Grant peer review costs a lot: ~$40k per application in reviewer time, with proposals reviewed again and again. In @thetransmitter.bsky.social , I propose a partial lottery: reviewers decide pass/fail, chance picks among the passes, and "unmissable" ideas and ECRs get protected routes.
thetransmitter.org
How about adding an element of chance to grant review?
A process that uses a lottery system saves time and accepts that, above a quality threshold, luck has always played a part in science funding.

🗓️ Join me on October 7 for one of the inaugural lectures of the Science of Intelligence Institute #UCBerkeley. Can we write scientific laws for intelligence? I believe that we can, that the math for it already exists, and that they apply across brains & machines. Let's chat: tinyurl.com/mvrfs39w
