On the other hand, I came here to suggest that knowledge of Simpson's Paradox (https://en.wikipedia.org/wiki/Simpson's_paradox https://en.wikipedia.org/wiki/Simpson's_paradox) could resolve a lot of political fights. And Simpson's paradox is only applicable when data is presented as percentages, so the key to unraveling the paradox is to show the absolute numbers and changes, instead of the percentages. The real problem is that percentages hide the size of the groups, and even if you show the sizes of the groups separately, focusing on the percentages still obscures the reality unless this is called out explicitly.
