Use some basic reasoning:
* Many people are shocked and surprised by these findings
* They are sympathetic to aboriginal causes and not sticking their fingers in their ears. They were not trying to avoid it
You are in the educated set (university), work for the government, and are commenting on a text based forum so you probably easily consume and retain text based information. You also had a school that taught death stats specifically (mine didn’t) and are young enough that these stats were known at the time the curriculum was formed.
If most people were like you, these findings would not be headline news. The fact that the finding are surprising sympathetic people should indicate that you’re not the majority.
And it is not fair to people to say they “choose” to remain ignorant because they didn’t pay close attention and integrate statistics at the time the truth and reconciliation report was released.
Do you have no gaps in your knowledge? In particular outside of bookish, text based knowledge, which you are surely top 1% in.
