It has been fairly stable. Creationism went from 38% in 1983 to 33% today (but with enough variability that it was also 38% as recently as 2017). "God made evolution happen" is another 40-44%, again fairly stable. Given the margin of errors in the polls, I'd say that they're pretty much the same, or a very slight decrease.

"It's just evolution" did change noticeably, but it's still only 22%. That's up from 9% in 1983.

So presumably the "i dunnos" are decreasing. But nothing seems to alter the misinformation very much.
