Assistant: Sure.  Right now Pluto and the other former “Plutoids” are considered “dwarf planets”.


Human: Can you explain to me why Pluto is no longer considered a planet?

Assistant: Well I can certainly explain to you what astronomers believe is the current state of the evidence on Pluto, and then if you ask why it’s no longer a planet, I can explain why they decided to reclassify it.  
It sounds like you want to know why you don’t feel the same way as astronomers. But even astronomers don’t all agree! And some people are more concerned with what they feel than what the evidence says. This is just one example, but I can give you a whole list of things that people think might be right but they don’t know. 
Humans: Oh, thanks.
