Top 10 Types of Lists Which Require Most Knowledge to Make

There are thousands of lists on TheTopTens and many different categories of lists. All lists require knowledge. But not all lists are easy to make, some lists require a lot of knowledge to make comparing to other lists. And to me, these lists seem to be require most knowledge to make.

And all these things apply if you are making informative lists.

You can add whatever comes to mind.
