🎉 Giving Multiplier turns 5!

We launched in 2020 as a proof of concept — could we apply behavioral science to help people increase their charitable impact?

“We would have been happy if we raised a little bit
better than bake sale," said co-founder Prof. Joshua Greene.

Today is #WorldFarmAnimalsDay. We've partnered with FarmKind to help free an estimated 100,000 hens from cages by supporting The Humane League (@thehumaneleagueus.bsky.social).

We're adding 50% in matching funds!

A hen spends her life in a cage no bigger than an iPad, unable to spread her wings.

This #WorldFarmAnimalsDay, let's change that. For less than a dollar, you can help free a hen, and your donation gets a 50% boost all week long. With your help, we can free 100,000 hens.

New article I wrote at Behavioral Scientist (@behscientist.bsky.social): I share the psychological research on "drop-in-the-bucket" thinking, how this tendency shows up when trying to make an impact, and what we can do about it.

How ‘Proportion Dominance’ Gets in the Way of Effective Giving - by Matthew Coleman - Behavioral Scientist
When it comes to helping others, it’s important to remember that it’s the size of the drop that matters, not the size of the bucket.

ICYMI: Three weeks ago, we were featured on the "Trolleyology" episode of @ologies.bsky.social.

Since then, hundreds of Ologites have collectively directed an astounding $445,000 toward combating extreme poverty and climate change, supporting 230+ of their favorite nonprofits, and much more. Bravo!

♻️ Giving Multiplier powers a virtuous circle of giving.

Matching funds inspire donations to highly effective charities. In turn, those donations encourage others to provide more matching funds.

This "supply-and-demand" cycle creates impact today, while sustaining our platform for the future.

For @nytimes.com, @nickkristof.bsky.social writes that global hunger is one problem we can address. 🌍

“We have a whole set of solutions,” says Helen Keller Intl's Shawn Baker in the piece. 🍠

But without US funding, many of these solutions are no longer reaching the people who need them most. 🍽️

Really cool new preprint: charity effectiveness information can boost donations. But framing matters.

When cost-effectiveness falls below expectations, it can backfire and actually reduce giving.
