(27,787 posts)The field of social psychology is pretty clear on the relationship between attitudes and predicting behavior associated with those attitudes.
If you want to use measures of attitude to predict behavior, you have to ask questions about a person's attitude towards performing the specific behavior in question.
Abstract attitudes, which is what a word cloud measures (and that's if I'm generous), have no ability to predict a subsequent behavior, like voting.
Election polls however, focus on asking people about their attitude towards performing a specific behavior (that behavior being voting).
If you want to learn more about what I'm describing, look into the Theory of Reasoned Action. Its one of the most complete and well studied theories in the social sciences.
As an aside ... my PhD is in Experimental Psychology ... and so my "snorting" at the silliness of the use of word clouds here has nothing to do with my preferred candidate, and everything to do with what I know about the relationship between attitudes and the extent to which those can be used to predict human behavior.
