A hard-to-watch experiment demonstrates that babies aren’t naturally afraid of snakes
Letting snakes loose in a room full of babies? Fascinating, but soooo uncomfortable.

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.

Resurfaced video of French skier's groin incident has people giving the announcer a gold medal
"The boys took a beating on that one."
Downhill skiing is a sport rife with injuries, but not usually this kind.
A good commentator can make all the difference when watching sports, even when an event goes smoothly. But it's when something goes wrong that great announcers rise to the top. There's no better example of a great announcer in a surprise moment than when French skier Yannick Bertrand took a gate to the groin in a 2007 super-G race.
Competitive skiers fly down runs at incredible speeds, often exceeding 60 mph. Hitting something hard at that speed would definitely hurt, but hitting something hard with a particularly sensitive part of your body would be excruciating. So when Bertrand slammed right into a gate family-jewels-first, his high-pitched scream was unsurprising. What was surprising was the perfect commentary that immediately followed.
This is a clip you really just have to see and hear to fully appreciate:

It's unclear who the announcer is, even after multiple Google inquiries, which is unfortunate because that gentleman deserves a medal. The commentary gets better with each repeated viewing, with highlights like:
"The gate the groin for Yannick Bertrand, and you could hear it. And if you're a man, you could feel it."
"Oh, the Frenchman. Oh-ho, monsieurrrrrr."
"The boys took a beating on that one."
"That guy needs a hug."
"Those are the moments that change your life if you're a man, I tell you what."
"When you crash through a gate, when you do it at high rate of speed, it's gonna hurt and it's going to leave a mark in most cases. And in this particular case, not the area where you want to leave a mark."
Imagine watching a man take a hit to the privates at 60 mph and having to make impromptu commentary straddling the line between professionalism and acknowledging the universal reality of what just happened. There are certain things you can't say on network television that you might feel compelled to say. There's a visceral element to this scenario that could easily be taken too far in the commentary, and the inherent humor element could be seen as insensitive and offensive if not handled just right.
The announcer nailed it. 10/10. No notes.
The clip frequently resurfaces during the Winter Olympic Games, though the incident didn't happen during an Olympic event. Yannick Bertrand was competing at the FIS World Cup super-G race in Kvitfjell, Norway in 2007, when the unfortunate accident occurred. Bertrand had competed at the Turin Olympics the year before, however, coming in 24th in the downhill and super-G events.
As painful as the gate to the groin clearly as, Bertrand did not appear to suffer any damage that kept him from the sport. In fact, he continued competing in international downhill and super-G races until 2014.
According to a 2018 study, Alpine skiing is a notoriously dangerous sport with a reported injury rate of 36.7 per 100 World Cup athletes per season. Of course, it's the knees and not the coin purse that are the most common casualty of ski racing, which we saw clearly in U.S. skier Lindsey Vonn's harrowing experiences at the 2026 Olympics. Vonn was competing with a torn ACL and ended up being helicoptered off of the mountain after an ugly crash that did additional damage to her legs, requiring multiple surgeries (though what caused the crash was reportedly unrelated to her ACL tear). Still, she says she has no regrets.
As Bertrand's return to the slopes shows, the risk of injury doesn't stop those who live for the thrill of victory, even when the agony of defeat hits them right in the rocks.
