I’m a fan of chaperone proteins But I’m a little concerned reading this as such human [social] chaperones become a justification for a “middle management” citizen police, disseminating orders from above and informing the above at any groups that are considered dangerous to the above.
For subtle influence, which is chaperone in nature – and the article talks about – I can see its usefulness. But it could also just as easily become a “shill” – a north american term “an accomplice of a hawker, gambler, or swindler who acts as an enthusiastic customer to entice or encourage others.”
I don’t think it works any differently in Japan. IUT is a difficult study as it touches into areas of number theory that are usually left alone but any culture is capable of doing.
