... The Drake Equation: Adding a METI Factor . ... METI (Messaging to Extra-Terrestrial Intelligence) is an activity, which I believe to be an inherent attribute of advanced civilizations. In order to account for the true prevalence of communicative civilizations (that is, those that engage in METI), I suggest we introduce a METI factor f m into the classical Drake Equation . ... f p = The fraction of those stars with planetary systems . ... Then the METI factor f m should be quite small, about 0.01. ...
