Rand herself didn't understand emergence (she casting a biologist as the embodiment of scientific corruption, because there is too much complexity in his area of study for any one human brain to be familiar with), and also didn't understand much about cybernetics, etc.

That's hardly the start of it. She opposed relativity and QM, and fence-sat on Evolution.

ETA:

I don't think "1957" is mcuh of an excuse either, particularly about evolution. For another thing, she never wavered till her death in the 80s. It makes no sense to focus on Bayes, unless your are a Bayes cultist. Rand was unaware that a realistic, raitonal science-orientated form of philosophy had arisen since she was spoon-fed Hegelianism in the early 20th century, and remained unwillingly to connect with it even after John Hospers painfully explained it to her. That's the acid test of whether you are interested in promoting ideas or yourself.
