 It is crucial to note that the issue of whether intellectual property protection does, or does not, sufficiently promote human happiness or well-being is an empirical question. Whether or not, for example, intellectual property protection provides an incentive that elicits some optimal output of content creation can be settled only by looking to the empirical evidence. Likewise, whether or not intellectual property protection has the effect of hindering innovation and inhibiting the production of novel valuable content can be settled only by empirical analysis. The difficulties involved in obtaining such evidence suggest that the empirical question will remain debated for some time. Complicating the task is the fact that the efficacy or lack thereof of intellectual protection in promoting well-being seems to vary from one industry to the next (Lemley 2015).
