Anyone who studies marketing will tell you this:
The accusation has greater influence than the truth. Here is an example. Lets say your favorite news paper published a story about your president / prime minister that he/she was having an affair. Lets imagine for a minute the whole article was completely untrue. However most of the public would read it. The next day/week the same paper publishes a lesser important article stating that the affair was completely false, and nothing happened. A logical man might think, oh well the public will read the follow up and the person would be completely vindicated. Not the case. It doesn't matter what bull-dust gets published. People lately read the headlines and spread that as "truth". When they can't prove something, they'll think "No smoke without fire, something must be up"
The problem is marketing companies have figured out how people think, how the brain works as a tool. How it processes and stores information, and importantly how it recalls information.
For example: Assume you know nothing of a certain country called XYZ, now lets say you watch just 1 documentary on, for example the AIDS crisis in that country. A week or 2 after watching this documentary, if you were in a conversation and someone mentioned this XYZ country, your brain would immediately recall the AIDS crisis in that country. Any positive achievements that may be going on in this country would be over shadowed by your prejudice from that documentary.
Same is true about
vaping. People hear "anti-freeze" from one dodgy test, everytime they think E-Cig, they think Anti-freeze. But word of mouth will prevail. More and more people are starting to
vape, and in the spirit of twisted sister - we aint gonna take it anymore!
Lastly - remember the so called Swine Flu crisis? You would think people would learn their lesson, and stop trusting main stream media, but no. Suddenly that just disappeared off the news and everyone just forgets, continuing to trust news media, I guess it's because everyone wants to feel normal. I stopped trusting news media such as CNN a long time ago, I had a friend who was originally from Bosnia during the 90's whose father was a dentist, he joined our school, and he was completely shocked by what CNN were reporting, he told me its completely false. If you want some food for thought read this, my take on Swine Flu:
