There is only so much analyrics a person can do. I can do my research when it comes to my immediate proffession, and my interests. But there are only so many hours in the day, rely on the rest of society to get it right when it comes to other aspects of my life.

I cannot question everything i was ever taught in school. I have to assume that the basics physics is correct, that the fire safety and contruction people do their job, and that the doctor doing ths blood test knows what he is doing, etc.
