We prepared a survey that included realistic scenarios of statistical issues that arise in research. Amos colected the responses of a group of expert participants in a meeting of the Society of Mathematical Psychology, including the authors of two statistical textbooks. As expected, we found that our expert coleagues, like us, greatly exaggerated the likelihood that the original result of an experiment would be successfuly replicated even with a smal sample. They also gave very poor advice to a fictitious graduate student about the number of observations she needed to colect. Even statisticians were not good intuitive statisticians.
