Mindreading with fMRI

A statistician reports:

Brain scans may be able to predict what you will do better than you can yourself . . . They found a way to interpret "real time" brain images to show whether people who viewed messages about using sunscreen would actually use sunscreen during the following week.

The scans were more accurate than the volunteers were, Emily Falk and colleagues at the University of California Los Angeles reported in the Journal of Neuroscience. ...

But these results are not as impressive as they sound, as Gelman explains. If they ever figure out how to do fMRI mindreading, it will be a bigger story than this.
