Briefly stated, the Gell-Mann Amnesia effect is as follows. You
open the newspaper to an article on some subject you know well.
In Murray's case, physics. In mine, show business. You read the
article and see the journalist has absolutely no understanding
of either the facts or the issues. Often, the article is so wrong
it actually presents the story backward -- reversing cause and
effect. I call these the "wet streets cause rain" stories. Paper's
full of them.
In any case, you read with exasperation or amusement the multiple
errors in a story, and then turn the page to national or
international affairs, and read as if the rest of the newspaper
was somehow more accurate about Palestine than the baloney you
just read. You turn the page, and forget what you know.
