Help needed: Darwin on confirmation bias

Apparently, Charles Darwin said that when he heard something that did not fit his theory, he wrote it down, otherwise he tended to forget it.

Can anyone give me a reference for this?


UPDATE: Thanks to David Schweiger (via Steven Hamblin’s blog), we have the answer. It’s from Darwin’s Autobiography (p. 123):

I had also, during many years, followed a golden rule, namely, that whenever a published fact, a new observation or thought came across me, which was opposed to my general results, to make a memorandum of it without fail and at once; for I had found by experience that such facts and thoughts were far more apt to escape from the memory than favourable ones. Owing to this habit, very few objections were raised against my views which I had not at least noticed and attempted to answer.

How to do history of political thought

Interpreting textsHere is my draft chapter on how to interpret texts, for a book on methods in political theory that I’m editing for Cambridge University Press.

I’m keen for comments – however critical! The only problem is that I need comments by August 1st if possible, as I’m submitting the book manuscript on September 1st. Sorry for the crazy deadline.

I’m particularly keen to hear from current graduate students (MA or PhD), or advanced undergraduates, as that is who the chapter is aimed at.

Even if you’ve never met me, I’d love your criticisms and suggestions! Please download the article and email me at Adrian.Blau [at] – thanks!
