" One attempt to address the first defect is known as grand unification. The so-called grand unified theories (GUTs) hypothesized that the SU(3), SU(2), and U(1) groups are actually subgroups of a single large symmetry group . At high energies (far beyond the reach of current experiments), the symmetry of the unifying group is preserved; at low energies, it reduces to SU(3)×SU(2)×U(1) by a process known as spontaneous symmetry breaking. The first theory of this kind was proposed in 1974 by Georgi and Glashow, using SU(5) as the unifying group. A distinguishing characteristic of these GUTs is that, unlike the Standard model, they predict the existence of proton decay. In 1999, the Super-Kamiokande neutrino observatory reported that it had not detected proton decay, establishing a lower limit on the proton half-life of 6. 7× 1032 years. Model Plus Size This and other experiments have falsified numerous GUTs, including SU(5). Another effort to address the first defect has been to develop Preon models which attempt to set forth a substructure of more fundamental particles than those set forth in the Standard Model. "

" [. . . ] [Y]ou take the examples they select to prove their position [. . . ] and you look at those examples to see whether they follow the Propaganda Model. Model Virtual" (Understanding Power, 18f; emphasis in the original) And so the book studies the examples regarded as paradigmatic examples of the independence of the press, such as the Vietnam war, Watergate, and the Iran-Contra Affair, and argues that these examples actually confirm the model. They also looked at what they perceived as naturally-occurring "historical control groups" where two events, similar in their relevant properties but differing in the expected media attitude towards them, are contrasted using objective measures such as coverage of key events (measured in column inches) or editorials favoring a particular issue (measured in number).
