> A poll of students taken at Pomona College in 2014 found that 5 percent of them identified as "disabled". That same poll administered in 2019 found that the figure had grown to 22 percent. A nearly fourfold increase in so brief a surely tracks the explosive growth of a culture of systemic advantage seeking; but it likely also indicates a changing perception of the self, a higher threshold of sensitivity to the vicissitudes of everyday life, and an overall normalization and valorization of the condition of disability.
It doesn't necessarily say that at all. In a country with thousands of colleges and universities, I don't think you can rule out chance. (Also, Pomona has 1500 students.)
Even if we saw a large increase across the U.S., it could also be due to increasing numbers of correct diagnoses (rather than overdiagnosis or fraudulent diagnosis) or a change in what conditions count as "disabilities." People considering, say, certain mental illnesses disabilities that they didn't before, that is an shift worth studying and commenting on, but not necessarily one caused by "systemic advantage seeking" or a "higher threshold of sensitivity".
