Good Critical Thinking Skills Exercise

We're meeting online these days - please join us! We usually have about 6 - 9 people at each meeting, and we bring information from things we've read or seen during the preceding week to discuss. Have you read a good book or article? Watched a though-provoking video? Please bring insight to share.
The link to join us online will be published just before the meeting starts. See the meetup page for that link.
BTW, most of our regulars don't sign up through meetup. It looks like nobody attends, but that's not correct.
Hope you can join us!
