Observation v Belief

I am still ruminating over a family conversation. I always get accused of bringing up politics, which I really don't. But I cannot tolerate talking  points or factual inaccuracies. So when talking about climate change, my little brother asserted that once upon a time, most people believed the world was flat.  Ahh, that gave me the chance to point out the difference between observation and belief.  I love science, even though I'm not anything close to being a scientist.  Here is a link explaining how some people, to justify their BELIEFS,  cherry pick science.  http://www.salon.com/2014/07/23/neil_degrasse_tyson_exclusive_i_don%e2%80%99t_know_what_kind_of_democracy_that_is_if_you%e2%80%99re_gonna_cherry_pick_science_because_it_conflicts_with_your_philosophy/
