Their brains seem to simplify tasks they have 0 experience with. Things like: owning car, renting an apartment, getting a job are all viewed as something that they will "just do" and don't really seem to raise any concerns.
People do know. What they know might not be so. What is the point of this common sense analysis? Seems like "check your facts" stretched out to an unwieldy length.
