What are the characteristics of Cartesian method doubt?

In simplest terms, it is using doubting and questioning to prove everything that cannot be explained by a logical explanation, leaving only those things that are explained logically left to be believed. It would lead someone to believe that anything that doesn't have something rooted in logic is false. It requires excessive and almost extravagant thinking to do so, since almost everything can be looked at this way somehow.

The whole thought process behind the method can, eventually, trace everything back to creation, using the logic that everything had to come from some place to create it to start with.

It's a fun little method at times. Hope this helps some.
