[Linkpost] “Research: People do not allocate enough resources to risks with lower probability of survival” by Adam Elga

This is a link post. [Study authors: Adam Elga, Jian-Qiao Zhu, Thomas L. Griffiths] Summary: When asked to divide a fixed budget to fight several independent existential risks, experimental participants did not allocate enough resources to the risks with lowest probability of survival. Excerpts: if we face catastrophes with survival probabilities of 4% and 40%, it is more valuable to increase the probability of surviving the first catastrophe from 4% to 9% than it is to increase the probability of surviving the second catastrophe from 40% to 80% (since we care about the product of the survival probabilities and 9% ⋅ 40% > 4% ⋅ 80%). This dependence of optimal allocations on baseline chances of survival is a distinctive and somewhat counterintuitive feature of situations in which incentives are multiplicative (Lewis et al., 2023; Lewis & Simmons, 2020).
