How do you calculate the age of your dog in human years? You probably just multiply it by 7, but that’s wrong. This myth comes from the 13th century, but we still believe in it today. Based on this example, scientists have proven that people are more likely to believe fake facts that seem real and fit the picture of the world they are used to, rather than new facts. Even if the new facts are 100% true, but seem to not be true.
We at Bright Side have read hundreds of studies proving that these 22 not-so-pleasant facts about humans and the world around them are true. But we still have a hard time believing that koalas eat excrement.
