One thing I do not like about research such as this is that they only report mean overconfidence values. How can you conclude from the mean that everyone is overconfident? Perhaps only halve of the subjects are very overconfident while the other halve are less overconfident.
Just give us all the data! It should be easy to visualize in a scatter plot, for example.
