I look at personality typologies in general as approximations. If you actually want to get to know a person, get to know them. But when you need to make a snap judgment about how someone might see the world and react to you, on very little information, it's handy to have a general archetype as guidelines. You can fill in all the details later.
It's not unlike Carmack's fast inverse square root, a Bloom filter, or how Google hasn't used PageRank since 2006 (instead substituting a cheaper-to-calculate approximation). Yes, they give wrong answers. But the answers are usually close enough that when you lack the computing power to get a better result, they'll do.
