We often use the word ignorance when we talk about people who choose to ignore advice and guidance. A better word is amathia.
Its meaning is disputed but is more about wilful blindness, and has been defined as the opposite of wisdom.
Ignorance is not knowing; Amathia is not learning. It’s OK to be ignorant – it’s not OK to be amathic.
Andrew JAcobs
It’s not bad to have an opinion on how improvements might be made to work.
It is bad when you’re so wedded to your opinion by circumstance, employer, or commitment you refuse to consider evidence which contradicts your world view.
