If you have studied or work with numbers, components shift from system 2 to 1 depending on your experience.
I, too, just had to glance at 550 to know it was 250+ since 500/2=250 and that fact is just baked in there somewhere without me needed to think about division. And since it’s the same thing again with the 50, it doesn’t take more than a fraction of a second to do 250+25…
Basically “System 1” is intuitive gut responses, while “System 2” is anything that takes conscious effort to think through.
For a lot of people, 550/2=225 might look right at first glance (System 1) and only with conscious thought at what that division actually evaluates out to would they realize that 500/2 on it’s own is 250 and therefore the answer is actually 275 (System 2)

But my system 1 never thought 225.
What systems are you talking about?
It comes from here: Thinking, Fast and Slow
TIL the book is pretty recent-ish. I thought I read it ages ago.
