Unconscious thought does not appear to improve complex decision-making performance. Conscious thought, however, seems to hinder decision quality compared to immediate decisions, challenging prior findings.

Area of Science:

  • Cognitive Psychology
  • Decision Making Science

Background:

  • Prior research suggested unconscious thought enhances complex decision-making.
  • Dijksterhuis et al. (2006) proposed powerful unconscious deliberation mechanisms.

Purpose of the Study:

  • To re-evaluate the role of unconscious thought in complex decision-making.
  • To challenge the interpretation of previous findings on unconscious thought.

Main Methods:

  • Utilized a similar experimental design to Dijksterhuis et al. (2006).
  • Introduced an additional 'immediate' decision-making control condition.

Main Results:

  • Decision quality in the 'immediate' condition was comparable or better than the 'unconscious' condition.
  • Decision quality in the 'conscious' condition was lower than the 'immediate' condition.

Conclusions:

  • The benefit of unconscious thought in complex decisions is questionable.
  • Conscious processing may disadvantage decision-making quality.
  • Further research is needed to cautiously consider the role of unconscious thought.
