It may be difficult to actually decide which makes the most sense to donate to to maximize signaling (especially because doing so consciously can itself be difficult). Moreover, if one is trying to maximize signaling it may make sense to donate to a bunch of different causes. And some degree of signaling and fuzzy-buying is likely mediated by one’s peer group, so if one spends time on LW or in closely aligned circles then CFAR and SIAI may be effective places to purchase signaling credibility with the people one cares about.
