When making an argument, writers and speakers will often draw on evidence. Citing evidence—which can take the form of studies, research, statistics, graphs, facts and figures—brings credibility and authenticity to an argument.
The use of evidence may encourage readers to see the writer as informed and considered in their understanding of an issue, creating the perception of reliability. The tone of a piece of writing doesn’t necessarily have to be logical to use evidence, even writers who adopt a highly emotive approach to making their argument may draw on evidence.
