Politicians rarely take a step without them.
Corporations do them monthly.

Surveys and polls. They drive decision making across all sorts of organizations, corporations, governments and even palaces. Polls inform a range of strategies, whether related to how countries build support for reform, to how organizations move the needle on behavior change (think smoking, HIV, and drunk driving), to how companies choose the colors of a box of cereal and decide on the jingo that is intended to sell that cereal (crafted specifically to never leave your memory)!
