Yes, and scientists don't care. Science, as it has been explained to me by scientists, is a penis length contest, where impact factor and prestige serve as ersatz penises.
But since it props up a myth that senior faculty like to believe (i.e. their shitty old Cell paper is great because Cell is/was great) that's the yardstick. As the director of a CCC once told me, it takes too long to see the impact of papers (citations piling up) so the JIF is used as a proxy.
Sort of like how it takes too long to do good science, so some people just publish whatever garbage they can sneak past the editors (ha fucking ha only serious). There is a LOT of crap in the literature as a result.
