Sure, we are careful to keep her included in all conversations regardless. Also there isn't much going over her head and she loves to change the subject with a joke which amuses me the most.
That depends on the child. I'm having deep and engaging conversations nightly about these recent events with my 13 and 9 year old who bring it up during dinner, my 4 year old follows along in her own way and keeps up with the understanding.
My wife and I help guide the convo and but they draw their own conclusions. Critical thinking is a muscle which must be exercised and grown.
I had an over weight friend in highschool who could run really fast. He did this by basically by making his top half fall forward which caused his legs to move quickly to keep him from landing on his face.
I think this is a similar phenomenon where the people tripping up the stairs have an imbalance causing their top half to fall forward. As a result the unconsciously speed their bottom half up to catch the top half from falling.
This is an incredible read, very thought invoking.
I've never replaced stairs but I have learned enough of the "details" by repairing them (or being aware of them) to know it's a really hard to get right.
A single 1/4 inch difference between two steps can feel wrong; a 1/2 inch difference and people will likely stumble or tumble down them on their first approach. Our intuition and pattern recognition impacts how we solve problems. Some call it "muscle memory" but it's not just in our muscles, it's in our unconscious thought.
Like the author explains so well, once we move a detail into our unconscious it becomes part of us, transparent to us, "common sense"; and an unnoticed detail is completely hidden from us.
The details of reality can only be taught through experience, because once understood, they move almost instantly from hidden -> transparent.
