I will include a question on my upcoming survey asking, "How would you describe the shape of the Earth?" The options are:

Flat

Round (spherical)

Oblate spheroid

Approximately an oblate spheroid with slight pear-shapedness

Geoid

Approximately a geoid, but with imperfections due to surface features that don't exactly match the ideal equigeopotential surface

Dinosaur-shaped

Hyperbolic plane

Other

Aside from the goofy options (Flat, Dinosaur-shaped, and Hyperbolic plane) and Other, I will find the median response of the remaining options, ordered from least pedantic (spherical) to most pedantic (approximately a geoid). The least-to-most pedantic ordering is the same as the ordering of options here. If the median response is between two options, I'll resolve to both of them equally.

See **Plasma's Manifold Survey** for other questions about the survey.

The survey is officially out! You can take it here: https://forms.gle/xZqWVxuY5irgLigu9
