A crucial point in analysis , something that is missing from what people write and believe in, is to check sources. Many websites will quote unattributed experts as the source of their unverifiable information, and of course states use the excuse of security secret sources, and to me these sources should be looked at with great scepticism.
The second level is that of the press and others cherry picking their evidence
The third level is of the misleading attention grabbing headline but when you look at the details of what is reported in the original sources, you find that the message has been distorted or selectively interpreted.
That is why one always has to check the sources of the information and look at original sources where possible, and selectively try to look at peer reviewed scientific material where science is concerned. And I guess this inbuilt healthy scepticism and checking of sources is one of the main cornerstones of scientific training.
