If you are presenting yourself as a subject matter expert or authority, it's imperative that you have your facts straight before delivering them to a waiting audience.
In the age of fact-checking, it's especially important to make sure that you have done your homework and fully researched your topic and supporting evidence because chances are, your audience already has.
You will only enhance your credibility and authority by making sure your information and sources are solid and accurate.
How do you know if your sources are "good?" You'll want to make sure your sources are reliable, unbiased, and current. To do this, seek out information from trustworthy sources. Typically, you'll turn to scholarly sources such as academic journals, scientific research, or data. You should also understand that scholarly research comes in primary and secondary sources.
A primary source is an original document containing content and data created or collected by the author. Primary sources can include interviews you conduct to gain information and data, collections of letters, lab reports, autobiographical, and literary works. Secondary sources are written about primary sources and include documents such as reviews, critiques, biographies, and other scholarly books or journal articles.
To find academic and scholarly sources, asking your local librarian is one of the best ways to validate whether or not a source you have found is reliable, unbiased, and current.
You can also access databases of scholarly sources online, including:
Always cite your sources whenever or however you can. You never want to be accused of pulling information or data from an unreliable source, or worse yet, just making it up.
You also don't want to be accused of directly lifting, stealing, or even borrowing someone else's words. Never take someone else's words and claim them as your own.
