    Input: The authors tested the thesis that people find the  Monty Hall dilemma ( MHD ) hard because they fail to underst and the implication s of its causal structure , a collider structure in which 2 independent causal factors influence a single outcome . In 4 experiments , participants performed better in versions of the MHD involving competition , which emphasizes causality . This manipulation result ed in more correct responses to questions about the process in the MHD and a counterfactual that changed its causal structure . Correct responses to these questions were associated with solving the MHD regardless of condition . In addition , training on the collider principle transferred to a st and ard version of the MHD . The MHD taps a deeper question : When is knowing about one thing informative about another 
    Output:
    
This review provides novel insights by means of its holistic approach of the MHD : At each phase , there are reasons to expect that people respond suboptimally .
Given that the occurrence of only one cause is sufficient , it is not surprising that suboptimal responses are so widespread and people rarely underst and the MHD
