The goal of the current study was to explore the possible effect of a short mindfulness meditation on decreasing a tendency for miserly processing and degree of myside bias. The author ś sample consisted of 76 students that were assigned into three groups: one with short mindfulness intervention and two control groups (one was given a lecture on cognitive biases and second group was given mind-wandering instruction). The groups did not significantly differ in any of the measured variables (with one minor exception). The results indicate that short-term mindfulness induction was unsuccessful in changing the proclivity for cognitive biases, contrary to what the author predicted.
