Are you an ENFP struggling to connect with your INTJ significant other? We’ve all been there.

If, however, that sentence made no sense to you, then you might not be a millennial.

ENFP and INTJ are “types” described by the Myers-Briggs Indicator Test, a 60-year-old personality test that is experiencing a cultural renaissance of sorts thanks, in part, to readers of millennial publisher Thought Catalog. After a Thought Catalog post by staff writer Heidi Priebe called “The Definition of Hell for Each Myers-Briggs Type” went viral on May 14, 2015, Google searches for the term “Myers-Briggs” skyrocketed to 100 on the 0-to-100 scale. The search term has hovered around 2o-30 since then.

Priebe  inspired a slew of imitators (Myers-Briggs type: ENTP, probably). Wired, Fortune, Flavorwire, and Bustle all glommed on to the Myers-Briggs beat in May and June with their own riffs on the trend. Now you can read up on best classic books for Myers-Briggs types, the potential for personality data in workplace communication, and the scientific shakiness of the test itself. It’s also a feature of online dating profiles with high millennial usage, notably Tinder and OkCupid.
