I would find this argument much more convincing if it were supported by people who actually have children. My mother goes beserk over a smiling infant in a way I cannot begin to comprehend (I am usually afraid I will accidentally hurt them). My husband, likewise, has an instant affinity for babies and always tries to communicate and play with them. He was raised Jewish with the idea that it is unclean to have animals in the home and does not find animals particularly adorable. In our culture we are inundated with anthropomorphised images of animals in television and given stuffed toys and pets that we take care of like children. It's not that surprising that we find animals cute when we focus so much attention on them as if they were little people. I do not know that such evaluations of 'cuteness' would hold cross-culturally, especially in cultures where people do kill and eat 'cute' animals on a regular basis.

"Drastically misaimed" really says nothing about whether or not a cuteness instinct would be a good adaptation, though. A counterexample: it's a fact that our visual systems are acutely sensitive to rapidly-moving things. The evo-bio hypothesis is that this is predator detection. Does the fact that 99.999999% of the rapidly-moving things I notice aren't predators negate this hypothesis as well?

I can't think of very many cases in which people endanger themselves or their reproductive chances for the sake of cute animals. I'm sure it's happened once or twice, but using this argument means demonstrating that the number of potential children lost due to finding bunnies cute is greater than the number of actual children attended to due to finding them cute.

As an aside, I think that Google in this case is adding to the confusion. The evo-bio cuteness theory is generally stated as being about a system that detects facial markers that strongly differentiate babies from adults - the key ones being eyes large relative to head size, pursed mouths, round cheeks, and round chins. Some baby animals, when viewed up close in Google, display some of these characteristics. In the wild, however, baby animals are almost never seen up close, and even when they are, they trigger the facial recognition systems only in dribs and drabs, like bad CG.

I agree that evolutionary psychology is very prone to abuse and should probably usually be avoided, but this seems like a terrible example to me. The hypothesis that cuteness is our evolved response to baby-like features does NOT predict that babies will be the cutest thing.

How come everyone is missing the obvious answer? The human ancestor that first developed attachment to babies may be an ancestor we share with rabbits.

(Edit, Also: Human babies may have evolved to be uglier for other reasons -less hair, bigger heads- and those features may have been selected for more than cuteness.)

Edit 2: Metaphorically, our cuteness program is like running Netscape Navigator 1.0 or something. It sort of does the trick but isn't exactly adapted for modern uses

Don't any of you have children?? Newborn babies are one thing, but there's a cuteness of seeing small, perfect little versions of yourself or your mate... I don't think a bunny could really compete.

No, other people's babies aren't that cute, but mine sure as hell are.

And in any case, I don't really see how this relates to... whatever it is you are saying about ev-psych (or the deeper mystery of cuteness). Why would you expect evolution to make us only find human babies cute? Evolution only has to work hard enough to keep us from abandoning our babies, and to hell with the (bunny-related) side-effects. Why would evolution care how cute you think bunnies are, as long as it's not so much that you start eating your babies and raising rabbits?

I wanted to say this for a long time: human babies aren't cute. Certainly not newborns. If I didn't know better, and saw a newborn, I would perform an exorcism. They look like creatures from the Uncanny Valley.

Edit: Seventeen points? Maybe I should make this a top-level post. Opinions?

First I lose about that many from a very thoughtful post because of my unusual sense of humor. Then I gain them back on... this? People, start making sense.

If anyone is curious about my stance on this now that I have reproduced:

• My baby is cuter than most babies. Some people who are not related to him have agreed with me on this but there is probably still bias in the sample. He does have traits I have always considered advantageous in babies generally or desirable in mine specifically though.

• He is very difficult to photograph well. He gets distracted by the camera and moves at inopportune times. Wildlife photographers probably have solutions to similar wildlife-related issues and maybe pro baby photographers do too. I don't know how this affects image quality ratios in Google results.

• My baby is much more appealing as a process than a snapshot. He is soft and squishy and warm in addition to being nice to stare at, and has learned to smile and laugh in response to things we do, and he is endearingly incompetent at many tasks he attempts. Some animals can do that sort of thing too though.

I still think it's suspect that the cuteness response fires strongly in response to bunnies etc., but I may have stacked the deck more than I would have if I had known more at the time.

Maybe the bunny has evolutionarily converged on the mammal shared cuteness pattern, but the baby has been forced to diverge by other pressures? Human babies are born very underdeveloped relative to other species. I've read speculation that this is due to the upright walking, hip shape, head size, brain size compromise, and that seems sensible to me. Cuteness optimization may have been shoved aside as lower priority.

A cognitive module for cuteness only needs to make us find babies a nice thing and enhance the probability of parental care. It simply doesn’t matter if, besides doing that, the same cognitive module make us find bunnies or orthorhombic sulfur crystals at low temperature cute, so long this doesn’t have any deleterious effects. Probably a cognitive module that can find cute only human babies and not bunnies is more evolutionary improbable and developmental costly having the same relevant behavioral results of a more cheap and universal cognitive module for cuteness. Evolution only needs to shape cognition in order to generate, more or less, the right type of behavior. It DOESN’T have to, and in most cases it doesn’t, shape cognition nicely, in a way we would look at it and say “nice work”.

It seems very oversimplified to say, "We think babies are cute because we have to." "Cuteness" casts a pretty wide net when you start thinking of all the things we say are "cute." A sample list of things I've heard described as cute:

• Babies
• Bunnies
• Targets of sexual attraction
• Small consumer goods, such as tiny containers of shampoo, small forks, etc.
• Some old men
• Targets of sarcastic comments ("That's real cute, but .. ")

It seems like we reserve the word for "things that are vulnerable/harmless/ineffective and don't realize it, which then triggers an urge to keep the thing's inaccurate self-perceptions about its own effectiveness intact."

Actually, I find the baby about 75 000 cuter. This might have something to do with the fact that I'm a) a girl, and b) right at the age when, biologically speaking, I should be having kids. I see babies in the street and get warm fuzzy feelings. My (female) friends and I at work talk about how much we want to take home every baby in the Parent & Tot swimming classes. We show each other pictures of friends' babies and go completely gaga. Just wanted to point out that this may be something that varies with sex. (Although not for everyone, of course.)

This study suggests looking at kitten pictures makes you more careful, improving performance in fine-motor dexterity tasks such as mock surgery.

I wonder if this could lower the error rate of computer programmers, and whether I should buy Eliezer a kitten.

We find bunnies in general cute, but not humans in general -- so it makes sense that a baby bunny would be cuter than a baby human. It combines babyness and bunnyness, as compared to a human baby who only has babyness. We care about the human baby more than the bunny baby because we value humanness quite apart from cuteness.

Perhaps the cuteness response is tied to domestication - ie, evolution wants us to take the bunny with us until it gets old enough to stop being cute, and then eat it.
