So I turn to examining your sources. I've been tripped up in the past, (and so have those around me who admit it with varying degrees of honesty!) by facts changing, or not being as first presented, or having reacted on the basis of a theory or a principle, finding that our opinion simply doesn't fit the facts.
This can result in the amusing spectacle of someone trying to reduct and argue their way out of the situation, or if they have slightly more humility and maturity, simply admitting they were wrong or like one of my heroes, John Maynard Keynes said, much better than I:
"There is no harm in being sometimes wrong — especially if one is promptly found out."
or, if the situation changes or has changed:
"When the facts change, I change my mind. What do you do, sir?"

What stands in the way of politicos doing the same thing? Two things - fear of our over-powerful media and and the baying mob of public opinion called Twitter, but moreover I think something closer to home - pride.
Pride prevents us backtracking. Pride prevents us doubting our own "rightness" enough to do some research and some understanding of what lies behind what we have been presented with - for you must always remind yourself that there is some interest for the presenter in whatever they are presenting you with - or they wouldn't do it.
Lifehacker's article says:
" One thing I like to do before I write about or share any news article that's based on a study of some kind is to see if I can get to the study itself. Is it mentioned in an article, or did someone say "a study said X?" Fire Google back up and include the journal name and publication date, if you can. "Include "research" or "evidence" or "study" in your search terms. With enough digging, you will often find several scientific papers related to your topic," McRaney suggests. Read the full-text if it's available, or at least the abstract. It'll help you get a picture for what the study really concludes."
Finally:
The more I experience in politics the more I think that there are two types of politician - those who genuinely want to make a difference, and egotists. The first group are actually far more prevalent than you would think, and the second group are very good at pretending they are not. But I'd say it's also a very good test of character... learning to test your opinion against others, how you react and argue, and moreover how you respond if wrong (or indeed right) can tell you a lot about people....
Right, that's probably enough deep thinking for this weekend, off to the Stone Roses..... enjoy!!!
