Uniformity of motive

In astrobiology, the Uniformity of Motive theory suggests that any civilization in the universe would go through similar technological steps in their development. This theory supports the idea that at some point in their history, advanced alien civilizations would use the electromagnetic medium for communications, and thus would emit radio waves that could be detected by projects such as SETI.

The fact that no artificial EM band communications have ever been detected supports the Fermi Principle, which in conjunction with the Uniformity of Motive theory, and Occam's razor suggests that a civilization that uses this medium is a unique occurrence in Earth's region of the Milky Way Galaxy and perhaps the universe.
