The 23(a) criteria are referred to as numerosity, commonality, typicality, and adequacy. Basic criteria are, like in the US, numerosity, commonality and typicality. This updated TLC is capable of explaining both the familiarity effect and the typicality effect.

Strong typicality is often easier to work with in proving theorems for memoryless channels. A very common use of hedges can be found in signaling typicality of category membership. There is so much humor and typicality in them.
