Globalization typically reduces local differences. Shake Shack in Toronto is a lot like the Shake Shack in Dubai. But does this also apply to the inside of our homes?

This is a question that was recently asked by researchers at the MIT Senseable City Lab. And to answer it, they used AI to analyze over 400,000 interior images across 80 global cities. The images were taken from Airbnb, but they did also do a "robustness check" and pull images from Craigslist, Zillow, Zigbang, and Ohou.

What they discovered was that geography still matters. Local customs persist, and when two cities are close to each other, they tend to share visual similarities — both in terms of the objects that show up and how they look. So much so that their model was able to predict a city with an accuracy of about 45% just by looking at interior photos.

This is somewhat surprising to me as I thought that Airbnb listings might have skewed toward homogeneity. There can also be an Airbnb aesthetic. But local tastes and traditions still exist. For example, the study found that Turkey seems to place a high level of importance on curtains. Big drapery people over there, apparently.

At the same time, globalization is doing things. One of their findings was that cities with high flight volumes tend to exhibit more visual similarities. This says something about the value of physical connectivity. We're, of course, all connected digitally, but apparently that's not the same as getting on a plane and physically being somewhere.

"The same, but different" feels like an accurate description. To download a copy of the study, click here.
