John Lennon ENFP 7w6
Paul McCartney- ESFP 3w2
George Harrison- He's the toughest, i personally think ISTP(The same functions as an INFJ, so i think that's why he gets typed as one. He's not very talkative and he seems outwardly very serious, so that would suggest to me that he's not a dominant perceiver. In early interviews, he also seems like the one in charge, the spokesperson of the group if you like and in one interview he even mentions the future, he talks about starting a business, this might suggest that he's an INTJ, future oriented or whatever but if you read personalty junkie (PJ) it says this- "To understand ISTPs, or other IP types, it is necessary to recognize the full implications of their dominant function being a Judging function. I discuss this issue in my post, Rethinking Judging and Perceiving in IPs & IJs. In short, I suggest that ISTPs are best viewed as predominant Judgers and display many characteristics of EJs, only that these behaviors are directed inwardly or toward themselves."- This would explain why i often see ESTJ when i watch Harrison in interviews. I don't think he's an ESTJ as i think he would have asserted himself more regarding material, in the early days i think he saw himself more as the businessman but then of course he developed an interest in songwriting and of course went on to become a very good one but that was the reason for a lot of tension in the group, he felt kept down by Lennon and McCartney. If you look on PJ, which is my favorite site, you'll see that the ISTP fits him perfectly. Harrison had a spiritual awakening and an ISTP can certainly be spiritual, they have tertiary Ni after-all. The only other type that i can see him as is ISFP( some even think INTJ and they have the same functions). I don't think he is though because he seems to have Fe but you see it develop overtime in the same way that you see Fe develop overtime in somebody like Martin Scorcese( ENTP), if you watch early interviews and then later ones, you'll see his Fe develop, of course the argument could be, well maybe he just became more comfortable in front of the camera and i'd say that's nonsense because if you were gonna act in some way or put on a kind of act, it would be more hammy or whatever and i couldn't imagine Harrison playing up to a camera, i'm seeing inferior Fe,. He has a harder edge than an ISFP i think and also his humour(i don't think in that interview), could actually be very biting and also he could be a bit.......hmm, well he would make little digs at Paul in interviews and that could be seen as slightly passive aggressive, which is more characteristic of a Ti or Fi user, so i personally think he's an ISTP, my second guess would ISFP.
Ringo Starr- I do love Ringo but i haven't seen many interviews with him, i would guess XSXP
