We had two groups, one vegetarian/vegan, and one omnivore.
I'm the PI (supervisor) on the replication of the creatine trial. We have finished the trial but not the data entry+analysis. Extremely tentatively, it looks like the effect replicates but with much smaller effect size. If this result remains after data entry+analysis are complete, then I'd say this is a positive update for cognitive benefits of creatine --- given that the prior for this to work was pretty low (publication bias, and so on), I'd say that one trial with a large effect size and one with a small effect size is more convincing than just one with a large effect size.
But really, the result might still change in the process of us double-checking things. It's just my best guess right now. The preprint will hopefully appear in the course of the year.
Great answer, thanks!
Thanks for all your answers :-)
I struggle to understand the difference between #2 and #3. The prosaic AI alignment problem only exists because we don't know how to make an agent that tries to do what we want it to do. Would you say that #3 is a concrete scenario for how #2 could lead to a catastrophe?
