Conspiracy Test

Researchers Brotherton, French, and Pickering developed the Conspiracist Beliefs Scale in order to measure belief in conspiracies among the general population. Belief in conspiracies is not well understood, though results indicate that there are stable differences in people’s tendency to engage with conspiracist beliefs. Their test has been validated across four scientific studies and published in the scientific journal Frontiers in Psychology.

What is your degree of belief in conspiracies? For each of the following items, indicate your level of agreement below.

Question 1 of 15
