I really think that any type can hold any belief system, any political ideology, any career, etc... Granted, they may be a bit more likely to swing in certain directions than others. But I am certain (for example) that every type has been not only represented in social work, but that examples of every type have been happy in their social work careers.
To me the point is more that your approach and your rationale for your beliefs, your politics, career, etc will vary under the influence of type. But there are SO many other factors besides type.
