I listened to a great conversation this week with Russ Roberts and Adam Cifu, MD. They spoke about Cifu’s recent paper, The Case For Being a Medical Conservative which takes a good hard look at evidence-based medicine.
Cifu said two things that had clear parallels to investing:
1- “Should evidence come with an expiration date?”
2-“Once we take a drug which looks great in the lab and put it in a human being, boy it’s a different game.”
His second point is perfectly captured by this tweet from Corey Hoffstein.
“What is overfitting?”

Would you want to bowl competitively against this robot?
You don’t see the computers when you press buy and sell at TD Ameritrade, but they’re a part of the machine. In the words of Adrian Balboa, “You can’t win!”
I saw Spider-Man: Far From Home. If you liked the first one, well I guess the seventh reboot of the first one, then you’re going to love this. They picked up where The Avengers left off and didn’t disappoint.
I still haven’t started season 2 of Dark because I just haven’t gotten around to it. In the meantime, my wife started watching Dead to Me and I jumped in after a few episodes (easy to catch up). It’s pretty good. And each episode is around 25 minutes long which makes a decent show 40% better. I’d put this in that category.
Bill Gurley was on Patrick’s podcast this week and they were talking about how much money there is searching for great ideas. Gurley said something to the effect of how hard it is to come up with new and I couldn’t help but think of that when I saw this tweet today.
