RealDrives measures not only preferences, but also perception of the environment and behavior adapted to it in 6 different drives (colors). Completing the RealDrives survey takes only 15 minutes!
Before anything else, it is important to understand that behavior is a means to accomplish things. The drive wants something, the environment is valued, and then behavior is deployed to achieve what someone wants.
So behavior and preference can differ a lot; People often act differently than you would expect based on their preference - this is because of the impact of their environment. RealDrives measures how this works for someone.
