Information Literacy: 1. Who's Behind the information

NOAA provides Arctic information and a set of reputable indicators that describe the present state of the Arctic ecosystem and climate.

the phenomenon known as "sensitive dependence on initial conditions." This is sometimes referred to as the butterfly effect, e.g. a butterfly flapping its wings in South America can affect the weather in Central Park. The question then arises — why does a set of completely deterministic equations exhibit this behavior? After all, scientists are often taught that small initial perturbations lead to small changes in behavior. This was clearly not the case in Lorenz's model of the weather. The answer lies in the nature of the equations; they were nonlinear equations. While they are difficult to solve, nonlinear systems are central to chaos theory and often exhibit fantastically complex and chaotic behavior.

Since information is always influenced by its author, analyzing who's behind the information should be a priority when evaluating online content. But too often, students attempt to evaluate information based on elements other than the source, such as the contents of a website, its appearance, or the evidence it supplies. In this lesson, students learn why the source of information is so important and practice analyzing information based on who's behind it.

A front group is an organization that purports to represent one agenda while in reality it serves some other party or interest whose sponsorship is hidden or rarely mentioned. The front group is perhaps the most easily recognized use of the third party technique.

A think tank (also called a policy institute) is an organization, institute, corporation, or group that conducts research and engages in advocacy in public policy. Many think tanks are non-profit organizations, which some countries such as the United States and Canada provide with tax exempt status. While many think tanks are funded by governments, interest groups, or businesses, some think tanks also derive income from consulting or research work related to their mandate. In some cases, think tanks are little more than public relations fronts, usually headquartered in state or national seats of government and generating self-serving scholarship that serves the advocacy goals of their industry sponsors.
