Where does the Pokédex get its information?

That's actually a really good question, I've never thought about it xD
Maybe the Pokedex scans the Pokemon while it's in the Pokeball, and analyzes its features, strengths/weaknesses based on the Pokemon's appearance... perhaps it can somehow scan the Pokemon's brain and get the information from there...

Professor Oak is either a genius for inventing a device that can get all the information from these fascinating creatures just by scanning them, or he's an evil ba***rd for sending kinds out on a dangerous journey for nothing xD

What LightningAlex said, or it could be that Professor Oak already has all of the information, and is just trolling you.

I was thinking more along the lines of it gathering information when it's in a PokeBall as well, but that only applies to the Pokemon's physical feature, such as weight, height, color, etc. I don't see how the PokeDex can gather information about Pokemon and their typical behavior or hunting habits. It's probably just a logical fallacy that are sprinkled all over the Pokemon franchise.

Sounds about right.

"I've studied and researched Pokemon my entire life. I want you to continue my research. Here's a Pokedex. It's empty."

They probably know all of their regions' Pokemon beforehand and send you on your journey without the knowledge because it makes it all the more exciting for an adventurer like yourself; just full of surprises. Where would the fun be in a Pokemon journey if you just went around already knowing each and every one that you meet? Pokemon also have a bunch of different habits, so it could also be to make sure that even more possible data is gained and stored incase someone new happens to get involved in a situation where unknown habits, etc turn up.

That's something that used to bother me once I started getting more and more into the games, but this is how I ended up feeling about it, haha.

Or who knows...maybe it is some huge troll all of the regional professors are pulling off.

Prof. Oak must've researched about the pokemon to learn about hunting rituals and whatnot there are only around 151 pokemon in his area, while the other professors research their own region. But since the Pokedex is technically already complete then the probably just want to see who'll actually finish it. Otherwise, they just want you dead. Or maybe the Pokedex is secretly transferring the data to Route 51 so they can clone the legendary pokemon since their Mewtwo project failed! (Sounds like a good for a hack, right? You may use it) Anyway, I never really cared too much about the Pokedex, because I respect the Pokemon so I only capture 6, I mean what's the point of the other's in the PC if you just want them trapped there?

I've come across a theory about this before: what if the player character is actually the one writing the entries? Like, whenever you catch a Pokemon, he just fills in whatever background info he knows and/or whatever nonsense he can come up with. It'd explain why they tend to make ridiculous exaggerated claims ("Charizard's flames can melt anything!", "Magikarp can leap over a mountain!", etc).

Just a theory, but the Pokeball and the PokeDex are both probably related and connected to some sort of computer containing Prof. Oak's collected data. The Pokeball probably scans the Pokemon caught and finishes and sends some data to the PokeDex so it can be recorded. This probably explained how Paul was able to scan his Pokeball using his PokeDex after catching a Pokemon...

Either that or it just came from Game Freak HQ itself lol.
