I did a bit of fact checking of some claims myself. The all fall into three categories.

1. Misreading a graph

2. Not knowing enough statistics to be able to make sense of something that can't easily be represented in a simple graph.

3 lying.

I checked about 10 claims and most of them were in category 1. Kinda depressing.
