There are a lot of facts, some may have been proven scientifically, some may be born out of a religious belief or experience, and some may just be repeated enough in mass media, robocalls, people holding up signs, knocking on your door, or gathering in large numbers and yelling at the top of their lungs.
Everyone probably has a fact they believe in or had believed in until they saw that they were wrong.
Hell, just look at Climate Change, work of God, Man, or Nature? Influence surrounding the facts, include Corporations, Political Parties, Religious organizations, Universities, PACS, Non-Profit organizations, For-Profit organizations, regions of the world, developing nations, developed nations, NIMBY, as soon as we get this ______ fixed we will look at it.
Then there are just con men and people who love jerking you around and see how many people will jump.
Have you 'Liked' someone or something today? Someone's career or business may depend on it.
I know which facts I believe in and take time to write to those in government to provide my experience if not just feelings regarding an issue. Then there is just find time to volunteer to make a difference at the local level.
..... think global, act locally.
Not to sure how careful I was in this posting.
