MBTI Friendship Compatibility

ISFJ

the snack bag

ISFJ friendship compatibility: best friends with ISFP. As a friend, ISFJ is the snack bag — the one with tissues, gum, a spare umbrella and your favorite cookie in their backpack. The stereotype paints ISFJs as kind, loyal and observant, the friend who remembers how you take your tea and quietly helps you move apartments without being asked. They can say yes too often and need friends who notice when they are tired. In our friendship rule ISFJ scores highest with ISFP, who shares the S, I and F and brings a gentle, spontaneous side to an ISFJ's dependable routines. The hardest friendship on paper is with ENTJ, the trip organizer, whose blunt, fast decisions can steamroll an ISFJ who would rather keep everyone comfortable.
