How Do Financial Investors Make Choices?

Let's assume a somewhat unsophisticated, though intelligent, investor. Do these investors make decisions to invest significant dollars in up-starts based on job commitment announcements by politicians? A Butler University economist thinks so. I'm skeptical - I would like to think that even the most unsophisticated, risk-taking investor would not make a decision in large part or solely based on the words of politicians. And, I certainly know of no study that shows otherwise. For his part, the Governor suggests if some investors do make decisions based on politicians' hopes, that's their own problem. Discuss.
