AB  - Literature on consumer choice has demonstrated that the inclusion of an inferior 
      alternative choice (decoy) can increase interest in a target product or action.
      In two online studies, we tested the impact of decoys on the probability of
      previous non-intenders to have a screening test which could significantly lower
      their chances of dying of colorectal cancer. We find that the presence of a decoy
      increased the probability to choose screening at the target hospital (over no
      screening) from 39% to 54% and 37% to 59% depending on how many hospital
      attributes were communicated and how strongly the decoy was dominated by the
      target. We also show that the presence of the decoy was associated with lower
      levels of reported decisional complexity while not undermining information
      seeking and knowledge acquisition. These findings offer a 'proof of principle'
      that decoys have the potential to increase screening uptake without negatively
      influencing informed choice.
