My take away is not that people should blindly copy the technique, but draw inspiration on why they work. Yelling is just an other fear method, either by threatening the child by violence (I am loud so I represent danger to you), or threatening by abandonment (I am angry at you and socially might not like you any more if you continue to misbehave). Both can be very damaging to the children mental development.

Which method that is best to get a child not to run over the road without looking is debatable.
