I've heard that was myth or perhaps "cerebral" was code for something else. Maybe
@Harvey or
@Maurice can enlighten me. (us?)
Yeah I fail to see how "The Cage" was any more or less cerebral then "Where No Man Has Gone Before".
Both deal with the psychological aspects of the human condition, and the dreams in fantasies that humanity keeps hidden and don't dare expose.
The only big difference I see is that the 'action piece' that had Pike involved in a knockdown drag out fight to the death was pretty much in the middle of "The Cage", and the last act of the episode was Pike and company philosophizing with the keeper, and the reveal of why Vina would decide to stay.
In "Where No Man Has Gone Before"; The last act is primarily of Kirk and Mitchell having a knock-down drag-out fight, with Kirk being saved by Dr. Dhaner, depowering Mitchell enough so that Kirk can ultimately find a way to overcome him.
Yes there's some philosophizing; but it's quick, and comes right after the big action sequence.

I think that's the real difference between the two pilots, and that change in structure is what ultimately sold the suits on the series.
Also, remember it was GR who claimed they all stated it was "too cerebral'. There were other things that NBC was concerned about, including the fact that he cast his mistress in a lead role; and given the projected cost of this series what would happen if it became a hit but during production GR and Major Barrett broke up?
The pilot was very expensive and took a long time to produce, and I remember one of the things NBC thought was that it would not be possible to maintain this level of production and turn out one new episode a week for broadcast.
That was part of the goal of the second pilot, to prove that they could do an episode a week and deliver something to the network to broadcast.
The second pilot did deliver on that because it had a much lower budget, and was shot a lot faster and turned around a lot quicker than the first pilot; so the suits were also satisfied that The show could be produced for a reasonable cost, and episodes could be delivered on time to the network for broadcast.
