Gaming is purported to hold promise for education, in part, because it is thought to develop 21st century skills such as critical thinking. To date, there has been a dearth of generalisable research investigating the relationship between gaming and critical thinking. Results of a survey of 121 adults found that gamers and non-gamers do not differ significantly on critical thinking dispositions. However, gamers who play strategy games scored higher on actively open-minded thinking than did other types of gamers. In addition, low compared with high involvement in the gaming community was associated with higher open-minded thinking. Implications for educators and for further research are discussed.
