If our thoughts do, in fact, fabricate or alter parts of our brain structure, then we have to develop a more personally responsive model of how we deal with information being presented to us.
The mainstream media has known that we can be altered according to hype and sensationalism for decades. This is why, at the end of news broadcasts, we get the 'feel good' story: to give the viewer a rush of dopamine to off-set the adrenalin and other stress hormones from watching the bad news. The TV news programme is also read by attractive 'eye candy', which hooks the viewer by shooting straight for the libido as soon as the credits and dramatic music fades out. The reason why the main TV newscasts are at regular times during the day is because we need regular adrenaline and dopamine medication. This is not done by accident. This is all planned and all designed to turn the viewer into a junkie in search of a constant fix.
When it comes to 24-hour news channels, the effect is somewhat different. A sense of dependency on information is cultivated in the viewer; that some really important event might 'break' at any moment and will be of vital importance to the audience. In this situation, a sense of hypervigilance is the key to maintain the audience. The flashing 'BREAKING' logos which continually appear on the screen keep the viewer 'tuned in'. This is only possible using hype and sensation, and this is a co-dependency we all have to break free from.
