Jerry was home schooled by his uncle, and has been told the earth is flat, and concluded the earth is flat.

Jerry is wrong. When Jerry tells his friends the earth is flat, he is not lying. Just wrong. When Bob says the earth is flat, he is lying. Knowing full well it is round.

Jane was taught that the earth is stretched a little bit because of the centrifugal force of it’s spinning.

Jane is also right.

Bob and Jane had a conversation about the shape, and experienced a thing called nuance. It’s not perfectly round after all.
