Strategic essentialism is a way of looking at how people group things together. It's like putting things into boxes. You group them together even if they're not exactly the same, because some things that are similar can be treated the same. For example, if you want to talk about cats and dogs, you might say animals instead of cats and dogs. That way, you can talk about all animals at once, instead of having to talk about cats and dogs separately. Strategic essentialism helps people think more efficiently.
