The Flash Application My Evidence by Exploratorium, Museum of science art and human perception, explores and then visualizes the way we get to know what we know. The user is asked to answer questions about facts that are hard for the individual to experience by himself. For example
“Humans cause global warming”is a theory believed by many people but quite hard to proof by one individual. Going further it’s nearly impossible for the individual to know such things if it’s on its own. The answers to these questions range from
“I noticed or experienced”to
“I heard on TV or radio”. Further attributes of an answer are the place where someone learned it, the person’s gender or age and how much the author refutes or supports the stated fact.
