That's a great video, and obviously she is very qualified to speak to this subject. I don't see how this shows that the GP comment is "right" in its assertion that this is just an effect of biased sampling. I only had time to look at the first few minutes, but around 6:50 she does say that our solar system is "not that common", which she quantifies as "it could only be as much as 10-20% of star systems". Maybe that means <= 10-20%? So, this does not seem to contradict anything Vogt and Brown were quoted as saying. Incidentally, I wasn't going by the statement in the NPR article, but also by the press release from UCSC (http://news.ucsc.edu/2012/12/tau-ceti.html http://news.ucsc.edu/2012/12/tau-ceti.html), Vogt's home institution. I don't think that quote is subject to journalistic mangling.
