Apparently it was Kuhn, but available citations are paraphrases.

"[According to Kuhn] The old
scientists who became established within the dominant paradigm have to die off first: they will virtually never accept the new paradigm. Only the younger generation of scientists, who don't have the emotional attachment to the old paradigm will be willing to change their minds. As physicist Max Planck once said, 'Science progresses funeral by funeral.'"

Marilyn Ferguson, New Age, August 1982 (quoted at http://www.fha.asn.au/main.html ).

The insight is attributed to Thomas S. Kuhn, THE STRUCTURE OF SCIENTIFIC REVOLUTIONS Second Edition, Enlarged (Chicago: University of Chicago Press, 1970) at http://www.igc.apc.org/awea/wew/othersources/rachel467.html and is paraphrased at that web site thusly:

"Not only is science a popularity contest of ideas, but some scientists hold onto ideas long after the available data have shown them to be untenable. In fact, says Kuhn, the way scientific ideas change completely is not by all scientists changing their minds; it's that older scientists who retain discredited ideas die, and then the only people left are those holding the newer ideas."

I love Altavista. The ability to combine pure boolean queries with ranking keywords is very powerful, but tricky to use. In this case, all it took was a search on "change" NEAR "minds" with the ranking keyword "Kuhn". Both useful hits were in the first page of results.

FWIW, and to stay on topic, I don't think SETI (nor seti@home in particular) are completely useless. Yes, the odds of a positive result are seem vanishingly small; and yes, the assumptions made in conducting the search are homocentric (how else can humans act?) which limits the value of a negative outcome. But there is no way to claim that, after subjecting the data to detailed analysis, we will not know more than we knew before. Deny the value of that and you deny the value of science, which I am not prepared to do.
