The Gratitude Experiments:
Why naysayers are dead wrong about the power of thanking
An exclusive, live-annotated excerpt from Thankology... by me, author and fundraising copywriter Lisa Sargent and your friendly Loyalty Letter publisher ✍️

In June 2018, then University of Chicago researchers Amit Kumar and Nicholas Epley conducted three experiments during which they asked participants to write gratitude letters (live-annotation from me: thank you letters), then predict how their letters would make the intended recipients
feel.
What they discovered was remarkable indeed:
1. Senders overestimated how awkward they would make the recipients feel.
2. Senders underestimated how much the letter of gratitude would mean to recipients.
Live-annotation from me: what does this mean to you, Loyalty Letter subscribers? When you’re trying to build your case for better
thanking, and someone tries to wave your work away with, “It’s just a thank-you letter”... you can now prove differently.
The key element for recipients?
Warmth of the letter.
(Live annotation from me: dry-as-dust form thank-yous need not apply.)
The results led the researchers to a conclusion they summed up so beautifully, I include it verbatim
here:
“Expressing gratitude is a powerful act of civility benefitting
both expressers and recipients.”
— Amit Kumar and Nicholas Epley
Kumar and Epley aren’t the only researchers to show the notable effects of properly expressing thanks.
In two gratitude experiments, conducted by Francesca Gino, now a professor at Harvard Business School, and Wharton School’s Adam Grant, a simple thank‑you letter heightened
the recipients’ sense of self-worth. (See The Harvard Gazette and "A Little Thanks Goes A Long Way")
By more than double.
And Gino and Grant’s study suggests that the effects of not saying thank you are closely linked to a person’s willingness to offer future support.
How much more willing?
You guessed it: More than double.
Gino even went so far as to say that the extent of what she came to call “the Gratitude Effect” was the
most surprising part of her research.
Live-annotation from me: So what happens when naysayers tell you that you don’t really even need to thank donors at all? Well, you can set them straight...
When it comes to not thanking donors, Dr. Adrian Sargeant’s timeless research report, "Managing Donor Defection: Why
Should Donors Stop Giving?", exposes similar trouble.
His work showed that when donors were asked their reasons for no longer supporting an organization, 13.2% came right out and said it was because they hadn’t been thanked.
Dive deeper into Professor Sargeant’s findings, and you’ll see more trouble:
- 36.2% said they felt other causes were more
deserving
- 9.2% couldn’t recall supporting the organization
- 8.1% said they hadn’t been informed how their donations were used
- 5.6% said the organization no longer needed their support.
It’s not a big jump to see that in addition to the 13.2% who specifically said they left because they were never thanked, the other reasons I’ve just listed above are at least in some way tied to
a lack of proper acknowledgment.
