In the post that started this whole project, I mentioned that “Public Speaking Woman bolsters her facts with dependable resources.”
When you are imparting information that is not common knowledge, and even more so if it is controversial or counter-intuitive, you need to state your resources so people won’t think you’re making this stuff up.
But even when the information is more commonly known, citing statistics, using quotes from experts and referencing published work, can still give your presentation more weight.
Providing credible references and resources for your information and conclusions lets your audience know that you not only know your stuff … after all, you did your research! … but also that you are not alone in your conclusions. The latter helps bring “mob psychology” into your corner.
Obviously, presentations of a more technical or educational nature pretty much require the use of references and resources. But adding in a little third-party quasi-endorsement through famous quotes and anecdotes can also help more personal or inspirational presentation bring the message home, too.
