The recommended distribution between the four focus areas of effective altruism is as follows:

Can someone please show me where the scentific reasoning behind this particular distribution is justified in discussions, presentations, or litterature?
Does it follow the logic used here by Benjamin Todd (80.000h) and here by Robert Wiblin (80.000h)? Or is there more to it?
I hope you enjoy your summer!
Kind regards,
Peter
I have a few responses to this:
Actually answering the question, I don't think there's any reason to assume that whichever EA Funds staff member selected the default allocation thinks that this is the theoretically optimal way to allocate resources – in fact I think that's very unlikely. So the real question is what higher-level method, if any, was being used to select that allocation.
I don't think anyone except a member of the appropriate team at CEA can answer that. Have you asked them?
Nice, thanks Peter.
Seems like a good reason. :-)
