Chapter 6 deals with national newspaper effects, especially the claimed influence of the Sun over the voting behaviour of its readers. The associations between newspaper reading and political attitudes and behaviour over the past decades is traced, together with the popular claim that the media, notably national newspapers, set the election agenda for the population. A large body of research finds little or no evidence of strong newspaper effects on party voting and national election agendas. Instead we find strong effects of the normal demographic variables that are usually associated with many forms of social and political behaviour – the standard model of the behavioural sciences.

In this chapter, we provide a critical appraisal of the presumed correlation between investment migration and foreign direct investment. Could it be that investment migration is not as effective a form of FDI as has been presented to us? The devil is in the detail, as is always the case. However, it is clear, if we read between the lines in the official statements made about them, that many such programmes are not well designed to attract FDI – the British Tier 1 (Investor) visa could be an example.

Combinations of different inputs, when not correctly handled, are a frequent cause of faults in software. Decision tables allow the tester to identify these combinations, and further improve the test coverage. Building on the knowledge gained in the previous chapters, this chapter explains how to identify casues and effects, build a decision table, and then use the rules in the table to develop test cases and automated tests.
