I agree that we don't have a clear sense yet of which interventions are actually high-impact. [...] However the appropriate response to this problem seems to be to invest in more research, to work out which interventions will plausibly be high-impact. Alternatively, one could invest in improving one's position to be able to purchase more of the high-impact intervention when we have a clearer view of what that is - putting oneself one a good career path or building an effective movement.

I definitely agree with this, and that's what I tried to articulate in the section on value of information. Sorry if I wasn't clear.
