“CDC estimates Ebola epidemic could be over in Liberia and Sierra Leone by January!”
So ran the headline of exactly no news outlets. Instead, a typical headline ran the following sort of dire prediction: “Ebola cases could reach 1.4 million within four months, CDC estimates.” Only a few went with what is arguably the fairest sort of headline: “CDC offers sharply differing forecasts for Ebola epidemic.” I would suggest that, while on its face the more dire headline is somewhat deceptive and driven by bad journalistic practices, it is all things considered preferable to the alternatives.
The first two headlines are reasonable, if incomplete, summaries of findings from a recent CDC report projecting the likely trajectory of the Ebola outbreak in Liberia and Sierra Leone. Based on trends from August 31, the CDC produced two estimates: one based on what would happen if the conditions from August 31 continue indefinitely (1.4 million cases), and another based on what would happen if treatment and quarantine measures were effectively propagated (the epidemic ends). It is important to note (as some of the news articles do) that these measures have been ramped up since the CDC’s data was gathered a month ago, so the worst-case scenario is not clearly a ‘status quo’ estimate any longer. Emphasizing only the worst-case scenario is deceptive because it obscures the central nuance of the CDC’s report, giving the impression not that 1.4 million *might* contract Ebola, but that 1.4 million *will*.
So, why do news outlets typically choose to emphasize the sensational worst-case scenario?
