Failure to Replicate the Unconscious Thought Advantages

In this study we tried to replicate the unconscious
thought advantage (UTA), which states that complex decisions are
better handled by unconscious thinking. We designed an experiment
in e-prime using similar material as the original study (choosing
between four different apartments, each described by 12 attributes).
A total of 73 participants (52 women (71.2%); 18 to 62 age:
M=24.63; SD=8.7) took part in the experiment. We did not replicate
the results suggested by UTT. However, from the present study we
cannot conclude whether this was the case of flaws in the theory or
flaws in our experiment and we discuss several ways in which the
issue of UTA could be examined further.
