I like your constructiveness in searching for a solution,. However, it seems to me that any data based upon 'categories' which are constructed out of poorly-operationalised variables are not going to be particularly valid, linear algebra or not!
Edit: to be fair, we don't know how they got to their categories, but the naming of them inspires no confidence.
- tpeo 10y agoI wasn't previously acquainted with the term "operationalization" as used in this sense. Okay, it may turn out that this categorization is no better than Humourism, which seem to have suffered of the issues of poor variable operationalization as you described: ancient doctors frequently heaped together distinct phenomena ("hot" meant anything which was hot to the senses, whether it was a glowing hot iron, a flesh wound or a bowl of Jalapeños). But I don't think it's quite the case here: they're grouping users by their choices in a game. That's well defined enough, isn't it? The names don't arouse any suspicion to me, either. I think it's just a case of researchers trying to "sexy up" their findings. It's something that might happen almost involuntarily: either because they started with a sexier model in their minds, or because in seeing their findings, it just came up to their minds and stuck there. I'm actually rather hard pressed for real examples right now, besides calling the transfer of a quantum state "teleportation" (because I just readn about that today), but it's something that happens quite often.
