If I told you there was a new medicine effective in treating a previously untreatable illness, you might be interested.

But if somewhere in the midst of that evidence there is a nice graphic, demonstrating how effective the medication is, you will be more likely to believe that the medicine works. That was what a team of researchers led by Brian Wansink found. Here is a graphic – and now I know you will believe that the study was excellent – showing the percent of people who believed the advertising claims with and without an accompanying chart:
