You all complain, but it's not easy.

http://backreaction.blogspot.it/2017/03/academia-is-fucked-up-so-why-isnt.html

Should we give up do science? Should we close wikipedia?
Should we distrust wikipedia or science?

I recently read an article in Italian that talk about anti-vaxxers[1].

Roughly it says they are middle class and they should have access to the 
tools to build up an informed opinion.

For me it is absolutely clear what herd immunity is and I've no doubt 
vaccines have an historical successful record.
But I'm not a doctor! Am I qualified to draw this conclusions? Why or 
why not?

Nevertheless I do believe media and even experts lies and there are real 
conspiracies oh!

I think the usefulness of Occam's razor has been excessively simplified ;)

BTW Rick, feel responsible for making me waste some more time to try 
again to replace fetchmail.
