In a function magnetic resonance imaging (fMRI) study, action decisions were correlated with (multivariate patterns in) fMRI data. Action decisions were made in various meaningful contexts. We found that classification of intentions is possible when context remains stable. However, classification drops to chance-level when different contexts are used. This suggests that the brain processes driving action decisions are a dynamic configuration of sensorimotor processes. This is at odd with the notion of ‘intention,’ which suggests an invariant representational core. This data is in line with recent theoretical advances that suggest that the notion of intention refers to a post-hoc explanation of an action, rather than a brain state.
