Over the centuries, scientists have offered four distinct hypotheses to explain the phenomenon. There is the original “tuck and turn” model, in which the cat pulls in one set of paws so it can rotate different sections of its body. Nineteenth-century physicist James Clerk Maxwell offered a “falling figure skater” explanation, whereby the cat tweaks its angular momentum by pulling in or extending its paws as needed. Then there is the “bend and twist,” in which the cat bends at the waist to counter-rotate the two segments of its body. Finally, there is the “propeller tail,” in which the cat can reverse its body’s rotation by rotating its tail in one direction like a propeller.

Maybe our lives have a path dependency. Some people get early access to upper-class culture. This kicks off a feedback loop where they learn to like that culture more, are more accepted upper-class social circles, get more knowledge and “better” taste, and eventually get economic opportunities (like jobs) and social opportunities (like marrying high-class people).
