 As discussed, decoding methods allow one to associate observed brain activity with previously observed brain/behavior correlations. In addition, such methods can also be used to predict future behaviors, insofar as these are correlated with observations of brain activity patterns. Some studies have already reported predictive power over upcoming decisions (Soon et al., 2008). Increasingly, we will see neuroscience or neuroimaging data that will give us some predictive power over longer-range future behaviors. For example, brain imaging may allow us to predict the onset of psychiatric symptoms such as psychotic or depressive episodes. In cases in which this behavior is indicative of mental dysfunction it raises questions about stigma, but also may allow more effective interventions.
