This splits off in at least two ways, doesn't it?
One is the feeling of hypocrisy. Of deliberately being false, not showing one's true self.
A debit against honesty, as the entry price for acceptance.
There are huindreds of negative and positive stories here about what can happen when the mask slips, or is put aside. People celebrated for their originality, and others attacked for their oddity or non-conformity.
The other "cost" is independent of the above, and comes from having to dedicate more mental resources to activities that others may be running almost automatically.
(There's a computer analogy to be developed here, if anyone is inclined...)
Even if the aims of the deliberate social interaction are seen as good and beneficial, not false and a pretence, they still seem to require significant effort. Practice and familiarity does help, certainly, but does not totally eliminate the cost of "thinking one's way" through the maze of the world.
Better not to think? A few writers and thinkers(!?) have considered this a possibility.
