But that is the first reason. Apparently putting a number in the headline increases your click thru rates (through is so old school journalism) by 23.4% (I made that up, but in journalism today you're allowed to do that because there's always some snippet of information out there that will back up this or any other statistic.
Of course, journals are now performance monitored machines who are valued based on the numbers of views they can harvests for their vast media conglomerates. As the recent UK election shows, any kind of deviation from the presumed reality is not countenanced, and even quantitative based reporting is likely to be wrong.
It wasn't the political class that had their world torn up before their eyes over the past few weeks, it was the media class, and journalists in particular.

The journalists' currency used to be words, now it's clicks and audiences.
