We live in a world of information explosion or pollution.
It gets through you whether you want it or not. One does not have time to evaluate whether the information passed on can be verified. Verifications can also be bought to prove one’s point.I have attended big conferences where false data is being promoted in the best packaging possible. I have attended small family gatherings and found false data floating around.
Only direct observation and NOTHING else can help you wean out true from false. Do not deprive yourself from the fruits of direct observation.
