In regards to deductivism and the work of Karl Popper, it's possible to deduce statements which are consistent with science's current understanding of something. These statements are hypotheses and some are testable, and hence scientific, and others are not testable, and hence they are unscientific. It seems to me in economics the profession is fond of deducing many statements from their models which are untestable. What is the purpose of this exercise? What can be the goal of deducing untestable statements other than to eventually arrive at something which is testable? Is there a word for these untestable statements besides "unscientific hypotheses?" Thank you.
