As others have pointed out, simply knowing about socionics does not generally lead to self-improvement or being more accepting of different types. So you have essentially two ways to use it fruitfully:
1. Externally organizing people (as with hospital or college roommate situations, or arranged marriage)
2. Helping people who are already predisposed to internal growth, such as for counseling (including marriage counseling) or spiritual development. It's more important here for the counselor or spiritual guide to know about socionics and its terminology, the person they're helping would mainly need the "plain language" version of what's going on.
The problem with #1 is to put boundaries in place so that it doesn't become some 1984 type situation where your whole place in society is decided for you by the government based on your type. And like @
Olimpia said the whole idea of quadra segregation wouldn't be so great when it comes to understanding other types. I think it would be ok in moderation.
#2 is really where socionics shines IMO.
