Socialist, for example Scandinavian countries: socially permissive, high taxes, major redistribution of wealth...
Exactly zero of the Scandinavian countries (Denmark, Norway, Sweden, etc...) have anything approximating a "centrally planned economy in which the government controls all means of production". I recommend changing the term (welfare state or Nordic model might be closer to what you were getting at) or the examples (North Korea is probably the only one left that fits the bill).
If this is the definition for Socialism, what is your definition of communism? I'm haven't deeply studied politics, but I've used the word Communism to mean centrally planned economy controlled by the government, and Socialism to mean "Capitalism, with government wealth redistribution and/or regulations to steer the economy."
(In accordance with Prase's point - while I don't specifically identify as "Socialist" with a capital S, I lean in that latter definition's direction and use the word socialist to distinguish my beliefs from libertarianism and anarcho-capitalism.)
Some have been curious about what the politics of this community would look like if broken down further; here's a shot at figuring it out. I've also included a few other questions that folks expressed curiosity about. Aside from one sensitive question, there's no option to keep your answers private, since in my opinion that would defeat the point - just don't answer if you have concerns - but there's also no overlap with the old survey, aside from asking you how you answered the original politics question. (This should help with interpreting those results even if the n for this is much lower than and somehow biased relative to the big survey.)
For entertainment purposes only, don't use the below space to discuss politics directly, &c. Early suggestions are likely to be incorporated, given what I assume to be the low quality of the first draft.
Edit: "left" and "right" operationalized for the questions they appear in; poor language cleared up in mental health question.
Edit 2: results here; see comment below for some preliminary thoughts. Because there were several unique regional responses, I did not publish responses that question.
