A thorough distinction between explanatory and descriptive concepts reveals a radical explanatory and a trivial descriptive doctrine in current neuroscientific research. The explanatory approach examines the neuronal substrates of the mind, whereas the descriptive one deals only with its correlates.

We welcome a computational theory on social groups, yet we argue it would benefit from a broader scope. A neuroscientific perspective offers the possibility to disentangle which computations employed in a group context are genuinely social in nature. Concurrently, we emphasize that a unifying theory of social groups needs to additionally consider higher-level processes like motivations and emotions.
