Whether or not they understand Bayes, some groups of people are more concerned about what their posteriors will become proportional to whether they choose pizza and&#x2F;or froyo.<p>In those cases, despite your information being generally probabilistically correct for your goal, the worst decision could be giving them something that they&#x27;ll eat (and enjoy) or want to eat but can&#x27;t. You&#x27;re predicting for what to bring on a first encounter, and the best answer could be to bring nothing until you have better information.
