There are many aspects of Chapter 7 that are valuable to this study, not the least of which is identifying the limits of the effects of press freedom. One of the advantages of presenting research in a longer monograph, such as this book, is that these limitations and null findings can also be presented. Publication outlets with briefer formats, such as journal articles, tend to be heavily biased toward positive results and findings that support hypotheses. Consequently, it is often difficult to bring findings of "no identifiable relationship" into the early discourse on a subject or topic. These null findings, however, are crucial to the development of the conceptual and theoretical foundations of a research subject. In trying to puzzle out the mechanisms that link an aspect of politics or society with the larger political or social context it is just as important to know what does not work, what does not produce results, and linkages that do not exist as it is to know what does.
For this study, and for the overall effort to introduce or enhance the scholarly examination of the influence of press freedoms on foreign policies and international politics, the combination of strong findings, indeterminate findings, and null findings are particularly informative. The empirical results in Chapter 7 suggest that press freedom in other countries does not have much, if any, effect on the levels of coverage free press news outlets devote to those countries or events in those countries. This is something that would have been difficult to discern from just the
