We’ve known for a long time that the emotional content of films and television programs can affect psychological health. It can do this by directly affecting your mood, and your mood can then affect many aspects of your thinking and behaviour.

If the TV program generates a negative mood (anxiety, sadness, , or disgust), these experiences will affect how you interpret events in your own life, what types of memories you recall, and how much you will worry about events in your own life.

Why have I singled out negative news bulletins for here? Well, there is good reason to believe that the negative sensationalism in news has been gradually increasing over the past 20 to 30 years.

First, we’ll look at what negative news is, and then we’ll examine the reasons why broadcasting negative news has become so prevalent. Finally, we’ll look at some of the ways in which viewing perpetual negative news might affect your mood, and particularly your tendency to worry about your own specific problems.

There are a lot of bad things that happen in the world, and it is right that people should know about these things through reporting in news bulletins. These "bad things" include , famine, war, violence, political unrest, and injustice, to name a few.

But there is also an increasing tendency for news broadcasters to "emotionalize" their news and to do so by emphasizing any potential negative outcomes of a story no matter how low the risks of those negative outcomes might be. This is basically scaremongering at every available opportunity in order to sensationalize and emotionalize the impact of a news story.

Because we now have 24-hour news coverage, gone are the days when a correspondent or journalist’s role was simply to impartially describe what was happening in the world—because of satellite TV, we have an almost immediate visual record of what is happening throughout the world. So the journalist’s job can become one of evaluating the news story and it is only a small step from evaluating a story to sensationalizing it.

As professor of journalism studies Bob Franklin wrote some years ago, “Entertainment has superseded the provision of information; human interest has supplanted the public interest; measured judgment has succumbed to sensationalism.” Franklin, B, Newszak and News Media, 1997.

News bulletins also have to compete with entertainment programs for their audience and for their primetime TV slot, and they seem to do this by emphasizing emotionally relevant material such as crime, war, or famine at the expense of more positive material.

Knowing that the proportion of negatively-valenced emotional material in news bulletins was increasing, in 1997 we conducted a study looking at the psychological effects of viewing negative news items. We constructed three different 14-minute news bulletins. One was made entirely of negative news items, one was made entirely of positive news items (e. . people winning the lottery, recovering from illness), and one was made of items that were emotionally neutral. We then showed these bulletins to three different groups of people. As we predicted, those who watched the negative news bulletin all reported being significantly more and sadder after watching this bulletin than those people who watched either the positive or neutral news bulletin.

But what was more interesting was the effect that watching negative news had on peoples’ worries. We asked each participant to tell us what their main worry was at the time, and we then asked them to think about this worry during a structured interview. We found that those people who had watched the negative news bulletin spent more time thinking and talking about their worry and were more likely to catastrophize their worry than people in the other two groups. is when you think about a worry so persistently that you begin to make it seem much worse than it was at the outset and much worse than it is in reality—a tendency to make mountains out of molehills!

So not only are negatively valenced news broadcasts likely to make you sadder and more anxious, they are also likely to exacerbate your own personal worries and anxieties. We would intuitively expect that news items reflecting war, famine, and poverty might induce viewers to ruminate on such topics. But the effect of negatively valenced news is much broader than that—it can potentially exacerbate a range of personal concerns not specifically relevant to the content of the program itself.

So, bombarding people with sensationalized negativity has genuine and real psychological effects. Given this cascading effect of negativity into people’s personal lives, should TV schedulers be required to consider such effects when preparing and scheduling programs containing emotively negative content?
