Did I read this correctly? That of the 538 participants, the single largest group (191)--and it was larger by a fair margin over all the other groups -- scored as INTJs?
Here's the story on INTJs from the MTBI people: 2.1% of the adults in the US are INTJs. "They like to solve complex problems through generating new ideas and concepts and developing logical solutions. They enjoy intellectual challenges and are good at creating new systems and with conducting technical analysis. INTJ’s like learning new ideas, are very independent and focused and question and challenge ideas before accepting them. They are skilled at strategic planning and at implementing their plan." [See http://www.coscc.cc.tn.us/careerservices/MBTI%20Types/INTJ.htm]
So, here's the interesting question. INTJs are uncommon in the population to begin with, and a strong plurality of the poll participants identified as INTJ. Why would that be? Is there any comparable data for DUers, or Daily Kos? What a fascinating comparison that would be...
| Type | Adult Population Percentage | FR Members | FR Percentage |
| ISTJ | 11.6 | 59 | 11.3 |
| ISTP | 5.4 | 9 | 1.7 |
| ESTP | 4.3 | 1 | 0.2 |
| ESTJ | 8.7 | 14 | 2.7 |
| ISFJ | 13.8 | 30 | 5.6 |
| ISFP | 8.8 | 7 | 1.3 |
| ESFP | 8.5 | 4 | 0.8 |
| ESFJ | 12.3 | 9 | 1.7 |
| INFJ | 1.5 | 58 | 11.1 |
| INFP | 4.4 | 27 | 5.2 |
| ENFP | 8.1 | 19 | 3.6 |
| ENFJ | 2.5 | 33 | 6.3 |

Truly I wish the posters at those sites would do a project like this - it would be fascinating to compare the results!
