How's that working out for the people in Flint? They still don't have clean water. Is it like the fairy in Peter Pan where if you believe hard enough the people in charge will magically become competent?
Obviously there are limits but having your water tested from time to time isn't bad advice.
Another thing I do is test my kids toys for lead, and it comes up positive roughly 1 out of 15 times. I could trust that the government and the big box store makes sure that never happens, maybe you do, but I do science so I can know instead.
Knowing > Trusting
