Question: Your friend reads about a study in an epidemiology journal
Your friend reads about a study in an epidemiology journal that estimates that the chance is 15 out of 1 million that a teacher who works for 30 years in a school with typical asbestos levels gets cancer from asbestos. However, she also knows about a teacher who died recently who may have had asbestos exposure. In deciding whether to leave teaching, should she give more weight to the study or to the story she heard about the teacher who died? Why?
