1 = WHEN FI/FE ARE CORNERED IN A DEAD-END IN A SPECIAL KIND OF THREATENING SITUATION:
it's Fe's that are probably going to react passive-aggressively, whereas an Fi will take more of an active, personal stand.
2 = WHEN FE/FI ARE NOT CORNERED AND FE/FI CAN DO THEIR NORMAL JOB:
Fe's are more direct conflict resolvers, Fi's will be more passive and try to keep the mood light.
so when cornered, the fi/fe-doms do the inverse of what they normally do. (they use the "opposite underdeveloped function" in a primitive way when the developed function is cornered)
