Cheating the lie detector: faking in the autobiographical Implicit Association Test.

The autobiographical Implicit Association Test (aIAT) was recently introduced in this journal as a new and promising lie-detection tool. The initial report found 91% accuracy in determining which of two autobiographical events was true. It was suggested that the aIAT, unlike other lie-detection tests, is resistant to faking. We investigated whether participants can strategically alter their performance on the aIAT. Experiment 1 showed that participants guilty of a mock theft were able to obtain an innocent test outcome. Two additional experiments showed that guilty participants can fake the aIAT without prior experience with the aIAT and when a response deadline is imposed. The aIAT is subject to the same shortcomings as other lie-detection tests.
