You can exclude people whose type you don't really have a good guess for.
1) INTP: 15
2) ISTP: 14
3) ENFP: 13
4-5) ISFP/INFP: 9 each
6) ENTP: 8
7-8) INFJ/ENFJ: 6 each
9-12) ESFP/ESTP/INTJ/ISFJ: 5 each
13-15) ISTJ/ESTJ/ENTJ: 3 each
16) ESFJ: 2
INTP at #1 is not surprising. I am surprised that I know that many ISTPs, but this is a type I like more and more as time goes on. It's interesting that the three most common types among my contacts are the three types I consider closest to mine. Does this happen for anyone else?
There are only 2 ESFJs in my phone and one of them is my mom.
