Perun, I think I know you as a very critical thinker. I also understand you have an urge to test yourself.
But man, to doubt virtually every fact that is reported. To (almost) constantly mistrust media, that sounds more like the life in a warzone, or in the old DDR, or Iran or Russia or other countries using propaganda and means to limit freedom of speech. How can some watchblogs make you so utterly disillusioned that it has come to this?
Back to the critical thinking. I think you can use your own critical thinking in your advantage, by first judging yourself if something is to be trusted or not, and afterwards all these quadruple checks can always be done, if you feel uncomfortable about something. Why not trust your own judgement first?
