As with "afantasia" a few years back, we seem to keep encountering places where the experience and perhaps even construction of minds are very different from each other, and the diversity of brains is certainly fascinating... But underpinning all the reporting I read on it is a fundamental assumption that's very strange to me. A lot of people seem to work under a model where brains and lived experiences should be very similar to each other, and I just don't see that actually bearing out anywhere. So what I often come away wondering is: Why is this assumption so pervasive?
