i think the ILI builds barriers more out of fear... not out of an attempt to toy with someone. once someone is too close it causes fear and the retreat back into one's inner world for safety out of fear of not being able to handle it or fear of invasion... the particular fears may depend on the person.

i thought beta was more the quadra that wants to set up the deliberate gauntlet test or whatever: prove you can break through my barriers to show you are worthy.

(and of course, some people do deliberately toy with others, regardless of quadra)
