Quote of the Day: “When the facts change, I change my mind. What do you do sir?”

without comments

When the facts change, I change my mind. What do you do sir?

Although this quote is commonly attributed to John Maynard Keynes, where it has been said that this was his response to a U.S. General that accused him of waffling on issues.  But, some research by the Quote Investigator suggests that it was originally from Dr. Samuelson where he said:

Well when events change, I change my mind. What do you do?

In either case, the sentiment is an important one with regards to scientific thinking.  We must be willing to change our minds as facts and events change.  In fact, one could define learning as the act of changing ones mind as better information is received.
