I couldn't read more than a paragraph of this article it's so ridiculous. The idea that positive reinforcement is a radical idea? Ridiculous. The idea that you can ignore destructive behaviour until it goes away? Ridiculous.
It's about addressing the situation. As a parent the best thing is when I get to positively reinforce my child's behaviour, because it means I've seen them do something wonderful. (Helping a sibling, taking initiative, etc.) But if I didn't stop them when they are throwing toys at their little brother or sister then we've got bigger problems.
That's the core issue. Lots of bad habits don't lend themselves well to only positive reinforcement because the habit itself provides a positive reinforcement to the individual. They'll continue to do whatever because it's fun even if it's self-destructive in the end.
You captured my thoughts on this as well. Positive reinforcement is great and all, but there needs to be an options for a "stick" rather than always a "carrot". Your example is good, but also when they are acting out in public especially if it affects others around them.
