This man is correct. The word is as specific as hippie or redneck. The pure essence of the word has been lost imo. You especially cannot pinpoint an entire group of people to a single MBTI. The stereotypical hipster, to me, is someone who is outwardly focused on fashion, cutting-edge trends, while simultaneously maintaining their own sense of integrity and uniqueness. I guess you could call it someone who is a free spirit and actively tries to prove their free spirit to others. ESFP, ISFP, and ENFP are mostly likely the types you will find within stereotypical groups of hipsters. However, just like there are ESFP and INTJ businessmen, there are definitely ESFP and INTJ hipsters.There are no "brands" of hipsters based on MBTI types; thinking such a thing is pure crazy talk. In my locale there are overlapping cliques of hipsters. Within each group is a variety of types but the NFs seem to be in the majority. Overall, they seem to be slightly more extroverted than introverted but that is just from my personal observations based on who is out and about on a regular basis. In my experience, the most talented musicians and artists are typically I's.
Finally, the idea of what a "hipster" is has become so blurred over the past 10 years or go. Hipster culture has been commodified, mass marketed and homogenized to the point where it's essentially gone semi-mainstream. It's become just another lifestyle product brand for North American consumerbots to embrace. Conceivably, any type can now comfortably jump on the hipster bandwagon. In years past you would probably find few, if any, SJ types involved in a counterculture. Today there is practically no cultural stigma (at least in the larger metro areas) against things like sleeve tattoos, multiple piercings, over-sized plastic frame glasses, ironic mustaches and using a bicycle as a primary means of transport.
Bah. Sorry but no. l would say that's true about many introverts but l sense a quiet sort of attention seeking quality from some. This isn't "forcing" quirks on people but it is drawing attention to your own qualities.Extraverted, to be sure. The nice thing about introverts is that they don't force their quirks upon the rest of the world.
