Here's something else to think about. Electron flow is not current. In a wire, the current flows at nearly the speed of light. But the electrons move at, say, a millimeter per second. (Actually, they move much, much faster than that as they whiz around in their orbitals. But the net drift of the electrons is a snail's pace.)

Electrons flow from the more negative potential to the more positive. Work must be exercised to rid electrons thus creating a 'positive' potential which is really the absence of electrons. Loose electrons in a more negative material will be drawn towards the more positive material.

Intuition makes many think the opposite is really happening, we have a 'higher' potential' object and abundance of ground potential materials, so intuitively it was/can be thought that the flow is from positive to negative as the positive potential created the observed effects

Coldness doesn't flow into you in the winter, your giving your heat up to the colder fluid.. same sort of deal
