app could be anywhere from awkward silence to extreme embarrassment. In case of deletion of data, it could be anywhere from a simple slap on wrist by supervisor to job loss.
