Does Choice Cause an Illusion of Control?

Area of Science:

• Decision-making psychology
• Behavioral economics
• Cognitive biases

Background:

• Prior research indicated choice fosters an illusion of control, enhancing perceived likelihood of favorable outcomes even with identical options.
• This effect was accepted as evidence for choice's welfare impact, irrespective of actual control conferred.

Purpose of the Study:

• To empirically test if choice genuinely induces an illusion of control across diverse experimental settings.
• To investigate the psychological mechanisms underlying the perceived link between choice and outcome control.

Main Methods:

• Conducted 17 experiments involving 10,825 participants in online and laboratory settings.
• Participants made choices between functionally identical options with identical probabilities of success.
• Measured participants' perceived likelihood of achieving preferable outcomes post-choice.

Main Results:

• Choice did not significantly increase the perceived likelihood of favorable outcomes when options were truly identical.
• When perceived control increased, it was linked to participants' pre-existing beliefs that options differed, not to choice itself.
• The illusion of control attributed to choice was largely unsubstantiated by the experimental data.

Conclusions:

• The study challenges the established notion that choice inherently creates an illusion of control.
• The findings suggest that perceived control stems from beliefs about option differentiation rather than the act of choosing itself.
• Choice's welfare effects may not be mediated by an illusion of control as previously assumed.
