Although many researchers have been unsuccessful in doing so, I was able to partially replicate Dijksterhuis' (2004) "unconscious thought" effect. I found that participants who were distracted with the performance of an irrelevant task made better decisions than participants who engaged in conscious thought or participants who made immediatedecisions. Task directions and population differences in the evaluation of option attributes likely represent confounding variables that can disrupt the unconscious thought effect. While Dijksterhuis has argued that his findings necessitate the existence of an unconscious thought process capable of operating in the absence of attention, I suspect that there is a more parsimonious explanation. I suggest that participants may develop implicit preference as they read the attribute statements, and that the behavioral expression of this preference is moderated by thought condition.
