You obviously do. It’s a pretty similar example to the classic ball & bat problem. It’s not hard maths, but system 1 basically doesn’t use maths at all. It’s pure instinct.
How would that obviously be the case? I work with numbers a lot and immediately knew 550/2 = 275, didnt need to think for the fraction of a second. The systems are not equal across different people, every mind is unique.
Small example: Would you consider 10/2 = 5 system 2? I think most people wouldnt, but ask a 1st grader and they would probably need to think for a few seconds.
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)
You shouldn’t need system 2 thinking for that at all …

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.

No you don’t, it only took one look to see that half of anything bigger than 500 needs to be at least 250.
Yes. Same as: 225×2 is not 550. Well, duh, obviously
