The Open Philanthropy AI Worldviews Contest was a 2023 competition organized to surface novel considerations that could influence Open Philanthropy’s views on AI timelines and AI risk. A total of $225,000 in prize money was awarded across six winning entries. The contest served as the formal successor to a 2022 preannouncement and as a spiritual successor to...
The Unjournal is an organisation that works to organize and fund public journal-independent feedback, rating, and evaluation of hosted papers and dynamically-presented research projects. Their initial focus is on quantitative work that informs global priorities, especially in economics, policy, and social science. They aim to encourage better research by making...
Imposter syndrome is a prevalent psychological phenomenon characterized by persistent feelings of self-doubt and inadequacy, often experienced by individuals in high-achieving environments. In the context of effective altruism—a movement focused on using evidence and reason to determine the most effective ways to benefit others—imposter syndrome can be particularly...
The California effect is the shift of regulation—such as antitrust, environmental, data privacy, and artificial intelligence regulations—toward political jurisdictions with stricter regulatory standards.[1][2]
Sometimes the expression "California effect" is used to describe the shift of regulation toward regulation introduced in California, which typically...
In moral philosophy, supererogation is the performance of more than what morality demands. A supererogatory act is morally good, but not morally required.

Urgent longtermism is the position that now is an unusually good time to have an outsized impact on the future (i.e., the hinge of history hypothesis). In particular, it claims that the current time is particularly pivotal and that we have some scope to change what happens. Ben Todd creates a distinction between two kinds of urgent longtermism: broad and targeted...
Not all causes are equally cost-effective. In fact, the distribution of cost-effectiveness is heavy-tailed: some causes are thousands of times more cost-effective than others.
Such variation in cost-effectiveness in part follows from the existence of immense global inequality, which implies that many people in the world suffer from problems that could be...

Bayes' Theorem (also known as Bayes' Rule or Bayes' Law) is a law of probability that describes the proper way to incorporate new evidence into prior probabilities to form an updated probability estimate. It is commonly regarded as the foundation of consistent rational reasoning under uncertainty. Bayes' Theorem is named after Reverend Thomas Bayes, who proved...

Effective Altruism Community Building Grants (or the CBG programme) (CBG) is a project rungrantmaking program supporting professional city and national effective altruism groups. The program was established in 2018 by the Groups team at the Centre for Effective Altruism (CEA), providing full-.
CBG provides funding to a set of established EA groups. Historically, CEA also provided non-monetary support to grantees, including retreats, regular check-ins, coordination calls, a shared Slack space, and part-timeresources for running groups.
In 2026, CEA began transitioning evaluation of CBG grants to individuals andEA Funds, where the portfolio is expected to be managed alongside, but remain separate from, the EA Infrastructure Fund. CEA also phased out or transitioned most CBG-specific non-monetary support. Funding for existing CBG groups doing local effective altruism community building.[1] It was started in 2018. continues, but the portfolio remains closed to new applicants.
Centre for Effective Altruism | Effective Altruism Funds | Effective Altruism Infrastructure Fund will start evaluating grants for some EA | Effective altruism groups, Joan Gass.
DiGiovanni offers a comprehensive list of potential objections to his argument, and their rebuttals, but heas well as clarifications on what this argument does (not) claim. He also mentions two attempts to find action-guidance despite cluelessness: i) consequentialist bracketing, and ii) a metaepistemic wager.

For example, there are some reasons to think that the long-term effects of a marginally higher economic growth rate would be good—overall good or c-preferable—say, via drivingby fostering more patient and pro-social attitudes. This would mean that taking action to increase economic growth could have much better effects than not taking the action. We have some reasons to think that the long-term effects of a marginally higher economic growth rate would be bad —for example, via increased carbon emissions leading to climate change. This would mean that not taking the action that increases economic growth could be a much better idea. It is not immediately obvious that one of these is better than the other, but we also cannot say they have equal expected value. Rather, the EV is indeterminate.
We care about the overall effects of a marginally higher economic growth rate (~P1). If we have no reason to believe that our best guess (on whether it is overall net good or bad) is truth-tracking because of substantial unawareness, we should not follow this best guess (~P2). Given how coarse our awareness of the possible consequences of a marginally higher economic growth rate in fact is, we indeed are in such a situation (~P3).
DiGiovanni offers a comprehensive list of potential objections to his argument, and their rebuttals, but he also mentions two attempts to find action-guidance despite cluelessness: i) consequentialist bracketing, and ii) a metaepistemic wager.
While the term consequentialist bracketing was first used by DiGiovanni (2025b)[3], the idea was formalized by Kollin et al. (2025). It basically aims at providing a principled way of excluding some paralyzing considerations from our decision-making (i.e., "bracketing them out") to find action-guidance, butguidance. Still, it comes with (at least) the following potential problems:
DiGiovanni offers a comprehensive list of potential objections to his argument, and their rebuttals, but he mentions two attempts to find action-guidance despite cluelessness: i) consequentialist bracketing, and ii) a metaepistemic wager. Both are discussed below, right after we get more precise on DiGiovanni's empirical premise.

The Cross-Cause Fund (CCF) is an expert-managed cause-neutral fund. It is run by Rethink Priorities' cross-cause fund team, which is composed of members of its Leadership and Executive Team, Worldview Investigation Team, and Interdisciplinary Research Team.
It was launched in May 2026 as a fund explicitly aimed at full impartiality across(across all cause areas.areas)[1] — at a time when, per RP's own analysis, only 2% of EA prioritization resources were allocated to cross-cause prioritization, an area RP describes as historically underdeveloped in effective giving.
This sentence from the CCF website offers a good summary of the goal and intent:
With two caveats. First, RP cannot consider political candidates as potential beneficiaries of donations. Second, as of August 2026, multiple worthy causes have not yet been included in the evaluation, e.g., meta work (though the causes that have been included were prioritized intentionally, given specific cross-cause prioritization assumptions)assumptions plus lack of time to get closer to an ideal allocation). See the CCF FAQ for more related information.

I've now brought back and lightly edited this paragraph that gives a helpful example. I think all the rest had low relevance, was misleading, or outright false.
Many objections/reactions to DiGiovanni's argument would be worth discussing, but I'm worried about transforming this tag page into a long paper. So a lot of work is done by:
