>>28010823Scientists are busy analysing the data and researching, like they visibly are in every game. The children go out and write up what they see. That's why half of the 'dex entries are ridiculous; they're the writings of excited children.
The Pokedex does a couple of things for the player; it shows you where Pokemon are, gives you their types et.c. But it's main feature, as regards the player, is hinting what they're designed to be... You know, because communicating the world through monster designs is the main part of the series. It's the part you chat about with your friends and the part to helps you learn about the world.
That's also why most dex entries explain a Pokemon through what it's based on in the real world. It's really obvious, mate. It's supposed to be obvious. You're supposed to just figure that out right away.
That's one of the reasons why early route monsters are basic and late game ones are "higher-concept". It's game design. You figure out that one is a rat, one is a pigeon and it sets you up to understand that they're based on things. Further down the line they get more complicated and the pokedex tries to assist you with 'getting' what they are.
Then, when you're out trading with your friends, there's a chance one of them will understand one that you don't. It's social, it's educational, it's representative of the real world.
Catching a Xatu in the game is like coming across a picture of an Aztec thingamajig in person, but it's localised and portrayed as a monster which helps children around the world get more cultured.
Japan specifically was isolated for a long time - they didn't even know they had a tourist industry until about 12 years ago. Due to them being the only country that speaks Japanese and what not, there was a lack of foreign culture available for kids to find out about. Pokemon acts as a sort of an exaggerated encyclopedia for kids to learn about the world.
