No matter how well you compose a piece of writing, no amount of creative technique will save your work if your details aren't correct. That's why checking facts is just as important to writing as using a grammar checker - your work's credibility rests on it.
When writing for information content, you need to use facts that you have researched in order to support your ideas or arguments. Without these given details, you won't be able to think for a better concept of your topic which requires influencing the public.
Although there are times where real facts are not necessary in writing such as story telling or any fiction contents, where the writer needs to create a his story's own world, however, when writing for a non-fiction content, you really must stick to the facts. But then, these facts must not be created by a single person where you just accidentally heard or where these facts are just basically a person's own opinion. Facts needed to be verified. It must be real and worth believing.
In order to write such a reliable and truthful article, dig up for more information that will help you support your writing. How could your reader's believe in what you have written if all of your contents were just mere lies or an invented story?
Basically, when you do some research over the internet, there are pages where they are telling the truth and there are those who wanted to cause an issue and display a false news or information about the topic that they are discussing.
What you need to is don't stick to a single source of information. Dig up for more and read on those contents that are reliable and officially holding on with real details. This is how you are going to verify information.
It's your job to check the veracity of your information. While some editors will do some fact-checking on their own, most won't consider it part of their job. If the details you include are false, the burden is on your shoulders.
Hiring A Fact-Checker
Some people employ a fact-checker to verify their work. While fact-checkers can't be expected to know everything there is about a subject, they should be, at bare minimum, conversant in it. If they have that going for them, there's a good chance they will know where to properly verify all the information in your text too.
There are fact-checkers of different kinds, each one with their own areas of expertise. If you wrote a piece about new forms of treatment for a specific disease, a medical doctor, regardless of specialization, may be able to check it adequately, as they would know whether the details make sense and where they can look to verify your information.
You need to be resourceful when verifying your facts. The more important your piece is, the greater the requirement to guarantee the information you include. Can you imagine getting a three-page piece on a national magazine only to have readers correct your details, chastising you for not doing your job? That stings. Bad.
