What's the utility of logic?

Logical thought is by definition thought that is truth-conducive, i.e. likely to lead to true conclusions when given true premises. So the utility of logical thought is identical with the utility of true belief. What is referred to as ‘logic’ in universities is not logical thought but rather very simplistic and fragmentary models of such thought—-in much the way that what is referred as ‘economics’ in universities isn’t so much economics proper as it is certain people’s theories (or models) of economic behavior. So the utility of logic classes is more or less nil—but not because logic per is useless, but rather because they aren’t really about logic. The utility of logic itself, i.e. of thinking logically, is self-evident since it derives from the utility of true belief.
