You got downvoted, but I think you are right in a way. Direct neurophysiological recording is not a panacea because either 1) you can't implant electrodes in your participants ethically, 2) Recordings usually are limited in number or brain areas. That said, I think the key is "convergent evidence" that spans multiple levels and tools of analysis. That is how most progress has been made in various areas, like autism research (my current work) or memory function (dissertation). We try to bridge evidence spanning human behavior, EEG, fMRI, structural MRI, post-mortem, electrode, eye-tracking, with primate and rodent models, along with neuron cultures in a dish type of research. We integrate it and cross-pollinate.
