It is possible that your results may change a little bit. But, the Discovery Survey is designed to capture your natural, ingrained tendencies. Those tendencies tend to be stable over time. For example, each person tends to have a general tendency to be talkative or quiet (or somewhere in the middle), and this tendency tends to stay consistent across one’s life.
That said, if you deliberately select completely different answers and don't answer honestly, your results will change and may change drastically. Our research demonstrates that authentic, honest responses will provide you with the most valuable information to support you in your career path.
