Why we can't explain what we choose?

Choices are split into two categories - Reasoning system / automatic system
Choice blindness is when you made a choice but don't know why because you didn't think about it in the moment,  like why you stepped on that part of the footpath, why you ate that type of food - unaware of why you made the choice - when asked you'll be justifying only, rather then recalling why because you never thought about it in the moment. This is why we make mistakes and have no idea why we did it - bosses should learn this psychology lol the only way to cause less mistakes is for people to think more before making choices.
