We are generally more forgiving of human than (an equivalent) algorithmic error. However, in contexts where using an algorithm is the norm, this effect is attenuated, dissipates or even reverses and we would rather retain the algorithm for future use. www.cambridge.org/core/journal...

🆕 publication: In a behavioural experiment, where surgeons indicated their preference for total vs partial knee replacement, habitual practice (proportion of partial over all knee replacements in a year) was a stronger predictor of their preference than most clinical factors tested.

Scientists, given more time and flexibility, often stumble upon unexpected discoveries—like Alexander Fleming, who saw a mould had killed the bacteria he was growing, paving the way for antibiotics. Recent study analysed such findings—more of them than you'd expect. 👉 www.nature.com/articles/d41...

Predicting survival is fraught with uncertainty. This may not weigh much against giving patients choice but it is an interesting problem for those studying forecasting and preference elicitation. Does anyone know which 2023 study she is referring to (para 7)? www.ft.com/content/241a... via @ft

On assisted dying, are we really any good at predicting survival?
Forecasting the last seven days of life is harder than the final 24 hours; beyond that, things become shakier still

FOMO and last minute change of mind - it looks like I'm going to New York after all (sjdm.org/programs/202...)! I wonder if I can re-instate the poster I withdrew only last week. I may study decision making but I'm rubbish at making decisions (and sticking to them).

Thread for those new to BlueSky. First of all, welcome. It feels like a safer space, doesn’t it? But also perhaps a bit disorienting initially? Here’s some tips for getting your bearings.
