Tips for parties: The Appliance of Science
Research shows (Tal & Wansink, 2014) that the mere presence of science-related reasoning (e.g., charts, graphs, formulas) enhances the persuasiveness of a message or argument. Even trivial signals can create such an appearance of a scientific basis. In their studies, Tal & Wansink found that including simple elements, such as graphs, or a chemical formula, increased peoples' belief in a medication’s healing powers - whether or not these were truly scientific or supporting an objective argument. This appears to be due simply to the positive association of science, rather than increased comprehensibility, use of visuals, or recall.
So do some research and, if possible, have some scientific data to support your case.
