Happiness as a measure of success

Everyone agrees that happiness is important. However, the world still tends to measure success in terms of wealth or physical health – completely ignoring happiness…

… But it doesn’t have to be that way. We can measure people’s happiness using a metric called a WELLBY. 

Times are changing. Even the UK Treasury is starting to measure happiness using WELLBYs. 

Proven to maximise happiness

We’ve done over 40,000 hours of research to find which charities create the most happiness in the world. 

Our research shows some charities are at least 5 times more cost-effective than the leading benchmark.  

Other charities we’ve assessed could be 50–100x more cost-effective

I've been very impressed with the quality of HLI's work. They help represent more diverse views, raise the standards for us all, and this greatly improves the effective giving ecosystem.
