Recently, the Oxford Dictionary chose “post-truth” as its 2016 Word of the Year. It was first used in a 1992 essay in The Nation. They define it as referring to “circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.”
I personally believe that “the public” has come to equate knowing the truth to getting bad news. We are tired of bad news, so we are tired of the truth and now want to be protected from it. The problem with this is that anyone and everyone can manipulate us without having to work very hard. They don’t need to suppress the truth, they just ignore it and tell us whatever will make us happy … and give them what they want.
