The main purpose of this study examined whether the IAT could control social desirability effectively. Four experiments were conducted to investigate the fake-ability of the IAT, durability of the faking, the prerequisite of the faking and the transfer of the IAT experience. We found (1) The participants could cover up their true implicit attitudes through some kinds of response strategy ,which made the individual implicit attitude and collective implicit attitude distorted. The typical strategy of faking was to balance the compatible and noncompatible combinations by deliberately going slowly in compatible condition and responding rapidly for the noncompatible condition. (2) The faking of IAT probably must be based on subjects’ prior IAT experience. And the IAT experience needn’t belong to the same psychological or social domain. It would be helpful to fake the IAT successfully if the subjects’ had known well the mechanism of IAT. (3) It seemed that the successful faking of IAT could only last for a given period of time. The nearer was the IAT experience, the higher was the possibility of successful faking. In summary, the IAT is not immune to social desirability.
