I did an small experiment once: giving typical logic puzzles to friends (generally oriented to exact sciences) and family (mother, grandmother, girlfriend now wife, etc). The family group performed faster. I review the methods of each group and the friends group tried to use more formal methods.

Obviously none of these people were hardly into solving puzzles. I think novelty and lack of frustration in this field makes motivated people perform better. Take this with a grain if salt but there are neuroscience studies pointing to novelty as a good way to learn. It is easy to find studies about it like https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3858647/
