True Or False: FALSE

This fallacy stems back to 19th-Century scientist Hermann Von Helmholtz, who drew two identically-sized squares with horizontal and vertical stripes on them. However, on the human body, the opposite is actually true. Peter Thompson of the University of York did an experiment where people compared 200 pictures of women in horizontally and vertically-striped dresses, and asked them to pick which of the two were thinner. To actually make the women appear to be the same size, the women in horizontal stripes had to be six percent wider than the woman in vertical stripes. How's that for an optical illusion?
