Previously, I’ve noted that it’s important to “remember the iceberg” and present only the most relevant 10% of what you know about your topic to your audience. As it turns out, this is not only practical (you only have time to present 10%)—it can actually be even better for your audience (and your cause).
In Captivology: The Science of Capturing People’s Attention, Benn Parr cites a 2008 study in which “researchers at Yale University and the University of Innsbruck found that stock traders with more financial and market information did not perform better than their counterparts. Instead, the quality of information mattered more. In their research, they learned that well-informed traders—specifically insiders—clearly had the best financial performance, not because they had the most amount of information but because they had the best information.”
While it’s tempting to think that if you give your audience more information, they’ll automatically make better decisions, this isn’t necessarily the case. Not being experts on your topic, the audience needs your help to know what’s important. Seen through this lens, your job as a speaker is not to share everything you’ve learned about your topic, but rather to pre-digest your topic for your audience, sharing only the information that’s really important to them, the information that will help them make better decisions (and in doing so, hopefully support your cause).
