Pretty sure that also happens in fields other than the hard sciences. For example, it is said that converts to a religion are usually much more fervent than people who grew up with it (though there's an obvious selection bias).

(The advanced, dark-artsy version of this is claiming with a straight face to never have believed A in the first place, and hope the listener trusts what you're saying now more than their memory of what you said earlier, and if it doesn't work, claim they had misunderstood you. My maternal grandpa always tries to use that on my father, and almost always fails, but if he does that I guess it's because it does work on other people.)
