It's really not a question of not having a taste for it, or not being able to develop it. I'm 100% certain I could develop it, as my grandmother has -- due to seemingly inherent interest -- consumed ever spicier dishes.
My father, uncle, and I have no interest in developing our taste buds to consume ever spicier foods in the way my mother's family does. I simply am happy to eat whatever. So many things taste good, there is no reason to eat incredibly spicy food. That being said, half of my spice tolerance (which is incredibly incredibly high) is due to being forced to consume it by my mother.
