The science of rat empathy and what it tells us about human kindness

Rats: more human than you think.DISCLOSURE: No rats were hurt in the making of this amazing bit of empathy science. And humans can actually learn from their example.

The science of rat empathy and what it tells us about human kindness

Most people aren't super into rats.

Otherwise known as Tuesday in New York City.


It's hard to blame them. Between the black plague, killing roughly 10 million people in the last century alone, and nearly ruining the careers of underpaid French cooks, rats haven't exactly gone out of their way to endear themselves to humans over the last several thousand years.

Bottom line: Rats don't give a rat's ass about humans.

But as Discovery magazine reported, there is one thing rats do seem to really care about: each other.

Some scientists ran an experiment to demonstrate that. Here's how it worked:

  1. The scientists put a rat in water (which rats hate). Not enough to hurt the rat, but enough to annoy it.
  2. Then they put another rat in a safer, dry area with a door it could open to save the first rat.

To make things more fun, I'm naming these rats Tippy and Tina. Rat images via Thinkstock.

When the dry rat heard the damp, miserable rat get upset, she came to the rescue.

You can watch the video of it here:

Still not satisfied with the result, the scientists ran a more complex test.

What if you bribe the dry rat with food? Will she ignore it to rescue the wet rat in the next chamber?

Scientists presumed it would be easier for the not-in-peril rat to take the obvious selfless route when it was given only one choice. But what if they gave her a delicious bribe (chocolate cereal) and then let her choose between saving her friend and a buffet?

Tina can go right and get delicious cereal or she can go left and rescue Tippy.

The rats, by a significant margin, still usually saved their friend before getting their delicious bribe.

What does that mean?

Rats might care more about each other than things like food, and that prioritization might be encoded in their DNA.

Why should we care about super-thoughtful rats?

It is often argued that humans are inherently selfish — that without guidance, we would all default to killing and stealing and an "every person for themselves" mentality. That we only help others if it helps us. That evolution can't make us selfless; it's something we have to force ourselves to do.

But if rats show human-like qualities (they laugh like us, they dream like us, they like to have selfless lovers) like altruism, that means it isn't a human-learned behavior.

It could be encoded in our DNA. It means humans could be empathetic and kind by default.

It also means that rats and humans have more in common than we think.

An adorable rat not spreading the plague and hugging a tiny teddy bear. Much empathy.

Mind. Blown. Adorably.

Even as millions of Americans celebrated the inauguration of President Joe Biden this week, the nation also mourned the fact that, for the first time in modern history, the United States did not have a peaceful transition of power.

With the violent attack on the U.S. Capitol on January 6, when pro-Trump insurrectionists attempted to stop the constitutional process of counting electoral votes and where terrorists threatened to kill lawmakers and the vice president for not keeping Trump in power, our long and proud tradition was broken. And although presidential power was ultimately transferred without incident on January 20, the presence of 20,000 National Guard troops around the Capitol reminded us of the threat that still lingers.

First Lady Jill Biden showed up today with cookies in hand for a group of National Guard troops at the Capitol to thank them for keeping her family safe. The homemade chocolate chip cookies were a small token of appreciation, but one that came from the heart of a mother whose son had served as well.

If the past year has taught us nothing else, it's that sending love out into the world through selfless acts of kindness can have a positive ripple effect on people and communities. People all over the United States seemed to have gotten the message — 71% of those surveyed by the World Giving Index helped a stranger in need in 2020. A nonprofit survey found 90% helped others by running errands, calling, texting and sending care packages. Many people needed a boost last year in one way or another and obliging good neighbors heeded the call over and over again — and continue to make a positive impact through their actions in this new year.

Upworthy and P&G Good Everyday wanted to help keep kindness going strong, so they partnered up to create the Lead with Love Fund. The fund awards do-gooders in communities around the country with grants to help them continue on with their unique missions. Hundreds of nominations came pouring in and five winners were selected based on three criteria: the impact of action, uniqueness, and "Upworthy-ness" of their story.

Here's a look at the five winners:

Edith Ornelas, co-creator of Mariposas Collective in Memphis, Tenn.

Edith Ornelas has a deep-rooted connection to the asylum-seeking immigrant families she brings food and supplies to families in Memphis, Tenn. She was born in Jalisco, Mexico, and immigrated to the United States when she was 7 years old with her parents and sister. Edith grew up in Chicago, then moved to Memphis in 2016, where she quickly realized how few community programs existed for immigrants. Two years later, she helped create Mariposas Collective, which initially aimed to help families who had just been released from detention centers and were seeking asylum. The collective started out small but has since grown to approximately 400 volunteers.
