This is shaping up to be the worst semester yet, so I need a distraction.
It’s time for some horror movies! My goal will be to watch one per night.
I’ll post reviews on Letterboxd as time permits (boxd.it/4WE5j).

This might be the first time I’ve seen someone present the base rates while directly ignoring them.
White House Deputy Press Secretary seen here posting data showing how much more prevalent right wing domestic terrorism is than left wing domestic terrorism... while thinking she's showing the reverse.
Apparently she can only read headlines, but not the actual graph with the data.

Today I started my grad cognition class for our masters program (we’re on a quarter system).
After introductions, I start with a brief historical consideration of cognitive psychology. I note that the Gestalt school was a cognitive approach based in Germany.
