Adults tend to be better at measuring risk as well: picking a fight with me, for example, would mean voluntarily engaging in a physical confrontation with a fully grown, professionally trained combatant who happens to be a member of the most violent species ever known to exist in the universe. If you attack me, one of us will become a murderer. There's little reason to go down that road, and I'll make sure you know it.

However, children don't really think, nor are they permitted to follow through on that kind of threat. And they tend to care more about what they are permitted to do.
