Sort each experience by whether it belongs to primary or to secondary socialisation.

Primary socialisation: Acquiring a first language from those who raise you, Learning that some feelings may be shown and others hidden

Secondary socialisation: Learning the unwritten rules of a first workplace, Adapting to the conventions of a profession during training, Taking on the vocabulary and loyalties of a peer group at fifteen

Berger and Luckmann’s reason for the distinction is that the two processes work differently. Primary socialisation has no competition and enormous emotional weight, so what it installs feels like reality itself; secondary socialisation always arrives at a person who already has a world, which is why it can be resisted, compartmentalised or dropped on leaving the job.
