Finding Policy Sources: Think Tanks

Think tanks are public policy research analysis and engagement organizations that generate policy orientated research, analysis, and advice and international issues, thereby enabling policy makers and the public to make informed decisions about public policy.

Think tanks often provide valuable and impartial policy research and information; however, think tanks can be susceptible to biases and outside influences which raise questions about their independence and integrity.  While not affiliated explicitly with a political party, think tanks may have a particular orientation or political leaning around policy issues.
