So, you’re saying for thousands of years nobody knows about Pluto. Then people suddenly start obsessively monitoring the night sky and enumerating every object they can see in a big journal. They start building bigger and bigger telescopes, blowing enormous sums of money on this seemingly pointless hobby. Then spending the most productive years of their lives sleeping through day so they can wake up in the middle of the night and count celestial objects. And then you’re telling me Pluto caused Autism?

I think you’ve placed the cart before the horse.
