Title: Can we infer social preferences from the lab?
Subtitle: evidence from the trust game
Description: "We show that a measure of reciprocity derived from the Berg et al.  (1995) trust game in a laboratory setting predicts the reciprocal behavior of the same subjects in a real-world situation.  By using the Crowne and Marlowe (1960) social desirability scale, we do not find any evidence that a desire to conform to social norms distorts results in the lab, yet we do find evidence that it affects results in the field"--National Bureau of Economic Research web site.
