Rare use of data in an effective propaganda poster
This is from Bill Gates. I have not vetted the content of the chart, but I assume it is true and correct. TL;DR Summary The point of this poster is to illustrate R&D spending on 3 categories: Defense, health and energy. It is effective in part due to its simplicity and use of data. Data is not used often in propaganda posters because emotional appeals and pithy quotes are processed quickly by our System 1 thinking.
