I've found that in dealing with clinicians with degrees in social work or education their own ungiftedness (stupidity) either biases them against the gifted (or merely capable) client or otherwise impairs their ability to come to a reasonable diagnosis. Plainly stated, if they get confused because client uses "big words" (my counselor made this complaint and told me I had to "dumb down"--the word in question was "pedagogical"), the client is "thought disordered". If the client had or has aspirations to be something "more" than a MSW, client is grandiose.
What I found most objectionable is that if I did not identify myself as "high IQ" or gifted, my differences were misunderstood. If I identified myself as gifted, doing so meant I had narcissistic personality, or delusions, and so on.
