Across Cultures, People Combine Reference Frames to Orient Themselves:
When walking through an unfamiliar city, we might rely on different types of directions. Head east out of the train station, take a left at the stop light, turn at the building with the mural.
To move through complex environments and keep track of where objects are, people use reference points either in relation to their own body (for example, to their left) or based on features of their environment (next to the window, across from the door).
As someone moves around, the body-based references, called egocentric reference frames, may change, whereas the environmental references, allocentric reference frames, stay the same. For instance, a tree on the left when walking in one direction is on the right when walking in the other direction, but the tree is always next to the mailbox.
Different cultures use different reference frames, perhaps as a product of language. Americans, who are thought to prefer body-based references, tend to talk egocentrically.
"We say things like, 'You have some food on your left cheek,'" said Benjamin Pitt, a research fellow at the Institute for Advanced Study in Toulouse, in an interview with the Observer. "We would never say that you have some food on your down-river cheek or on your east cheek, but other cultures do."
Additionally, the physical reality of where we live influences our frames of reference. Rather than looking left and right to cross a street, people growing up in the Amazon rainforest cross rivers by looking upriver to check for hazards.
In the natural world, "There's really no reason or very little reason to keep track of left–right spatial distinctions," said Pitt. "Instead, there's good reasons to keep track of allocentric spatial distinctions. It's all about where things are in the environment, and the environment tends to not be organized with respect to our bodies."
[...] Pitt suspects people use different references for left–right and front–back because keeping track of left–right spatial distinctions is harder.
"We have expressions like, 'No, your other left,'" said Pitt. "Nobody is confusing their front from their back. Nobody's like, 'No, your other front.' It's so completely obvious, which is your front and which is your back."
For those more difficult left–right distinctions, people may abandon body-based references for easier environmental references.
"You can just pick something in the environment that's sitting there staring at you," said Pitt. "You don't have to worry about whether it was on your left or your right because that's too confusing."
But people don't use environment-based references for everything. It seems a combination is best, regardless of where you live.
"If you want to move your body through the world, then you're going to need to integrate these things," Pitt said.

People do not use culture or cultural references any more. They stare at their phones and google-map so they do not have to ask strangers. Even if said map leads them down weird, and wrong, paths.

Yes, Nixiwaka did check upriver for hazards.
Unfortunately, the black caiman was downriver.
On the plus side, it won't be hungry again until tomorrow.
TL;DR: ...perhaps Nixiwaka should have looked left and right.

I remember when I was visiting Hong Kong that they had writing at most crossings to look right, left, right because the direction of travel of vehicles was opposite the mainland.

Some things better one way, some better another - a very generalizable observation.

It's actually really hard to define "left" rigorously without somehow referencing... well... left.
Most notably because it only works from one fixed viewpoint and to understand it you have to put yourself into the position of others.
But "left" is a difficult concept, far more so than "towards where the sun sets" or "upstream". It's why kids often struggle with it and the only way to help them is to label things and have them memorise which side of themselves is left or right based on a slight difference between the two (e.g. a preference for right-handedness).
But left / right is actually difficult to define without being self-referential.

When my kids were smaller they were taught two ways:
"The hand that makes an L with pointer and thumb is the L for Left" I think there's a nursery rhyme song for this maybe a Barney song I can do without hearing again. Or the Wiggles. You'd think Australians would have more trouble with up vs down what with being on the southern hemisphere. "turn toward the equator" "nooooooo I meant turn south not north" Are Australian kids taught north is up on the map? Its a semi-serious question in the spirit of the linked article.
"I see you're right handed so right is the hand you write and color and crayon with". They were right handed doing art stuff before they know left from right, I think. It happened pretty quickly anyway.
I would never overlook sheer child/teen/YA stubbornness and refusal to pay attention. My kids still go where they please when pushing a shopping cart, etc, they simply don't care if a parent tells them three times to "turn right we are getting lettuce from the produce department" they'll just wander where they want when they want sometimes. There's a difference between knowing left from right, and caring about arbitrary instructions they're uninterested in.
