The Information Quality Act (IQA) requires federal agencies to use reliable science when making regulations and disseminating information. Specifically, the IQA requires that the information circulated by federal agencies is fair, objective, and meets certain quality guidelines. It also permits citizens to challenge government information believed to be inaccurate or based on faulty, unreliable data. Business, consumer, environmental and conservation groups have all used the IQA to pursue changes in federal policy.
