fMRI is just a way of measuring brain activity. And no it doesn't explain everyone's every behavior, not even close. That's not how science even works. Studies are
very specific, if this stimulus is presented under these conditions then group A will react in one way while group B will react in a slightly different but discernable way.
It's all very domain specific and extremely slow to produce these gestalt theories that you seem to think are the whole of psychology.
