In his Art of Thinking course, Peikoff made a crack concerning collaborating with Ayn Rand, "which means taking notes."
The testimony of those on Ayn Rand's intellectual wavelength ("unparalleled genius"; "Mrs. Logic") reminds me very much of people's testimony concerning Stanley Kubrick's thought processes. These two people's minds - Rand's and Kubrick's - were like the smoothest-running engines of cognitive integration, making the seemingly toughest tasks all quite habitual and natural and commonsensical, while everyone else could only try to keep up. It takes years of reality-oriented, focused-on-essentials mental processing to automatize one's cognitive activities at such a true-genius level.
That is all.
