But there needs to be an error margin: will say it's very important to make mistakes, because they are essential for development (as a motivator to learn and to change behavior).
I disagree. It's pretty counterintelligent to allow forseeable mistakes. Still, "we" do this more often than not.
In general that's likely. But I would be very careful not to make absolute assertions. Making mistakes (even knowingly) can lead to very positive outcomes or very important learning motivations.
And when I say knowingly... sometimes we just
think we "know" it's a foreseeably mistake, but we might just be wrong about it and that it's not a mistake.
I would say making mistakes (even knowingly) is part of our natural intelligence, or maybe you could call irrational or non linear intelligence...
Just an example:
many many years ago I was 100% sure that not selling my Bitcoin after making the first 5x or 10x was absolutely a mistake.
Today I think it was one of the best decisions in my life. Where would I be now without making that "mistake"...
