From my perspective, “group rationality” means how much the group provides an environment conductive to becoming more rational (for those who have the propensity to do so).
It is probably easier to describe the opposite—a group where religion and woo are high status, skepticism is considered a form of stupidity, members are encouraged to think in slogans rather than inspect the details of their actual experience, etc.
A rational group would then be one where as an individual rationalist you can do the right thing without getting socially punished in turn, and are gently called out when you do something stupid.
And it is a “more or less” thing, rather than “yes or no”. (However, the same is true about individual rationality.) I would not expect any group to share all my beliefs and motivation. But the difference between sharing 20% or 80% of the beliefs and motivations means a lot to me.
