Which personality types are most compatible?

No pairing is reliably best. Shared middle letters usually make conversation easier, while opposite pairings tend to be complementary once both people learn to translate. Relationship research points to communication and repair habits, not type matching, as what predicts success.

Does a higher overlap score mean a better match?

No. The score only counts how many of the four letters are shared. Similar types understand each other quickly but tend to share blind spots; very different types need more translation but cover more ground between them.

Can I share a specific comparison?

Yes. The web address updates as you change the two types, so you can copy the link and send that exact comparison to someone.

How to read this

Type similarity isn't the same as compatibility. Two matched types tend to understand each other quickly but can share the same blind spots. Opposite types (0% overlap) often build the deepest complementary partnerships once they invest in translation.
