Prefer to change the code rather than write a workaround

Yes! And I blame OOP.

People are taught that everything should be a magical black box, designed so well that after implementing it - you never need to change it, only add to it along the predefined extension points. So if that's true - even modifying the base classes in your own system feels "wrong", never mind the "other people's code".

I feel engineers tend to convolute the codebase by adding tons of unnecessary code instead of just modifying the existing code to work.

Another thing that has been plaguing our industry is tons of if statements to cover edge cases instead of thinking about the ways you can avoid them by writing proper logic and general equations.
