Hmm, I was raised with uncertainty and naturally talk about it with children. Most extensively with my nephew. We had a lot of long conversations about The Magic of Reality while he was reading it.

Agreed.

We had a book of little experiments when we were kids - you know - get the egg sucked into a bottle sort of things? I think this helped with knowing that some things are very concrete and some aren't. Also a chemistry set.

I don't know if we're teaching critical thinking skills at all? I'm pretty sure I learned mine at home. And by reading - a lot.

Some of my biggest mistakes have been some of my biggest learning experiances

This is so very important. So many people are terrified of being uncertain or the possibility of being wrong. The ability to admit that you don't know an answer is the first step to finding that answer.

Absolutley agree. We should teach children that there is a difference between 1 the truth, and 2 what you might want the truth to be. Children are taught over here in the UK to supply evidence for an argument, what is not encouraged enough is to scrutinise evidence, to see if it stands up to scrutiny.

Theories should be stated as such and not Facts. Theory as of now sounds more intelligent.
