Even assuming that either DR’s popularityor AD Lid’s campaign, or both, were responsible for the Megalopolis success,the manager’s calimthat this success can be repeated elsewhere might nevertheless be unwarranted.Megalopolis mightnot be representative of most cities in which DR plans to appear—inany one of various ways that would adversely impact ticket sales in othercities. Forinstance, perhaps DR hails from Megalopolis and has far more fans inMegalopolis than any other city. Or, perhaps the kind of ad campaign that is Ad Lib’sspecialty, although effective in Megalopolis, would not be effective in mostcities.

Even if I were to concede thatpollution caused Yosemite’s amphibian decline, this single sample is insufficient to draw anygeneral conclusion about the reason for a worldwide amphibiandecline. It isentirely possible that the cause-and-effect relationship in Yosemiteare not typical of the world in general. Without additional samples from diverse geographiclocations, I cannot accept the author’s sweeping generalization about thedecline of amphibian and global pollution.

The memo unfairly assumes that sinceVenadial is popular in Alta it will also be popular in other countries. Consumer tastesin foods like margarine, as well as concerns about health matters such ascholesterol level,vary widely from country to country. It is quitepossible that consumers in Alta enjoy the taste of Venadial morethan other consumers would, or that consumers in Alta are more concerned than the average personabout cholesterol level and heart attack. Since the memo provides no evidence that tastesand health concerns of Alta consumers are representative of those of people generally,the sale’s director’s conclusion that Venadial will be popular elsewhere isunjustifiable, at least based on the memo.
