根据下面资料，回答26-30题 <br /> Demographically uniform newsrooms have been producing uniformly homogeneous content for decades. "There has been so much focus on digital transformation in recent years that the question of diversity has had to stand aside," according to a study comparing diversity efforts. And yet, as the study discovered, diversity is at the very core of audience engagement today. <br /> Before digitalization, journalists didn't have to think about their audiences as much as they do now. Newspapers were money-printing machines—the advertising dollars poured in regardless of what would now be called "content." Likewise, public-service media faced almost no competition. But now that digital information is a commodity, with a few major platforms controlling its distribution, audience loyalty has become a matter of survival. <br /> Many newsrooms were entirely unprepared for this new reality. They don't even know who their potential new customers are, let alone how to reach them and win their trust. The problem is not just that newsroom homogeneity results in an incomplete view of the world and of the reading/listening public. It is that even when "outsiders" do land a job in this kind of environment, they tend to adapt to the dominant culture rather than challenge it. <br /> The lack of diversity in the media has actually worsened in recent decades. Back in the heyday of local news, newsrooms were no less white or male, but being a journalist at least didn't require a university degree—only a willingness to dive in and chase leads. Yet as the industry became concentrated more in big cities and employment prospects elsewhere diminished, education became yet another entry barrier. While the better-educated candidates moved up to higher-profile jobs, many others left the profession altogether. <br /> In keeping with the industrial society of the time, the occupational model that followed from these changes was hierarchical. As with teachers and their pupils, and experts and the lay public, education conferred status and authority upon journalists. The public was a passive recipient of information, not an engaged participant in a broader conversation. <br /> Clinging to this hierarchical structure is now a recipe for failure. The digital world of information is one of choice and abundance, but also of considerable confusion about what is true and false. Trust is a news organization's most valuable asset, and the task for journalists is both to challenge and inspire their audience, and to invite conversations among them. <br /> That can't happen unless journalism represents the society in which it is operating. <br /> Unfortunately, a recent global survey of media leaders finds that while editors see progress toward gender diversity, much more must be done to achieve racial and political diversity, as well as a balance between "urban" and "rural" backgrounds. The most likely reason for this failure is that industry leaders continue to regard the digital transformation as a matter of technology and process, rather than of talent and human capital. <br /> The author suggests that journalists
