You get this in linguistics as well. If you read material from the early
days of linguistics, there is quite a lot of rubbish in it. There is also
quite a lot of insight that was simply formalized is wrong, so imcorrectly
dismissed by later researchers.

In generative linguistics, this happened with what is called the
A-bar-trace. The theory stated that when you move a topic or wh-pronoun to
the front of a sentence, it leaves behind a "trace" - a footprint in the
structure, if you will. The evidence was weak but the intuition was good.
During the late 70s or early 80s, they began running tests on brain
activity during speech. Brainwave patterns seem to corroborate the
existance of traces in a very dramatic way. Once the "moved" word has been
pronounced, the brain goes into a flurry of activity which only goes away
once the speaker reaches the point where the trace was hypothesized to be.
That is actually very startling, and I really doubt any syntactician
expected evidence of this kind. Similar evidence of the A-trace is lacking,
but syntacticians ignore that fact.

Lots of linguists today love to discuss the Sanskrit grammarian Panini.
Apparently, he was very modern in his thinking for someone who was working
thousands of years ago.

I have read linguists who never have anything reasonable to say. And yet
they are quite famous in the field. They point out interesting and
troublesome facts, but the way they account for them is non-sensical. Or
rather, they are possible according to the technical capabilities of the
theory they work under, but they are counter-intuitive as to why that
should be the proper analysis. For me, Chomsky falls into that category
most the time.
