TL;DR Summary

• Propaganda poster distributed on social media notes that the number of Americans killed annually by “Islamic jihadist immigrants” is very small.
• The numbers in the chart appear to be approximately correct (depends on year and who is counting).
• The poster uses data, which may invoke System 2 rational thinking, yet the numbers and layout are simple enough that many people may process this with their quick, intuitive and emotional-based System 1 thinking style. In that regard, this is an effective propaganda poster.

I checked some of the numbers in the table and they were approximately correct. This does not mean the data is accurate as I did not check all of the items, nor did I look in detail at how the tally was made in each category. The point of this post is to illustrate the use of data in a propaganda poster. Most propaganda is designed to appeal to emotions and is typically devoid of data. However, the data here is simple enough that it may be engaging a System 1 emotional response rather than rational, analysis response.
