Pessimism/Optimism Survey

Only 3 questions? It seems a little weak for a survey. I mean, how much of your conclusion are you going to be able to base on solely those questions? I think some more variety, such as if they believe in Murphy's Law adamantly, are they always being very careful, or whatnot can improve the quality of the data, unless this is something that isn't that serious a data project.

*I answered them regardless, so you got one survey to evaluate.
