Are we living at the hinge of history?

GPI Working Paper No. 12-2020, published in Ethics and Existence: The Legacy of Derek Parfit
In the final pages of On What Matters, Volume II, Derek Parfit comments: ‘We live during the hinge of history... If we act wisely in the next few centuries, humanity will survive its most dangerous and decisive period... What now matters most is that we avoid ending human history.’ This passage echoes Parfit's comment, in Reasons and Persons, that ‘the next few centuries will be the most important in human history’.
But is the claim that we live at the hinge of history true? The argument of this paper is that it is not. The paper first suggests a way of making the hinge of history claim precise and action-relevant in the context of the question of whether altruists should try to do good now, or invest their resources in order to have more of an impact later on. Given this understanding, there are two worldviews - the Time of Perils and Value Lock-in views - on which we are indeed living during, or about to enter, the hinge of history.
This paper then presents two arguments against the hinge of history claim: first, that it is a priori extremely unlikely to be true, and that the evidence in its favour is not strong enough to overcome this a priori unlikelihood; second, an inductive argument that our ability to influence events has been increasing over time, and we should expect that trend to continue into the future. The paper concludes by considering two additional arguments in favour of the claim, and suggests that though they have some merit, they are not sufficient for us to think that the present time is the most important time in the history of civilisation.

Tough enough? Robust satisficing as a decision norm for long-term policy analysis – Andreas Mogensen and David Thorstad (Global Priorities Institute, Oxford University)
This paper aims to open a dialogue between philosophers working in decision theory and operations researchers and engineers whose research addresses the topic of decision making under deep uncertainty. Specifically, we assess the recommendation to follow a norm of robust satisficing when making decisions under deep uncertainty in the context of decision analyses that rely on the tools of Robust Decision Making developed by Robert Lempert and colleagues at RAND …
Calibration dilemmas in the ethics of distribution – Jacob M. Nebel (University of Southern California) and H. Orri Stefánsson (Stockholm University and Swedish Collegium for Advanced Study)
This paper presents a new kind of problem in the ethics of distribution. The problem takes the form of several “calibration dilemmas,” in which intuitively reasonable aversion to small-stakes inequalities requires leading theories of distribution to recommend intuitively unreasonable aversion to large-stakes inequalities—e.g., inequalities in which half the population would gain an arbitrarily large quantity of well-being or resources…
Quadratic Funding with Incomplete Information – Luis M. V. Freitas (Global Priorities Institute, University of Oxford) and Wilfredo L. Maldonado (University of Sao Paulo)
Quadratic funding is a public good provision mechanism that satisfies desirable theoretical properties, such as efficiency under complete information, and has been gaining popularity in practical applications. We evaluate this mechanism in a setting of incomplete information regarding individual preferences, and show that this result only holds under knife-edge conditions. We also estimate the inefficiency of the mechanism in a variety of settings and show, in particular, that inefficiency increases…
