Why does the News only show negative things is a question i have been asked a few times and my usual response is to shrug and waffle something about bad news sells.
Until know i had no real basis but science has come to the rescue and The London School of Economics and Political Science has done the research and found that newspaper and magazine sales increase by approximately 30% when the cover is negative rather than positive.
Of course editors know this, the 'if it bleeds, it leads' mantra is commonplace but as the boffins at LSEPS explain, there is a reason why we are drawn to the negative.
The conclusion they have reached is that it all comes down to what us humans decide to pay attention to and it is evolutionary advantageous to heed negative information as the potential costs of negative information far outweigh the potential benefits of positive information therefore the brain is predisposed towards focusing on negative information.
News content is predominantly negative because humans tend to be more attentive to negative information and as long as that continues the lead stories on newspaper front pages and the lead stories on broadcast media will always be a negative one to grab the readers or viewers attention.
Thanks science, you came good yet again.
