With the abundance of streaming content available and the ease with which people can access it on demand, the Netflix Cheater Test is a way to keep viewing partners honest with one another.
Since most of Netflix's content comes out in a single dump (i.e. an entire season gets released at once rather than single episodes week by week,) people watching shows with one another can "cheat" and skip ahead while their partner isn't around. The sneaky habit is difficult to stop, but Netflix has gathered data based on several surveys it authored over the past few weeks.
According to the Netflix Cheater Test data, countries in Eastern Europe tended to have the highest degree of faithfulness, with the Netherlands coming out on top. Latin and South American countries saw the highest rates of cheating, with Brazil being guilty of the most cheating.
