My Morals

There's an interesting website, YourMorals.Org, where they're trying to understand people's morality.  It's run by a bunch of academics studying psychology.  They offer numerous questionnaires dealing with various issues.  This month's offerings include questions about:

--What do you find disgusting and how does it relate to morality?

--What type of city would you like to live in?

--What is your attitude on crime and punishment?

--Compare your values on 10 dimensions from hedonism to benevolence.

--What is your "style"' of relating in romantic/love relationships, and how does that relate to morality?

Unfortunately, in their desire for rigor, they demand you register before you answer any questions.  Even though they promise privacy, I generally prefer not to register at websites.  So it occurred to me, are their results going to be skewed because their samples will be missing paranoid people like me?
