Babies are more curious than afraid when it comes to snakes.
As someone who's been afraid of snakes for as long as I can remember, I've often wondered where that fear came from. I've never been bitten or harmed by a snake. I've had close encounters with rattlesnakes out in the wild, but no actual strikes. I've had friends with pet snakes that were perfectly docile, and I've even held and petted snakes before (with no small amount of trepidation). While I think a healthy respect for snakes is wise, as some can be dangerous or even deadly, my fear goes way beyond that. I know lions, tigers, and bears are dangerous as well, but don't feel like I'm going to jump out of my skin when I see them like I do when I see a snake.
Why, though? Is that reaction something I learned when I was little, or is it an instinctive, evolutionary fear I inherited from my ancestors?

Theoretically, the question of whether fears are innate or learned can at least somewhat be answered by seeing how babies react to things. Every baby is different, of course, and some are more sensitive to certain things than others, but researchers have found that babies in general do not exhibit a natural fear of snakes. In their infancy, children largely learn what to fear by observing the reactions of the people around them, whether their parents or others have a negative or positive reaction to something. A fear of snakes might develop early on if a caregiver demonstrate that fear themselves. But without observing that, if you put babies in a room with snakes, they won't be afraid.
And yes, we can actually see that theory tested. In an episode of Secret Science on ABC (Australian Broadcasting Company), a handful of babies sat on the floor surrounded by toys and a couple of well-trained, non-venomous snakes. If you have a fear of snakes, brace yourself but give it a chance—it's as informative and fascinating as it is mortifying.

The host's reaction is so relatable, especially the shudders and the gagging. But clearly the babies were unfazed by the serpents slithering around them. One of them even tried to bite the poor snake, for goodness sake. (It hardly seems necessary, but I should probably insert an obligatory disclaimer here: This is a controlled environment with snakes that are known to be safe with handlers right there, so please do not attempt this with any snakes and babies at home.)
Measuring fear in babies is, of course, a bit of a challenge. It's not like an infant can say, "I'm scared," and babies are known to cry or startle for all kinds of reasons that might not be related to whatever stimuli is around them. An analysis of studies done on babies and fear published in the journal Developmental Psychology in 2020 found that babies react more quickly to commonly assumed fear triggers, but the evidence doesn't show that they are actually afraid of them.

"Most infants are not afraid of snakes, spiders, heights, or strangers," write study authors Vanessa LoBue and Karen E Adolph. "Instead, they differentiate these stimuli from others, they explore these stimuli to learn about them, and they evaluate the meaning of these stimuli relative to the environment. Although fear of snakes/spiders, heights, and strangers might be adaptive in some instances, heightened attention to these stimuli, the ability to perceive affordances for action when presented with these stimuli, and the ability to evaluate their meaning based on context is far more adaptive: These behaviors encourage infants to explore new things while maintaining the flexibility to develop a fear if they discover that a stimulus is truly threatening."
Learning what to fear from caregivers is an important adaptation, not just among humans but among many animal species as well. Rescued baby orangutans had to be taught to fear snakes by human caregivers at Borneo Orangutan Survival, for instance. Snakes are actually dangerous sometimes, so it's wise to instill some sense of fear of snakes in the wild.
Learning to fear something fear-worthy is a tricky business for humans, though. People are complex and an overreaction might lead to an irrational anxiety response rather than a healthy fear. We may have the cognitive abilities to understand the context and circumstances in which fear is warranted or not, but that doesn't mean we are always able to access those abilities in the face of a fight, flight, or freeze response.
Keeping fear in the reasonable realm is important, and knowing that babies start off without fear of snakes might help inform the way we should react in front of them in order for them to learn the wisdom of fear without it going too far.
