The root of the replication crisis in social sciences is not just that many papers fail to replicate, but that there is no way to clearly resolve a result that fails to replicate. A paper claims that pre-K increases test scores a decade later, another paper claims it doesn't, and there's no clear resolution. The disagreement just festers, with both sides citing research that supports their opinion. The argument often "spills out" into the public sphere. In mathematics and computer science, there are many errors in published papers. However, once you point out an error, it's usually pretty straightforward to resolve whether it's really an error or not. Often there is a small error which can be fixed in a small way. Exceptions like the abc conjecture are rare.
