But it is known that people have a bias towards tangible figures, like meaningful probabilities and round numbers. This heavily distorts the range of imaginable possibilities. Probabilities are real numbers between 0 and 1. For example, 1.E-301 is one of them. But if one is to take that probability out of a hat people just blatantly ignore it. >The sheer hubris that there isn't any life in any of the other trillion galaxies usually makes people reconsider. Hubris is on both sides of this, isn't it? On the face of little to no evidence, how can we estimate such probabilities?
