I recently came across this article in a journal called "Consciousness and Cognition." The piece is a study done on mixed handedness and belief change. Oddly enough, the research shows that people who use their non-dominant hand more frequently are more likely to self-reflect and to update their belief systems. The idea is that by using the off hand more, the two brain hemispheres communicate more, which is also something that is necessary for us to update our belief systems. It makes me wonder if offices should be laid out to encourage people to use their off hand, and thus make them more open to new ideas.
