I constantly find myself using the term ‘red flag’ whenever I notice something suspicious. I’m not at all sure many people know what I mean when I say it, though.

I’m reading an excellent book on critical thinking by Christopher DiCarlo called How to Be a Really Good Pain in the Ass. I heard an interview with him on Freethought Radio (I’m sensing a trend), and I thought I’d check it out. I didn’t find too much stuff online about the book, so I’m posting this talk. It’s pretty long, but it presents the main questions he raises in his book: How do humans go about investigating truth claims? What’s the difference between natural and supernatural worldviews? It’s top-notch skepticism and enjoyable reading. Check it out.
This is an awesome optical illusion which serves to teach us a little lesson not just about homeopathy, but everything else as well.
