Gilovich and Epley have shown that subjects give estimates farther from the anchor (meaning that they are adjusting more) on these types of questions when they are given incentives for accuracy, warned about the biasing effect of anchors, high in Need For Cognition (the dispositional tendency to think things through a lot), or shaking their head (which makes them less willing to stop at a plausible-seeming value; head-nodding produces even less adjustment than baseline).
Shaking their heads? If this is really an effective way to de-bias your thinking a tiny bit...COOL! I will try that!
There have actually been several studies I’ve seen indicating that body-language is a feedback loop rather than just a communication output. Forcing yourself to smile will actually make you slightly happier, etc.
