I think a better question is: How did the median get so much better over 150 years, and why can't it keep getting better?
150 years ago, the average person was illiterate, poorer (in all senses of the word) and less connected to the world around them. Over a 100 year old grind, schooling fixed all that. Why can't it keep going? So the outlier, super special "phenom" today is the median of tomorrow.
> 150 years ago, the average person was illiterate
Not true in the case of the US, which famously adopted a culture of universal literacy earlier than the rest of the world. By the mid-19th century, literacy rates among whites were not much different than they are today. It is one of the bright spots of American history; they took literacy very seriously for complicated historical reasons. Their book consumption per capita was also the highest in the world by a very large margin back in those days, which lends evidence.
It may or may not be relevant to your point, but at least in the US the idea that the average person was illiterate is ahistorical. They were the best read population in the world 150 years ago, and took some pride in that.
