But when the text was accompanied by a simple graph making exactly the same claim, 97% believed it, say Aner Tal and Brian Wansink of Cornell. Graphs’ persuasiveness has nothing to do with ease of understanding; instead, a graph signals to readers that the information has a scientific basis, making it more believable, the researchers say.
