advertising agency<\/a> presented a graph that showed a steadily rising line. The y-axis showed time in years, but the x-axis had no label. Presumably, it was profit, but without numbers, it was impossible to know if profits were jumping by millions or cents.<\/li><\/ul>\n\n\n\n4. In bar graphs, use illustrations instead of bars.<\/strong> In a bar chart, the height of the bar is what indicates the measurement. When you replace a bar with an illustration\u2014say, a bag of money\u2014when you increase the height of the moneybag, all the other dimensions scale proportionally. Increasing the width and depth (if 3-D) of the image makes the differences between the two images look much larger.<\/p>\n\n\n\n- (Shortform example: In the illustration below, the skulls represent the death rate from a certain illness. Before a liar\u2019s medication was adopted, the death rate was 60 out of 1 million, represented by a skull at height 60. After adoption, the death rate halved to 30, represented by a skull at height 30. However, visually, the rate appears to have dropped by far more than half because the image appears to have decreased by more than half: The whole image was scaled down proportionally, rather than just the height being halved.
Death rate pre-adoption:\ud83d\udc80<\/strong>Death rate post-adoption:\ud83d\udc80<\/li><\/ul>\n\n\n\nThis trick can also give a false impression, depending on the illustration, that whatever\u2019s represented in the image is now larger than it used to be.<\/p>\n\n\n\n
- For example, if a graph compares the size of the cow population <\/em>between two years, but uses two images of cows, one smaller and one bigger, people might think the size of cows <\/em>has increased instead.<\/li><\/ul>\n\n\n\n
5. In before-and-after photos, change <\/strong>multiple <\/em><\/strong>things about the subject<\/strong> after the before picture has been taken to make the change look more significant than it really is.<\/p>\n\n\n\n- For example, a photo of a woman before she started using a hair rinse might be taken with poor lighting and printed in black and white. In the after photo, she might be well-lit and smiling, and the photo might be printed large in full color. The after photo looks better not because the hair rinse made her hair look better, but because the photography was better.<\/li><\/ul>\n\n\n\n
6. In maps, use the many variables to create visual illusions.<\/strong> Since maps include many features (legends, border, different-sized regions, and so on), they\u2019re excellent tools for misdirection.<\/p>\n\n\n\nFor example, the First National Bank of Boston produced a map called \u201cThe Darkening Shadow\u201d that showed how much of the national income is spent by the federal government. The spending was represented by shading in enough states that federal spending was equal to the total income of those states. <\/p>\n\n\n\n
Of course, states have different areas and populations. The bank chose to shade the states with small populations (and therefore low total incomes) and large areas.<\/strong> As a result, their map shows over half of the western United States shaded, which makes federal spending look huge.<\/strong><\/p>\n\n\n\nIt would have been just as accurate to shade the small, highly populated states such as the ones on the eastern seaboard. Choosing this method, only a small portion of the map would be shaded, and the spending looks small\u2014but this wouldn\u2019t have suited First National\u2019s agenda, so they didn\u2019t do it.<\/p>\n","protected":false},"excerpt":{"rendered":"
How can people manipulate graphs to change how you perceive them? What are the six most common forms of image manipulation? It is possible for someone with an agenda to manipulate an image (whether that be a graph, a map, or a photo) to control the message you take away from them.
