True but still. It's something not to forget. Look at thought
  experiments, commonly in use in education. They're fine as
  limited educational tools to draw limited conclusions in a
  limited field. But then people like to broaden to make
  wide-ranging implications for reality. And then you run into a
  problem: they're thought experiments. Constructed. Precise.
  Fitting the criteria set aside in a closed universe situation
  that may or may not fit reality as it is. In the case of this
  video, it's _possible_. That's what's intriguing: It's
  _possible_. But it's idealised. Fictionalized. We may know of
  situations that 'seem similar' but are they? Family scenarios in
  particular are often _very_ complicated things and while they
  may seem to fall under scripted lines much of the time, there's
  often far more at play than simplified plays designed to prove
  specific points. Anyway, it's part of my overall rant against
  stereotyping in general. A useful tool can sometimes be taken
  too far and people base real life decisions on stereotyping
  guidelines. Some lead to people dying. So, I go a little
  overboard sometimes tongue emoticon
