Psychological Type and U. S. Political Party Affiliation
Do your psychological type preferences relate to your political party affiliation? Your political ideology? This article suggests that psychological type preferences indeed do influence both of these political orientations.

One of the first things you might have noticed is that the distribution for party affiliation is fairly equal for many of the types, particularly for the ENFPs and ENFJs. In comparison to this pattern for the ENFs, however, the INFJ pattern shows a clear inclination for this type to report an affiliation for Democrat (49%) and away from Republican (22%). The mirror to this pattern can be seen in the responses of the ESTJs, who show a fairly clear preference for Republican (46%), although a respectable 32% of ESTJs indicate an affiliation with Democrats. Just as interesting, however, is the comparison of the INTs with the INFs in terms of Democratic vs Republican affiliation. So, one question that arises is "why do INFs differ from these Thinking types in terms of Democratic vs. Republican affiliation?" We'll present one possible answer below.
Another interesting pattern concerns the NTPs: ENTP and INTP. These two types appear inclined to declare a stronger affiliation with Independent than do most other types (49% and 45%, respectively). These results are mirrored by the results for the SJs and particularly the STJs. As can be seen, the STJs (ISTJ and ESTJ) report the lowest levels of affiliation with the Independent label (28% and 22%, respectively). Thus, another question that arises is "why do STJs differ from NTPs in party affiliation?".
Finally, at look at the four corners of the type table (the "hard edges") shows the TJs clearly affiliate with the Republican Party more so than most of the other types. As can be seen, at least 40% of each of the four TJ types (ESTJ, ENTJ, ISTJ, INTJ) indicate a Republican affiliation. Our third question thus is "why do TJs tend to affiliate with Republican?".

On the same topic, but with a focus on values, you might find the video from TED Talks of interest. Psychologist Jonathan Haidt studies the five moral values that form the basis of our political choices, whether we're left, right or center. In this eye-opening talk, he pinpoints the moral values that liberals and conservatives tend to honor most.
