Hippo: Hey, Panda, did you see this study that says that students consistently give lower teaching evaluations to hippos than to pandas?
Panda: How do we know that’s true? I’m very sophisticated statistically, not to mention ridiculously cute due to the fact that I am a panda, and I can tell you that that study has a lot of flaws.
Hippo: But there are a lot of other studies like this, so can we just assume for the purposes of our conversation that it’s true?
Panda: Ok, let’s make that assumption. So maybe hippos get worse evaluations because hippos are just lousy teachers—maybe you all need to learn how to teach.
