Conservatism test uses statistical methods to make an accurate assessment of how conservative you are compared to everyone else, both globally and regionally. The test score alone is not the determining factor. It’s your position relative to the average that more accurately assesses the extent of your political leanings. Since this is an American conservatism test, the results may not resemble the same ideology in your region. Still, the regional statistics will give you a better estimate than the global statistics, even if you are not from the USA.
This conservatism test is not based on any political party like the Republican Party. Though it’s true that Republican voters will generally have a higher score in this test, than the Independent or the Democrat voters, in most cases at least.
American conservatism differs from conservative ideologies in other parts of the world. For example, in USA conservatives strongly favor small government, deregulation and free market, which is often not the case in other parts of the world. And of course, there are topics that may not even be on the table in other countries, like the second amendment rights. Still it’s fair to say that despite these significant differences, most conservative ideologies in the world have more in common than not.
