Conspiracy test

A new BBC TV series explores some of the biggest and most troubling conspiracy theories of modern times.

Do you trust everything you are told or do you think there is usually truth in conspiracies?

Psychologist Dr Patrick Leman, of the Royal Holloway University of London, has devised a test to see how conspiratorial you are.

Once you have answered all 15 questions press submit and we will calculate your score. You will then be able to read Dr Leman's analysis.

1. Strongly disagree
2. Disagree
3. Don't Know
4. Agree
5. Strongly agree

1) There was no organised conspiracy involved in the assassination of John F Kennedy

2) For the most part, government serves the interests of a few organised groups, such as business, and isn't very concerned about the needs of people like myself.

3) I can normally do what I want to do in the world today.

4) Princess Diana's death was an accident.

5) It is difficult for people like myself to have much influence in public affairs.

6) We seem to live in a pretty rational and well-ordered world.

7) My closest friends are very unpredictable. I never know how they are going to act from one day to the next.

8) When I am with my closest friends, I feel secure in facing unknown new situations.

9) Most politicians are sympathetic people and do a good job.

10) I feel very uncomfortable when my closest friends have to make decisions which will affect me personally.

11) The attack on the Twin Towers was not a terrorist action but a conspiracy involving certain Western governments.

12) The American Moon landings were faked.

13) I am certain that my closest friends would not lie to me, even if the opportunity arose and there was no chance that they would get caught.

14) I can rely on my closest friends to keep the promises they make to me.

15) Governments are suppressing evidence of the existence of aliens.

• 51-75:

  Your responses suggest you have a high level of belief in conspiracy theories. You might have reason not to trust others, even people close to you. You may also feel that you are an outsider in terms of society and the political and business decisions that large organisations make.

• 26-50:

  Your responses indicate that you have a medium level of belief in conspiracy theories. You may well be quite trusting of your close friends, partners, those you work with and others but sometimes cannot be sure of all of them all of the time. You may also feel that your voice in terms of wider political decisions is rarely heard or acted upon, perhaps because government and big business is more concerned with their own interests than with those of the average person.

• 15 - 25:

  Your responses suggest you have a low level of belief in conspiracy theories. You may well tend to be trusting of your close friends, partners, those you work with and others. You may also feel that you contribute to political decisions and have a voice that is heard in wider society, albeit a small one.
