The interesting thing about optical illusions is that one may be aware of the illusion, yet, it does not go away.

It seems that the lines on the picture have different lengths even though one positively knows that they are exactly the same.
Now consider this statement:
Until January 2016, all nine situations which the International Criminal Court (ICC) had been investigating were in African countries. None were in European or American countries. ICC is therefore biased against Africa.
It doesn't take much thought to realize that a country with war criminals in jail is better off than a country with war criminals at large. So, if anything, the ICC is biased against Europe and America.
But knowing that doesn't make the moral illusion go away. Read the quote again and it still feels like Africa is being wronged. Repeat as much as you want: Yep, still there. Africa is being wronged.
Picture fixed. Thanks for spotting that.
That's the nature of illusion: If you research it there's no illusion. If you just glance at it without much thinking, the illusion is there.
As far as I am aware, yes. At some point it was all about Africa. I recall complaints about that in the media back at the time.
