A can of worms: the non-significant effect of deworming on happiness

In this report, we summarise the debate about the efficacy of deworming, present the first analysis of deworming in terms of subjective wellbeing, and compare the cost-effectiveness of deworming to StrongMinds (our current top recommended charity).

The elephant in the bednet: the importance of philosophy when choosing between extending and improving lives

How should we compare the value of extending lives to improving lives? Doing so requires us to make various philosophical assumptions, either implicitly or explicitly. But these choices are rarely acknowledged or discussed by decision-makers, all of them are controversial, and they have significant implications for how resources should be distributed.

Deworming and decay: replicating GiveWell’s cost-effectiveness analysis

We make four recommendations to improve GiveWell’s cost-effectiveness analyses: (1) publicly explain and defend their assumptions about the effect of deworming over time; (2) explain their cost-effectiveness analyses in writing; (3) illustrate the sensitivity of their results to key parameters; (4) make it clear when an estimate is subjective or evidence-based.

A philosophical review of Open Philanthropy’s Cause Prioritisation Framework

On this account, the appropriate decision under moral uncertainty is the one that would be reached as the result of negotiations between agents representing the interests of each moral theory, who are awarded resources in proportion to your credence in that theory.

Will faster economic growth make us happier? The relevance of the Easterlin Paradox to Progress Studies

Progress Studies has been popularised by academics such as Tyler Cowen and Steven Pinker. However, the Easterlin Paradox presents a real challenge to the claim that if we want more progress, we just need to improve the long-run growth rate - a view that Cowen argues for in his book Stubborn Attachments.

Happiness for the whole family

We update our previous analysis to incorporate the household spillover effects for cash transfers and psychotherapy. We estimate that psychotherapy is 9 times (95% CI: 2, 100) more cost-effective than cash transfers. The charity StrongMinds is estimated to be 9 times (95% CI: 1, 90) more cost-effective than the charity GiveDirectly.

Global priority: mental health
