Langer's experiments and skill cues
Langer (1975) gave office workers $1 lottery tickets, letting some choose their own and assigning tickets to others. Asked before the drawing what price they would accept to sell their ticket, those who had chosen their own asked an average of about $8.67, compared with about $1.96 for those assigned one. The outcome was pure chance, but the act of choosing created a sense of control. Langer argued that the illusion grows when cues from skill situations, such as choice, competition, familiarity and active involvement, are mixed into chance situations. Langer and Roth (1975) showed that in a task of predicting coin tosses, people who guessed many correctly early on rated their ability higher, even when their total number of correct guesses was the same. Earlier, Henslin (1967) observed craps players throwing the dice softly when they wanted low numbers and hard when they wanted high ones. Along with the gambler's fallacy, the phenomenon is key to understanding gambling behavior.
Positive illusions and their costs
In a task judging the link between pressing a button and a light turning on, Alloy and Abramson (1979) reported that nondepressed students overestimated their control even when there was none, whereas depressed students judged more accurately. Taylor and Brown (1988) argued that such positive illusions actually help sustain mental well-being and motivation. Thompson (1999) noted that the illusion of control grows when people focus on desired outcomes, are personally involved and have experienced success, and Presson and Benassi (1996) confirmed in a meta-analysis that the effect appears consistently across studies. Wegner and Wheatley (1999) explained the experience of will: when a thought comes to mind just before an action, people feel they caused the outcome regardless of its actual cause. Yarritu, Matute and Vadillo (2014) showed experimentally that personal involvement strengthens the illusion.
Finance, management and the opposite error
Fenton-O'Creevy and colleagues (2003) measured the illusion of control among traders at London investment banks with a computer task. Traders with a stronger illusion received lower ratings from their managers and earned less. Durand (2003) found at the firm level that organizational illusions of control weaken forecasting ability. The phenomenon is closely tied to overconfidence bias, the overestimation of one's ability and accuracy. However, Moore and Healy (2008) showed that people underestimate themselves on easy tasks and overestimate themselves on hard ones. Applying this to control, Gino, Sharek and Moore (2011) showed that people overestimate control when their actual control is low but underestimate it when their control is high. The illusion of control can thus be understood not as one-sided optimism but as a problem of imperfect calibration.
FAQ
- What is the illusion of control in simple terms?
- It is the mistaken belief that you can influence outcomes that actually depend on luck. Feeling that picking your own lottery numbers makes you more likely to win, or that throwing dice hard will give high numbers, are classic examples.
- Is the illusion of control always harmful?
- Not necessarily. Some researchers argue that a moderate sense of control helps sustain motivation and persistence. But in high-risk decisions such as investing or gambling, it can lead people to underestimate their losses.
