I think I probably started this with book reading. I think of it as a hobby, but rigorously I'd say it falls more under entertainment. The criteria chosen for the distinction between hobby and entertainment (and it is, of course, a continuum between them) is how much personal effort or creativity goes into the activity. I'm not sure that's well-defined. For example, there's a third axis that's not even being considering yet: that of sport. Most sports would be classified as hobby because of the effort involved - which is why effort is in the criteria - not all hobbies have creativity as their focus. The easy-to-define activities cluster around the ends (though where they are in relation to each other at each end is highly arbitrary). I'd like to fill in the chart more, especially in the middle, though I don't want to have to list every activity known to humanity, maybe just some typicals. I'm curious about personal activities that might put the lie to this generalization. Are there activities that require a lot of personal effort/input, yet might still conceptually fall under entertainment? Are there activities that require little input or effort that might be considered hobbies? Where would you put group card games? What about crossword puzzles? Is the terminology sensical? Is there a more diagnostic term than personal creativity/effort input? Please Register or Log in to view the hidden image!
