Distancing expressions are used to indicate that information comes from an outside source rather than being stated definitively. They can be achieved through verbs like "seem" and "appear", the passive voice as in "it is said", and phrases like "apparently" or "according to". Common patterns include "it seems/appears that", "it is said/reported/believed that", and using the passive voice with verbs of saying and reporting. Noun phrases like "there is little/some/no doubt that" can also distance a claim.
