This is a terrible study. Firstly, it relies on two different sources of information about people's hobbies: detailed biographies for Nobel laureates and something called the Sigma Xi society for the general scientific population. I'm not sure what this society is or how much information it has on its members' hobbies, but I envisage some kind of form that invites you to name your hobbies. You would expect perhaps not the same level of detail as you'd get from a biography or obituary. The second problem is taking members of the Sigma Xi society as representative of the scientific population at large.
