This is the bi-weekly visible open thread (there are also hidden open threads twice a week you can reach through the Open Thread tab on the top of the page). Post about anything you want, but please try to avoid hot-button political and social topics. You can also talk at the SSC subreddit – and also check out the SSC Podcast. Also:
1. Is anyone here an oncologist or orthopaedic surgeon who feels competent to answer some hard questions about pareosteal osteosarcoma, for a smart good person who will not misinterpret you or treat you as official medical advice? If so, please get in touch with me at scott[at]slatestarcodex[dot]com so I can connect you with a friend of mine who needs some help. They already have a doctor and are on track to get good care, they just want to get clarification on some of the evidence base around which treatments are best.
2. Tina White is looking for people to critique, collaborate with, or just get in touch with her about her idea for a privacy-aware app to track the spread of infectious diseases like the coronavirus. She’s especially interested in anyone who knows about the history of how plagues and quarantines have interacted with traditional privacy rights. See her EA forum post or Facebook post and request for collaborators for more information.
