FRESH OFF THE PRESSES from our lab (🔗rubin-lab.mgh.harvard.edu/) How does anticipated regret influence ECMO candidacy decision-making? With a team including economists, we apply Regret Theory to analyze this question and demonstrate its role in ECMO candidacy. Clinicians prefer clear-cut cases, but even then, and certainly in more gray-zone cases, fear of regret emerges: 1⃣ Regret of omission: Even if we know ECMO won't help, we will feel terrible for not trying. 2⃣ Regret of commission: Even if there's a chance ECMO will help, it's very small and we will almost certainly regret having tried when this inevitably becomes a bridge to nowhere. Many questions follow: Is regret-dominated decision-making ever appropriate? Should it be corrected for? Does it exist across critical care or medicine more broadly? This is only the beginning journal.chestnet.org/article… Thank you to Boston College Economics (@bc_econ) and @accpchest @journal_CHEST @MGBResearchNews @HMSbioethics @MGHHeartHealth @MGHHeartHealth @PCCSM_BIDMC @MGH_PCCM @HarvardPulm

🚨New working paper 🚨 How much better are we getting at manufacturing clean energy technologies? And how much of that improvement is driven by learning-by-doing? We answer these questions for wind energy. Watch this short video or read on for details.

1/ The recent letters from mathematicians (Leiden Declaration, Fields Medalists) aren't just about AI "solving" math problems. The deeper risk: commercial AI incentives may break the reciprocal loop that advances mathematics. This maps onto a framework I've been developing.
