Not surprisingly, Professor Waismel-Manor and Professor Tsfati found that other factors, too, influenced coverage. Senators and representatives who hailed from larger states, were male, were black or espoused more extreme ideologies also tended to be featured more frequently. The effect of attractiveness on news coverage, the study found, was greater than the effect of tenure in office, or bill sponsorship. Frequency of news releases had no discernible effect on news media appearances. The study also examined coverage on NPR and in USA Today, and it found no correlation between the so-called attractiveness effect and coverage in those outlets.
