people are needed in fulltime employment. More and more people are working from home using personal computers, which can result in a sense of isolation. Home workers also lose the stimulus that comes from working in direct contact with other people. Another example of the negative effect of technological change can be found on the domestic front, in the home. In my view, technological developments such as the microwave are devalueing traditional homemaking skills like cooking. A final example comes from the area of information technology. More facts about individuals are being stored in data banks, which may be accessed through networks of computers. This creates an everincreasing risk of accidental or deliberate leaking of private details. Every day more information is collected by banks, credit card companies, consumer organisations and so on and who is there to keep an eye on what happens to it
My friend travels quite a bit and often finds himself chatting with strangers in bars, restau- rants, and airports. He says that he has learned through much experience during these conversations never to use his title of professor. When he does, he finds that the tenor of the interaction changes immediately. People who have been sponta- lInstructive of the reach of the authority principle is evidence that ersatz experts are given credence in domains beyond medicine and homemaking. For instance, in a January 24, 2001 TV interview with actor Martin Sheen, host Brian Williams pursued a line of questions regarding Mr. Sheen's views of the appropriateness of presidential decisions to accept gifts and to pardon criminals just before leav- ing office. Mr. Sheen dutifully offered his opinions even though his relevant experience to that point was limited to playing the role of a U.S. president on the TV series West Wing.
