Fast and furious responses followed, screenshots of the posts went viral on various social media platforms and the entire nation of Sweden took a beating as people berated their rude habits and lack of basic hospitality. The hashtag #Swedengate trended on Twitter for days as people shared all manner of negative impressions of (and in some cases, direct experiences from) Swedish culture.

I'm not here to defend Sweden wholesale, as I'm sure there are plenty of legitimate criticisms, as there are for every culture. However, when it comes to something like not feeding guests in your own home, it seems likely that there's some kind of explanation beyond "these people are just rude." Much like noodle slurping in Japan, one culture's rude can be another culture's polite.

As it turns out, there are a few explanations for it.

Part of Sweden's food culture is a combo of its long winters and culture of independence.

Professor Hakan Jonsson, a food studies professor at Lund University in Sweden, told The New York Times that some of the resistance to feeding guests stems from the days when food harvests had to be stored for many months during the long Nordic winter. Spontaneous dinners were traditionally not part of the culture, as families had to carefully plan and ration their food stores.

Independence is also a strong cultural value in Sweden, and rather than seen as generosity, feeding another person's child could be seen as a criticism of that family's ability to provide for their children.

“There has been a very strong urge of independence, to not rely on others’ good will for having a good and independent life,” Professor Jonsson told The Times.

(Hmm, now the entire IKEA model makes sense. Careful precision in design, but then, "Here, you're on your own to actually build it. Good luck.")

Others have shared similar explanations, saying that feeding someone else's child is in some ways considered rude, either because it's viewed as a judgment on the parents' ability to feed their children or as interfering with a family's own dinner.

"Swedes cook for the people they expect (family). Precise portions. We don't mind guests, just tell us in advance and we'll add one more. And in Sweden, it's understood, you don't eat at a friend's house unannounced. No big deal here," wrote one Twitter user.

Those explanations didn't stop people from cultures that place a high value on hospitality from criticizing the practice, of course. Not feeding a guest in your home is the peak of rudeness in certain cultures, so how could this practice be seen as OK in any way?

Part of Sweden's not-feeding-guests culture may be rooted in a history of shame for 'owing' people.

Another explanation shared on Twitter from an "amateur historian and sociologist" provides more historical context for the practice. It's a bit lengthy, but the gist is that this not-feeding norm isn't unique to Sweden, but common to Norse cultures in general and even somewhat common in Norman England and France. According to this explanation, it has to do with the historical "honor/shame economy" of Viking culture being a source of violent conflict.

"In Norse culture, hospitality (providing food, drink, lodging) was a duty of higher status individuals towards people of lower status, but the act of receiving hospitality created an obligation or debt on the part of the recipient," @WallySierk wrote. "So, hospitality not only brought honor to the giver, it had the potential to bring shame to the recipient. Norse culture, and as it progressed through the Middle Ages, was incredibly personally violent. People fought duels, violently extracted debts and squeezed renters."

"One of the challenges of the Protestant church in Scandinavia post-30 years war was to create a culture that tamped down on personal violence and civic unrest," they continued. "Since the root of a lot of the interpersonal violence was competition for status and extraction of payment, the Church, with the framing of early Protestant Humanists, began to promote the ideal of the free member of society, owing no one and owed nothing. If the culture could get rid of the interactions that caused friction, people could live more peaceful lives."

The thread explains that inequality and industrialization in the 1700s and early 1800s pushed Scandinavians to emigrate to America and other colonies, leading some people in power to manipulate debts, which created a lot of pain.

"When people were able to escape debt, they felt a lot better. So, for the sake of egalitarianism and reduction of conflict, they created a society that minimized the creation of debt and obligation, and maximized the ability of the individual/family to be self-sufficient. This 'not feeding the neighbor kids' weirdness Is about maintaining peace in the community."

From reading replies from Swedes, it appears this practice is common, but not necessarily universal. It also appears to be primarily about guests who are not planned for in advance, not a blanket "we don't do hospitality" norm. Still, it is a stark contrast to cultures in which offering food to any guest in your home is simply par for the course. The idea that you would not only not offer, but actively not serve a guest food is a complete anathema in many countries and cultures around the world.

But when you dig into the roots of why those norms exist, it's not quite as blatantly rude as it seems. Cultural norms rooted in historical struggle take a long time to change, even when those struggles are no longer front and center.

All I'm saying is let's give the Swedes a teensy bit of grace on the food front. They may come across as stingy to many of us, but in the context of their own history, it makes some sense. Plus those IKEA Swedish meatballs are hard to beat.
