Since there's taboo around this, suggesting that cases of Andes virus may be caused by human-to-human transmission on a cruise ship is entirely uncontroversial: 1️⃣ We already know it's able to. 2️⃣ Conditions are "optimal". 3️⃣ This doesn't change the fact that a larger outbreak is extremely unlikely.

📣 The difference between replicable and not replicable is not itself scientifically replicable. 📣 New work with Erkan Buzbas, showing that verdicts such as "X% of results replicated" are based on an inferential machinery that doesn't work.
