That's 2/3rd of medical research paper where the standards are the highest. I'd be shocked if the rate was only a mere 66% everywhere else. You'd have to be a fool to take on faith anything published today that wasn't replicated, hopefully more than once.
According to [1], replication rates in psychology varied from 23% to 38%. Social psychology was around 25%, while the more rigourous cognitive psychology was around 50%.
