Expert writing Tips
Best practice
Use "happened infrequently" when you want to emphasize that an event or situation does not occur often, but you still want to acknowledge that it does occur at least some of the time. This is more nuanced than simply stating something "never happens."
Common error
Avoid using "happened infrequently" when you mean that something has never occurred. "Infrequently" implies that there have been some occurrences, just not many. Use "never happened" if there have been zero instances.
