The final straw was noticing a comment referring to "the most recent survey I know of" and realizing it was from May 2009. I think it is well past time for another survey, so here is one now.
I've tried to keep the structure of the last survey intact so it will be easy to compare results and see changes over time, but there were a few problems with the last survey that required changes, and a few questions from the last survey that just didn't apply as much anymore (how many people have strong feelings on Three Worlds Collide these days?)
Please try to give serious answers that are easy to process by computer (see the introduction). And please let me know as soon as possible if there are any security problems (people other than me who can access the data) or any absolutely awful questions.
I will probably run the survey for about a month unless new people stop responding well before that. Like the last survey, I'll try to calculate some results myself and release the raw data (minus the people who want to keep theirs private) for anyone else who wants to examine it.
Like the last survey, if you take it and post that you took it here, I will upvote you, and I hope other people will upvote you too.
I think it is generally good to avoid "other" options as much as possible.
There are a few biases related to filling questionnaires. For example, many psychological tests ask you the same question twice, in opposite direction. (Question #13 "Do you think Singularity will happen?" Question #74: "Do you think Singularity will never happen?") This is because some people use heuristics "when unsure, say yes" and some other people use heuristics "when unsure, say no". So when you get two "yes" answers or two "no" answers to opposite forms of the question, you know that the person did not really answer the question.
Another bias is that when given three choices "yes", "no" and "maybe", some people will mostly choose "yes" or "no" answers, while others will prefer "maybe" answers. It does not necesarily mean that they have different opinions on the subject. It may possibly mean that they both think "yes, with 80% certainty", but for one of them this means "yes", and for the other one this means "maybe". So instead of measuring their opinions on the subject, you are measuring their opinions on how much certainty is necessary to answer "yes" or "no" in the questionnaire.
Perhaps in some situations the "other" option is necessary, because for some people none of the available options is good even as a very rough approximation. But I think it should be used very carefully, because it encourages the "I am a special snowflake" bias. For example, if someone has no sexual feelings at all, then of course the "monogamy or polygamy" question does not make sense for them. But if it is "I like the idea of being in love with one special person, but I also like the idea of having sexual access to many attractive people" then IMHO this attitude does not deserve a separate category and can be rounded towards one of the choices.
So how you do decide which options merit inclusion? Which snowflakes are special enough--or, I suppose, mundane enough? And what's the harm in counting how many snowflakes aren't, even if you don't ask them exactly what type they are?
