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.

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.

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)?

On changing the rules - not the players.
We should focus on systems and policies (S-frame) and not just individuals (I-frame). This has implications for methods, as RCTs are not fit for systems-based interventions, and instead, we should focus more on quasi-experimental methods
