As a rule, "pop history" is full of shit and is probably better considered misinformation than anything else. I probably don't I know of a single general-audience history/anthropology book that doesn't horrify scholars of the field.

As unfortunate as it is, studying cause-and-effect is extremely complex. If it's even theoretically possible to distill it down to easily digestible ideas, that's well outside our current technical capabilities.

There's usually going to be some true and interesting information in these books, but it will be too deeply embedded in a narrative that is misleading.
