Some evidence for (2) is that before the 1957 act no civil rights legislation had been passed for 82 years[1], and after it three more civil rights acts were passed in the next 11 years, including the Civil Rights Act of 1964, which in my understanding is considered very significant.
there’s an exogenous factor, which is that the entire country was shifting leftward during the 50s and 60s. it’s plausible that the 1964 bill would have passed anyways without the 1957 bill, possibly even earlier

Going off what’s listed in the wikipedia article on civil rights acts in the United States.

Fair enough yeah. But at least (1)-style effects weren’t strong enough to prevent any significant legislation in the near future.
