The story behind the internet’s most viral (and misunderstood) political meme

A study on the “moral circles” of liberals and conservatives gets drafted into the culture wars — with mixed results.

Key Takeaways
  • Liberals care more about aliens and amoebae than they do about actual people.
  • So says a pair of “moral circle” heatmaps, which have been weaponized into a popular meme after appearing in a 2019 study.
  • The meme has been used as ammo in the culture wars, but the truth is a bit more complex.

“The quality of mercy is not strained,” argues Portia in The Merchant of Venice, meaning there should be no limits to being kind and forgiving. But 21st-century culture wars are no Shakespeare play. These days, mercy is a finite resource, and the question is how strained the quality (and quantity) of yours is, for it might reveal your tribal affiliation: liberal or conservative.

Opposite moral universes

At issue is a set of heatmaps from a scientific article exploring the “moral circles” of liberals and conservatives.

A moral circle is a concept in philosophy and the social sciences that represents the groups of people and entities one considers worthy of moral concern.

In the images below, categories like “immediate family” and “closest friends” appear in the innermost rings, while broader categories like “all mammals” and “all things in existence” are placed in the outermost rings, reflecting an expanding scope of moral inclusion. The participants in the study indicated the size of their moral circle by clicking the rung to which theirs extends.

Two heat maps side by side depict density plots. The left is labeled "Conservatives" and the right "Liberals," with a color scale from blue (low) to red (high) density.

At first glance, the maps suggest that both ideological tribes inhabit moral universes that aren’t merely different — they’re almost entirely opposite.

Conservatives seem to focus their moral concern on the smaller moral circles, concentrating the most care on family while also extending some outward toward categories like their country. Meanwhile, liberals seem to care more about the more universal and “distant” categories, including rocks, aliens, and amoebae. Their liberal hearts bleed for people and causes far away — all while ignoring the needs of those who are much nearer, and therefore should be much dearer, to them (or at least that’s how the meme is commonly framed online).

In recent weeks, the maps turned into live ammunition in the ideological firefight over the shutdown of USAID. After all, they seem to perfectly illustrate a conservative point: Liberals (and liberal-inspired institutions like the U.S. Agency for International Development) expend Americans’ limited reserves of care and compassion abroad, neglecting needs at home.

Why should U.S. taxpayers fund lesbian street theater in Tbilisi when fellow Americans are going hungry in their own country? Why indeed listen at all to arguments coming from a side of the political spectrum that has its moral priorities so completely, perversely wrong?

The heatmaps might seem to offer scientific proof for what millions of conservatives already thought, summarized by one poster on X as: “Liberals are mentally ill!”

This, however, is a rather partisan reading of the data, which was first presented in an article in Nature in 2019 before being weaponized into a meme that has been misinterpreted by countless people on social media.

The main misinterpretation: The heatmaps do not convey that liberals or conservatives “care more” about any particular category within the moral circle (though data from other studies in the paper do speak to differences in so-called “moral allocation” — more on that in a moment).

Stupid, middlebrow, and supersmart

Arguably the most potent version of that meme merges the heatmaps with a multipurpose version of the IQ bell curve, populated with three “wojaks” on the stupid, middlebrow, and supersmart bits of that curve.

The liberal heatmap is paired with the figure in the meaty middle of the graph, while the conservative one fits with the narrower extremes of the IQ spectrum. The message here: Caring for things far away rather than those close by is typical for “midwits” — people too smart to be really stupid, but also too stupid to be really smart.

Focusing your care and attention on people in one’s immediate surroundings is not just something the very stupid do, but paradoxically it’s also how the very clever roll. (No prizes for guessing which part of the curve the re-posters of this meme identify with.)

“Catnip for conservatives”

It’s hard to argue with something as convincing as a pair of blurry color gradients stuck onto a trio of badly drawn faces, but some have tried nonetheless.

“This graphic is rapidly becoming the most misused and misunderstood image in all of modern history,” hyperbolized podcast host Liv Boeree. “Despite what its spreaders claim, it doesn’t show that liberals care ‘less’ about those close to them (…) It simply shows that they tend to ‘also’ care about further away things as well.”

Referring to the original study, she says the heatmaps “show only the distribution of EDGES of the two groups’ moral circles, NOT the distribution of their FOCUS. And frankly, anyone with an iota of reason could figure that out if they actually sat down and thought about it… There’s basically no one on earth who truly cares about a total stranger or rock or insect MORE than their friends, which is what this chart would imply if interpreted this way.”

“Not even crazy ass wokies have such an inverted moral circle,” she goes on, concluding the heatmaps went viral simply because they feed one tribe’s confirmation bias: “(This is) catnip for conservatives”.

Boeree is at least correct about one common misunderstanding about the heatmaps: The heatmaps visualize only the size of liberals’ and conservatives’ moral circles — not how they chose to allocate moral concern. (In defense of the misunderstanders, the descriptions of the tasks and figures in the Nature paper are not exactly easy to follow.)

The task that generated the heatmaps told participants that all concentric circles were inclusive of the preceding ones, such that “if you select 10 (all mammals), you are also including numbers 1-9 (up to ‘all people on all continents’) in your moral circle.”

So, the heatmaps alone do not show that conservatives or liberals necessarily “care more” about any particular group.

Elsewhere in the paper, however, some key differences between liberals and conservatives do emerge.

Allocating “moral currency”

The Nature paper included multiple tasks in which participants were asked to engage with moral circles. The task that generated the heatmaps was inclusive: If participants indicated that their moral circle included “plants and trees,” that did not mean they necessarily cared any less about, say, their family.

But other tasks were not inclusive. Study 3a included a survey of 130 U.S. residents (64 liberals, 36 conservatives, 31 moderates), each of whom was given 100 “moral units.” Participants were asked to distribute these units (think of them as “moral currency”) according to their capacity to empathize with and behave morally toward the categories featured in 16 concentric circles, from close to increasingly distant:

(1) all of your immediate family, (2) all of your extended family, (3) all of your closest friends, (4) all of your friends (including distant ones), (5) all of your acquaintances, (6) all people you have ever met, (7) all people in your country, (8) all people on your continent, and (9) all people on all continents.

Those first nine categories only concern people — the next six only deal with nonhuman entities; animals and inanimate objects:

(10) all mammals, (11) all amphibians, reptiles, mammals, fish, and birds, (12) all animals on earth including paramecia and amoebae, (13) all animals in the universe, including alien lifeforms, (14) all living things in the universe including plants and trees, (15) all natural things in the universe including inert entities such as rocks, and (16) all things in existence.

The participants were instructed that these categories were “non-overlapping, such that giving to one category (e.g., extended family) would not include an inclusive category (e.g., immediate family),” meaning this allocation task differed from the task that generated the heatmaps because it was exclusive.

So, how did conservatives and liberals allocate their limited supply of moral currency?

Exclusive circles

Conservatives tended to prioritize the nine inner circles (human entities), while liberals distributed relatively more on the outer circles (nonhuman).

But does that study capture how morality works in real life? In other words, do we really have a finite supply of moral concern to dole out, such that being morally concerned about plants and trees means we necessarily have less concern to “spend” on categories like our families?

The authors acknowledged this question by noting that study 3a imposes an “artificial constraint” on moral concern, considering that participants were given no more than 100 moral units to dispense — restricting the quantity of their mercy, so to speak.

“(This forced) participants to distribute moral concern in a zero-sum fashion (i.e., the more concern they allocate to one circle, the less they can allocate to another circle),” the researchers noted. “Although research suggests that people indeed do distribute empathy and moral concern in a zero-sum fashion, this feature of Study 3a imposes an artificial constraint.”

Study 3b did not impose a limit on the moral units participants were allowed to allocate. While it shows a similar pattern, the division between both ideologies is more diffuse than in study 3a. .

Hence study 3b, which examined the moral leanings of another group of respondents, this time without a limit on the moral units they were allowed to allocate. As the lines show, a similar pattern does emerge, with liberals expending moral concern mainly toward bigger circles (“nonhumans”), while conservatives do so toward the smaller ones (“humans”).

But as the distribution of blue (liberal) and red (conservative) dots illustrates, the division is rather more diffuse and less stark than in study 3a.

(Quick aside on how liberals and conservatives expended moral concern within the “human” category: It’s worth noting that Study 1a found that “very liberal” participants reported stronger feelings of love toward their friends compared to “very conservative” participants, while conservatives expressed greater love for their family. However, the researchers cautioned that these correlations were very small and should be interpreted with caution.)

Universalism vs. parochialism

Altogether, the results of the paper’s seven studies all point in the same direction: Conservatives tend to prefer smaller moral circles (parochialism) and liberals generally prefer bigger ones (universalism).

“This difference manifested in conservatives exhibiting greater concern and preference for family relative to friends, the nation relative to the world, tight relative to loose perceptual structures devoid of social content, and humans relative to nonhumans,” the authors noted.

So, to get down to brass tacks: Are the weaponizers of this meme correct? While countless people on social media have misinterpreted what the heatmaps actually convey, conservatives would be generally correct to note that the studies in the Nature paper do suggest that liberals have larger moral circles and tend to distribute moral concern more universally than conservatives — at least in the context of these studies.

But any suggestion that moral concern should always be rigidly reserved for our closest circles is subjective and debatable, to say the least. Hence this point from psychiatrist and rationalist blogger Scott Alexander:

“I went on a walk and saw a child drowning in the river. I was going to jump in and save him, when someone reminded me that I should care about family members more than strangers. So I continued on my way and let him drown.”

As time goes on, it is probably the meme (rather than the minutia of the study) that will survive — perhaps in this, one of its more amusing manifestations: a steak and an avocado laid out on two plates, in the shape of the liberal and conservative moral circles.

Naturally, the steak refers to the conservative heatmap, and the avocado to the liberal one. Heavily implied: The steak eater cares for family, friends, and other Americans. The avocado muncher, though, hates all people in those categories, and will not rest until Tbilisi is flooded with lesbian street theater.

Editor’s note: This article was updated at 11:43 a.m. E.T. on March 4, 2025, to clarify the differences between the “exclusive” moral concern allocation tasks and the “inclusive” task that asked participants to indicate the size of their moral circles.
