While Ilana Horn doesn't mention anyone in particular in this post, I think her "unicorns" are the super-collegial math teachers we know on Twitter. Yes, they are special teachers and do not represent the majority, but that doesn't mean they should be ignored. The unicorns can set a great example for others, and when it comes to research it's helpful to experiment with a treatment under ideal conditions (like with unicorns) before trying the treatment under typical conditions (unicorns in training).
