Two field experiments investigated the impact of postevent information upon eyewitness descriptions of people. In particular, we examined the effects of information introduced after an event upon witnesses' estimates of weight and age. Informing subjects that a man they had seen had either thrown a heavy object or was a truck driver led to significantly heavier weight estimates than telling them he ran away or was a dancer, respectively. Also, referring to the confederate as either a “man” or “young man” led to significant differences in subjects' age estimates. Additional analyses indicated that neither viewing distance nor subject sex was predictive of either general accuracy or susceptibility to bias.
