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

Resolves to the percentage who say "Dinosaur-shaped". If it's on the border of two bins, resolves to both bins 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
