Why the taboo against naming discoveries after yourself? It is often considered a very bad idea to try to name a discovery (a law, phenomenon or an invention) after yourself.

On the other hand, there are many species names which seem to be a bastardized Latin of the discoverer's name. With gene names, I'm not sure, but I've seen many frivolous gene names, such as those inspired by cartoon characters. I wonder if you could get away with naming a gene after yourself if you wanted to.

In other cases, such as names of synthetic strains and plasmids, it is in fact preferable to use the researcher's name. Off the top of my head, I recall GFAJ-1 - the surrounding controversy aside, given all the work she's done, what is so wrong about her wanting to name it after herself?

However, why is this so? Apparently, it can even advance to an extreme where many years after a discovery has become established and associated with Dr. Jones, when he writes a review article on applications of the Jones Effect he will still carefully avoid acknowledging this name.

Isn't it convenient to simply name something after yourself when no clever acronym exists? Isn't doing the work of the discovery enough to earn the right to name a thing? Doesn't the fact that the discovery is important enough to be published automatically imply that it's important enough to be named after oneself?
Traditionally naming after scientists has been considered an honour bestowed upon somebody by their colleagues. This is why there are plenty of such names in latin animal or plant names. one very good example is Strigiphilus garylarsoni, a chewing louse, named after Gary Larson, author of the Far Side.

Naming can also be subject to strict laws. In some countries, it is, for example, not possible to name official places after persons until after they have passed away. This is to prevent people to inflate their own reputation while alive (it is quite easy to see where such behaviour is going overboard). But, this is a digression.

The main point is that etiquette indicates that one does not name things after one-self, one can hope that the work is so appreciated by others that a naming occurs. It is probably also a good thing that everything we discover is not named after a person. I drove my Smith at 120 kiloJones per Dickens.
