The Fermi Paradox: The Stay at Home Hypothesis I (a.k.a., The Reluctant Traveler Hypothesis)

LuggageThe first SAHH suggests that it is anthropomorphic to simply assume that other species are either interested in interstellar colonization or communication and that our own desires to do so represent a rarity in the cosmic arena. If other species do not find either of these subjects to be of any interest, we should expect to find ourselves in a silent universe.

Critics of the first SAHH suggest that it stretches credibility to presume that no other species have any interest in these things and that we are unique. They note that this is particularly hard to accept since you only need a single colonizing species to arise in order for the presence of intelligence to become quickly ubiquitous (see the First Come, First Serve Hypothesis). Supporters of the first SAHH counter that, even in our own case, we have only made the most furtive efforts at broadcasting our presence and that merely colonizing our own solar system has been something we haven't even attempted due to a profound lack of interest. As such, a reluctance to take up the challenge of colonizing the galaxy may well be the norm and that interstellar species may be so rare that our galaxy has yet to produce one.
