Tips on Arguing: Vet Your Facts

Vetting your facts simply means looking into them. It may sound like this should go without saying, but failing to double-check a source is one of the most common ways that misinformation spreads.

Internet databases and search engines have given people access to more information than ever. But not all information is created equal. Public relations departments disguise their self-advertising to look like news stories. Poltical groups shape the presentation of facts to fit their agendas. Groups peddling pseudo-science publish their own journals, and conspiracy theorists sometimes make stories up out of whole-cloth.

Even if you are using a well-respected source, there is always a chance that human error will creep in. If you read New York Times articles that are more than a few days old, you may see corrections posted at the bottom of the page. It’s not because they weren’t careful the first time around – it’s because new information has overturned a previous statement, or new sources have provided further details.

There are several ways to get your facts straight, though none is foolproof. Whenever you can, you should always use a primary source over a secondary one. Primary sources tend to be more accurate and deliver more nuances.

Cross-checking is a simple way to make sure your facts are legitimate. If one source says A is true, find a different source – one that is independent of your first source - and see if it says the same thing. If your second source says that B is true, you’ll have to do more research to figure out which is closer to the truth.

If you’re drawing facts from scholarly journals or books, go through their references. Did the “fact” about Thomas Jefferson’s beliefs come from a document he wrote or from Wikipedia? If it came from Wikipedia, it might be correct – but the chances for error are higher.

Another tool often used by researchers to determine whether a given scholarly article is widely accepted by the academic community is to find out how many times it’s been cited by other papers. The more citations, the more likely it is to be useful information.

Unfortunately, there is no perfect way to vet your facts. Eyewitnesses remember things inaccurately. Typing, writing, and speaking mistakes are common. Personal biases can cloud even the most intelligent person’s assessment of a situation.

Vetting your facts is, however, the best way to minimize your own errors. It doesn’t mean that you’ll get everything right, but it will prevent you from getting a whole lot of things wrong.
