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.

This report explains the common mistakes we make when predicting the intensity and duration of our own and others’ feelings and the implications this has for global priorities research.

Drawing on evidence from over 80 studies and over 140,000 participants, we compare the cost-effectiveness of cash transfers and psychotherapy by estimating their effect on the recipient's subjective wellbeing and affective mental health.
This report explains how we determined the cost-effectiveness of cash transfers using subjective wellbeing and affective mental health.
This report explains how we determined the cost-effectiveness of group or task-shifted psychotherapy in low- and middle-income countries using subjective wellbeing and affective mental health.
This report explains how we determined the cost-effectiveness of StrongMinds using subjective wellbeing and affective mental health.
The Mental Health Programme Evaluation Project (MHPEP) was an HLI-led volunteer project that ran from February 2019 to October 2021.The principal aim of the project was to identify and direct donations to highly impactful mental health programmes.
This report investigates the global burden of mental illness. It sets out how big the problem is, how much spending it receives, and how those resources are allocated. It then focuses specifically on what can be done to reduce anxiety and depression in low-income countries.
We know cash transfers reduce poverty, improve health and enhance education but what impact do they have on how people feel and think about their lives? We find that cash transfers have a small, positive effect on subjective wellbeing, one that lasts for several years.
There are long-standing doubts about whether data from subjective scales are cardinally comparable—should we, for instance, believe that if two people self-report their happiness as '7/10' then they are as happy as each other? It is unclear how to assess whether these doubts are justified without first addressing two unresolved theoretical questions: how do people interpret subjective scales, and which assumptions are required for cardinal comparability? This working paper offers answers to both.

Millions suffer excruciating pain. Millions more suffer moderate or severe pain. They suffer despite the fact that cheap and effective treatments exist. This report briefly discusses the measurement of pain then explores three major causes of pain and what might be done to relieve them.
This short article summarises what philosophers do (and don't) mean by the term "wellbeing". It introduces the three main rival accounts of what wellbeing is and considers their theoretical strengths and weaknesses.
We show how Wellbeing-Adjusted Life Years (WELLBYs) can be used to estimate the value of different outcomes. We then estimate the values of two key inputs in GiveWell’s analysis: doubling consumption for one person for one year and averting the death of a child under 5 years old.
This working paper makes three main claims: 1) life satisfaction theories are indistinguishable from global desire theories; 2) these theories are the only subjectivist accounts of wellbeing; and 3) subjectivism is implausible, although for different reasons from those that are usually given.

In his DPhil thesis, Michael Plant critiques and develops claims about how individuals can do the most good including discussion of the value of saving lives, how best to improve lives, and cause prioritisation methodology.
