I think what @D-FB is hinting at one of the cognitive biases aka
There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior. For example, when getting to know others, people tend to ask leading questions which seem biased towards confirming their assumptions about the person. However, this kind of confirmation bias has also been argued to be an example of social skill; a way to establish a connection with the other person.
This is why for critical discussion as in case say with legal structure, I would advocate deliberately inviting in contrary opinions including those who don’t want a legal structure.
I notice this in traditional govts in that the various commissions always seem to be leading towards extending govt regulation, never reducing it 
After all, if there was no problem to be solved, they wouldn’t have a reason to exist …
