Gell-Mann Amnesia Effect

Michael Crichton's observation (named after physicist Murray Gell-Mann): you read a newspaper article about a topic you know well and notice it's full of errors, oversimplifications, and misunderstandings. Then you turn the page to an article about a topic you DON'T know well and inexplicably trust it as accurate—forgetting that the same newspaper that got YOUR topic wrong is equally likely to get OTHER topics wrong. The amnesia is instant and universal: the demonstrated unreliability of a source in one domain doesn't reduce trust in that source for other domains.

When to use it

When consuming media about topics outside your expertise; when evaluating generalist sources that have demonstrated errors in your field; when designing information intake systems that need to account for source reliability; when calibrating trust in any information source.

How it can help

Apply the skepticism you have in your domain of expertise to ALL information consumption. If you know the news gets medicine wrong, assume it also gets economics wrong. Seek expert sources for important topics.
