> We dedicated a team of ~5 research staff to work full-time for 2 weeks for each top charity.
> The majority of this dedicated team did not have significant experience investigating these areas, giving them the advantage of a relatively unbiased starting point.
> An additional 5-7 researchers with more expertise in these areas of our research provided support by answering questions and assessing the red team’s arguments.
So there was no red teaming. It was instead an independent analysis of the assumptions, actions and processes of the charities in question.
