The Preheating Effect: How Being in a Good Mood Makes You More Likely to Give to Charity

Two economists published a new study in The Economic Journal that found when people feel happier, they're more likely to donate to charity. We analyzed over 20,000 Twitter users' tweets using natural language processing tools to assess sentiment levels before and after donating. We found donors had an especially upbeat mood prior to donating, and then their sentiment quickly returned to their baseline. Our findings suggest that feeling good may make people more likely to give to charity, which contradicts the theory that people give to charity because it makes them feel good.

The big idea .

When people feel happier, they’re more likely to donate to charity. That’s what we, two economists who study what motivatesenvironmentally conscientious consumption and support for free services, found in a new study published in The Economic Journal.

To conduct this research, we analyzed tweets from over 20,000 Twitter users who used the hashtag "#iloveWikipedia." That slogan is part of a template that Wikipedia suggests to anyone who has just completed a donation on its online platform, so it helped us identify people who have given money to the free online encyclopedia edited by volunteers. Those donations funded the Wikimedia Foundation, the nonprofit that hosts Wikipedia.

Our study analyzed tweets from over 20,000 Twitter users.

We evaluated the donors’ moods by using natural language processing tools. These tools assigned a score to each tweet to indicate how positive or negative the mood was for each tweet.

For example, a tweet that says "Woohoo! Awesome Pete!" would get a positive sentiment score, while one that says "THIS MADE ME CRY OUT OF ANGER AND SADNESS AND FRUSTRATION." would get a negative one. We used four different scoring systems, all of which allowed us to gauge how strongly positive or negative a Twitter user’s mood was. We could adjust these sentiment scores by comparing them to a user’s other tweets.

We used four different scoring systems to gauge sentiment.

We found that donors’ sentiments became more upbeat up to an hour before they made a gift to support Wikipedia and then declined, becoming more neutral pretty quickly after that. Donors tended to be in especially good moods before making their gifts, but they regressed quickly to their more typical mood afterward.

We can’t be sure why people were feeling happier before they donated than they did afterward, but our findings suggest that feeling good could make you more likely to give to charity. We call this the "preheating effect." Our observation about donor behavior contrasts with an economic theory that people may give to charity because it makes them feel good about doing the right thing. This feeling is known as a "warm glow." .

Previous studies have tried using both happy and sad moods to study philanthropy.

Why it matters .

Scholars of philanthropy have long known that giving to charity is tied to happiness. What’s less clear is whether being charitable makes people happier, or whether happier people are more charitable. Our study offers new evidence that feeling happy before they’re asked to make a donation makes people more likely to give.

Previous studies have sought to make research participants feel happy or sad and then analyzed how those moods may affect their inclination to behave in helpful ways. However, we were able to capture the donors’ real-world moods, which is more relevant to fundraising in terms of determining what might make someone more likely to make a charitable donation.

We can't say definitively that being in a good mood directly causes people to give.

What still isn’t known .

Based on the evidence we scraped from tweets, it’s not possible to tell whether being in a good mood makes people more likely to give to charity, or if feeling happy simply makes donors more likely to tweet about their gifts.

Also, our study looked at the apparent emotional state of Twitter users, and not everyone actively uses that social media platform. Because of that limitation, we can’t draw any definitive conclusions about the motivations of donors more generally.

The average increase in sentiment prior to donation was not statistically significant.
