Hi!

This might be a silly question but I'm a bit confused. The 'Two-Value Systems' discussion references inferences to be drawn when there are two groups and all the variables are assigned to one or the other, eg, group 1 and 2. But don't the same inferences apply to 'in and out' groups also, eg, if 4 variables are out of 8 are selected? Wouldn't I just substitute 1 and 2 for 'in' and 'out' and draw the same inferences?

(If H is in then L is in, contra: If L isn't in then neither is H = if L is out then H is out?)

Thanks!

Yes, they typically would, and you do in fact do so in those cases, just without the sub-1 and sub-2 designations. However, for some reason, people seem to understand that in/out idea quite clearly, but when you apply the same idea to two groups where there is no "out" group, the concept becomes entirely harder to follow, hence our use of that term for that specific scenario
