The way we form opinions about things is generally based around how we are influenced about it. You won't find someone that creates beliefs without an influence of some sort. Influence is everything. We tend to gravitate towards the things that catch our eye. This is why visual media has such an astounding impact on us.
There are people on this earth that are fueled by attention. They are on a constant battle to get attention from as many people as possible. They want their name coming out of other people's mouths whether its good talk or bad. They need it just to get by. So they submit to propaganda, pressure, and sugar coated persuasion. It is inevitable that these people will never be who they really are.
The chemicals in our minds are released when our brain tells them to. When something that makes us happy occurs, our brain releases chemicals that make us laugh, smile, and feel good all around. The same goes with any other emotion. The media does not consist of stupid people. They are smart, they are witty, and they know exactly how to manipulate your emotions.
Everything I've ever been taught about people; everything I have ever experienced involving others has brought me to believe that no one is genuine, no one can truly think for themselves, and the media controls a very unreasonable percentage of our lives and the way we think and act.
