People of different opinions process political data differently

That those who lean to opposite ends of the political spectrum think differently from each other is obvious. That such differences show up in brain scans is intriguing. Brain scanning is a low-resolution approach to studying neural activity, incapable of seeing how the cells which do the actual thinking are connected to each other. Yet, using this fairly crude technique, two groups of researchers now claim to be able to distinguish the neural responses of left- and right-wingers.
